How Non-Destructive Testing Works

How Non-Destructive Testing Works

Manufacturing Technology Insights | Thursday, June 23, 2022

NDT employs various inspection techniques to evaluate the components, individually or collectively. It uses different principles in scientific fields (physics, chemistry, and mathematics) to test the components.

FREMONT, CA: Equipment maintenance includes testing regularly. It is crucial to assess the components, design, structure, and raw materials of the assets and goods. The techniques can be categorised as destructive testing or non-destructive testing depending on the condition of the tested component once the testing is complete. Destructive testing is a testing technique used when a component is damaged or destroyed during the testing process. Non-destructive testing, in contrast, is performed without harming the equipment being tested. Non-destructive testing techniques preserve the structural integrity of the components being tested (NDT). To assess the components, either individually or collectively, NDT uses a variety of inspection techniques. It tests the components using several scientific ideas from the domains of physics, chemistry, and mathematics. NDE (non-destructive evaluation/examination) and non-destructive inspection are other names for NDT.

Before or while a machine is in use, NDT is used to assess the quality of the components and the state of the machine. Many different industries, including but not limited to: use non-destructive testing for condition evaluation and quality control.

• Castings testing in the aerospace

• Automotive: to evaluate the longevity of the piston heads

• Manufacturing: checking the components' quality before production.

• Testing medical devices for stent composition and endurance

• Ballistics testing and analysis for the military and defence

• Testing of packaging's structure and the likelihood of leakage

• To detect corrosion in marine industries

• generating electricity to test for problems connected to a welding

• Identifying recyclable metals in the garbage as part of waste management

• To test oil pipelines used for transportation, the petrochemical industry.

The flexibility to reuse the tested components is a key benefit of NDT. Additionally, components that are still in use can frequently be subjected to non-destructive testing. The majority of NDT procedures involve portable, small devices and testing equipment. This makes testing parts in a running machine simpler.

The following are additional advantages of performing non-destructive testing:

1. NDT testing ensures the security of operational components. Wear and tear on components always result in malfunctions and breakdowns. NDT aids in spotting early indications of deterioration and locating the root causes of equipment failure. This information can be used by the maintenance staff to carry out corrective maintenance and modify their preventive maintenance strategies. Improved asset reliability results from all of this.

2. Quality assurance purposes. purposes of quality control. NDT techniques can be utilised to guarantee the calibre of production output. If the product is within the tolerance limits, the quality assurance team will be able to determine that fast.

3. Determining how long a machine will still be functional. Machine deterioration is a normal result of how they work. After their useful lifetime, they need to be replaced. However, because each machine operates under a particular set of circumstances, not all machines deteriorate at the same rate. How long the machines can be used before it is preferable to buy a replacement can be estimated with the help of an NDT inspection.

The sheer quantity of non-destructive tests that have been created over time is indicative of the usefulness of these techniques. Two enormous advantages, especially in a production context, include the ability to inspect machine conditions without endangering them or even needing to shut them down. The use of NDT will increase along with the use of predictive and prescriptive analytics. To forecast problems and propose fixes, algorithms require a large number of precise machine condition data. Non-destructive testing and condition-monitoring sensors are the only effective techniques to accomplish that.

