Whether you need to measure dimensions or perform some sort of flaw detection on sheet, tube, or pipe, you'll find what you need in this technology area. It discusses measuring coordinates, diameters, and hardnesses; flaw detection using eddy current, ultrasonic, radiographic, and X-ray systems; and using a few other equipment types, such as vision systems and material composition analyzers.

Statistical process control (SPC) often is used to reduce the number of manufacturing defects. However, it has other uses also. It can serve to increase productivity and therefore improve a company's profitability. Statistical tools and Pareto diagrams can help you to track manufacturing problems and put you on the trail to finding their causes.

To ensure quality welds, it is important to have a quality weld inspection program in place. In order to do so, a company must understand how to evaluate weld characteristics, determine weld quality, and have a welding inspector capable of performing a number of different testing methods.

Conventional quality control in tube bending operations usually means detecting the number of links on a tube bending mandrel. When such a system detects that a mandrel link is missing, it shuts down the system so personnel can discard the last bent tube and replace the mandrel. Unfortunately, the broken mandrel link usually is a symptom of a larger problem—one that may have produced poor-quality