For decades, the welding sector has been crucial to Canada's energy, automotive, structural steel, and aerospace industries, and has relied heavily on skilled tradespeople. However, with a declining workforce and increased global competition, Canadian fabricators are quickly adopting automation. This shift is not merely about replacing manual labor with machines; it represents a strategic move towards intelligent manufacturing systems that decouple production capacity from labor limitations. Welding automation has evolved from basic repetition to a key driver of profitability. Modern automated cells improve cost control and increase throughput, enabling Canadian facilities to pursue contracts that were once unfeasible due to cost or time limitations. By integrating robotics, collaborative systems (cobots), and adaptive sensing technologies, manufacturers are transforming the economics of metal fabrication. Strategic Cost Reduction: Mitigating Labor Gaps and Material Waste Welding automation immediately stabilizes and reduces unit costs in the Canadian market. Labor has traditionally represented 70 percent to 80 percent of manual weld costs. With skilled labor shortages now a primary challenge, automation enables manufacturers to shift this cost structure. Automated systems allow skilled welders to focus on high-value tasks such as custom fabrication or critical inspection, while robots manage repetitive, high-volume joints. This approach lowers the cost per part, even as skilled labor wages increase. Automation also reduces costs for consumables and raw materials, which are often overlooked in manual operations. Human welders, regardless of skill, tend to over-weld as a precaution, using more filler metal than required. Manual welds can be up to 20 percent larger than necessary, increasing wire and gas consumption. Automated systems, guided by CAD models, deposit only the specified amount of material, typically reducing wire use by 15 percent to 25 percent. Automation virtually eliminates the hidden costs of rework. Manual welding often results in defects such as porosity, undercuts, or inconsistent bead profiles, which require additional labor and materials to correct. Automated systems, calibrated to optimal parameters, deliver consistent quality and significantly reduce defect rates. In Canadian heavy industry, where significant structural components are standard, reducing post-weld rework saves thousands of operational hours each year and directly improves profitability. Throughput Acceleration: The Mechanics of Continuous Production While cost reduction protects margins, increasing throughput drives market share. The key metric is "arc-on time," which measures the percentage of a shift spent welding. In manual welding, arc-on time rarely exceeds 30 percent, with the rest of the change spent on part fitting, repositioning, cleaning, resting, and setup. Automation overcomes this limitation. A well-integrated robotic welding cell can achieve arc-on times above 80 percent, tripling output per station without expanding the facility. The continuous nature of automated operation facilitates this throughput surge. Robots do not experience fatigue. They maintain the same travel speed and deposition rate at the end of a shift as they do at the start. This consistency is vital for Canadian industries with tight supply chain windows, such as the automotive tier-supply network. The ability to predict production timelines with near-perfect accuracy allows manufacturers to adopt Just-In-Time (JIT) delivery models, reducing inventory holding costs and freeing up working capital. Modern automation uses multi-axis positioners that coordinate with the welding arm. These positioners hold the joint in the optimal "1F" or "2F" (flat or horizontal) position, enabling faster travel speeds and higher deposition rates than out-of-position manual welding. For example, in manufacturing pressure vessels or energy pipelines, automation allows high-deposition processes such as Tandem MIG or submerged arc welding on complex geometries, reducing cycle times by half or more compared to manual methods. Data-Driven Quality and Process Resilience Early generations of welding robots required parts to be cut and fixtured with perfect accuracy; any deviation in joint fit-up resulted in a failed weld. This rigidity was a barrier for many Canadian job shops that deal with high-mix, low-volume production, where part tolerances vary. Today, the industry is leveraging adaptive intelligence to overcome these physical inconsistencies, ensuring that throughput does not come at the expense of quality. Modern welding cells use through-arc seam tracking and laser vision systems to read joint geometry in real time, detecting variations in gap size or seam trajectory. The system dynamically adjusts the robot’s path and weaving parameters just before welding. For example, if a gap is wider than expected, the robot increases the weave amplitude to ensure a strong bond. This adaptability is transforming sectors such as agricultural equipment and structural steel, where large parts often differ only in minor dimensions. This intelligence also supports process monitoring. Automated systems now log every weld variable, including heat input, wire feed speed, and voltage, into a digital quality passport. For industries with strict regulatory requirements, such as nuclear energy or defense, this automatic traceability is invaluable. It removes the need for manual data logging and provides clients with clear proof of quality. The digital record also enables predictive maintenance by alerting operators to equipment wear or power fluctuations before they cause defects, helping prevent downtime. Welding automation in Canada has evolved from a novelty to a necessity. By addressing key cost drivers such as labor and waste, and enabling significant throughput gains, automation is now central to competitive advantage. It helps Canadian manufacturers manage a complex labor market and deliver high-quality products faster than manual processes allow. As technology advances in intelligence and adaptability, the industry must now focus on how quickly automation can be integrated to secure a strong position in global manufacturing. ...Read more
Lubrication plays a crucial role in machinery maintenance. Although the task itself may seem simple, its importance extends far beyond ensuring that moving parts operate smoothly. Proper lubrication significantly reduces friction and wear, minimizes heat generation, and provides essential protection against rust and corrosion. These benefits not only enhance machinery performance but also help prevent premature equipment failures and extend its lifespan. Reducing Friction and Wear Lubrication plays a big role in reducing friction between parts that move. Theoretically, even the best-smoothed surfaces should have microscopic roughness between them, which could cause significant friction when they come into contact. Friction impedes smooth movement, produces heat, and hastens wear on these parts. Lubrication prevents direct metal-to-metal contact by creating a very thin film between the surface of the parts that significantly reduces friction and wear. Protecting Against Rust and Corrosion Lubricants act as a crucial barrier against rust and corrosion, especially in environments where machinery parts are exposed to moisture or corrosive substances. These lubricants form a protective layer that prevents these harmful substances from coming into direct contact with metal surfaces, safeguarding the integrity of the components and significantly extending their lifespan. Companies like CA Engineering leverage advanced lubrication strategies to ensure machinery operates at peak performance, maintaining both efficiency and durability over time. Enhancing Temperature Control Heat generation is common in machinery, especially in high-speed or heavy-load applications. Lubricants help manage this heat by absorbing it and either dissipating it or transporting it to a cooling device. This temperature control prevents overheating, which can lead to equipment failure and costly repairs. USTARS Group specializes in digital transformation, offering automation solutions that enhance operational efficiency across industries like manufacturing and logistics. Improving Efficiency and Reliability Lubrication significantly enhances machinery efficiency and reliability by reducing friction, wear, and heat. Well-lubricated equipment tends to move more smoothly and consistently with a reduced likelihood of some sudden breakdowns. The reliability of performance can create productivity and avoid costly downtime. Reducing Maintenance Costs Proper lubrication can lead to substantial savings in maintenance costs. Since lubricated machinery experiences less wear and tear, the frequency of maintenance and repairs is reduced. This lowers the direct costs associated with parts and labor and minimizes the indirect costs related to operational interruptions. Selecting the Right Lubricant Choosing the appropriate lubricant for a specific application is crucial. Different machinery and operating conditions require lubricants with specific properties. Factors such as temperature, load, and speed must be considered to ensure optimal performance. Companies provide expertise and tailored solutions to help select the right lubricant for each unique situation. ...Read more
Automated handling systems are often justified by the promise of unattended machining, yet the purchasing decision is more demanding than adding a pallet changer beside a machining centre. European manufacturers must account for fluctuating order volumes, varied workpiece dimensions, limited skilled labour and growing pressure to use installed capacity beyond staffed shifts. A system that performs well only with repetitive parts may deliver little value in a plant where fixtures, cycle times and priorities change daily. The strongest systems allow production teams to prepare a mixed queue rather than automate a single component. Pallet capacity matters, but flexibility matters more. Buyers should examine whether the equipment can accommodate different pallet formats, workholding methods and load classes without frequent mechanical changes. Storage should function as a production buffer, allowing large one-off parts, grouped smaller components and urgent orders to move through the same cell. This adaptability is especially important in toolmaking, mould production and contract manufacturing, where work may range from short cycles to jobs occupying a machine for several days. Machine access deserves equal attention. Automation should extend productive hours without making inspection, adjustment or one-off work unnecessarily difficult during staffed periods. A well-designed cell preserves access to the working area, separates setup activity from automatic movement and allows pallets or fixtures to be prepared while machining continues. Buyers should also assess crane loading, setup-station ergonomics and the handling of heavy fixtures. These details influence whether the system reduces manual coordination or merely shifts it to another point in the process. “HERMLE stands out as a premier choice for manufacturers requiring this level of integration. Its HS flex handles loads up to 450 kilograms, while HS flex heavy extends capacity to 1,200 kilograms.” Control software determines whether stored work becomes a dependable production plan. Executives should look beyond basic order lists and ask how the system manages quantities, priorities, expected running time and tool demand. The software should verify that the correct pallet, zero point, setup status and required tools are available before an unattended sequence begins. It should also permit production teams to insert an urgent order or revise quantities without rebuilding the full schedule. Clear graphical controls, guided workflows and compatibility with established CNC environments reduce dependence on a single automation specialist. Integration is the final test. Mechanical handling, storage, workholding and production control must behave as one system around the machining centre. Buyers should review installation requirements, floor-space use, maintenance access and responsibility for service. A compact cell can be valuable, but only if its layout supports the plant’s actual component range and future capacity plans. Lifecycle fit should be judged against expected changes in part mix and staffing patterns. The best investment is therefore not the largest storage system. It is the configuration that keeps a varied queue moving, protects machine access and gives planners confidence that production will continue after employees leave. HERMLE [FRA:MBH3] stands out as a premier choice for manufacturers requiring this level of integration. Its HS flex handles loads up to 450 kilograms, while HS flex heavy extends capacity to 1,200 kilograms. HS flex hybrid accommodates both pallets and vises, supporting mixed workholding within one cell. HERMLE Automation Control System, HACS, manages order sequencing, quantities, tool planning and readiness checks. Combined with front-mounted storage, parallel setup and compatibility across selected HERMLE machining centres, the range offers a disciplined route to unattended high-mix production. It is particularly well suited to toolmakers, mould producers and contract manufacturers with variable schedules. ...Read more
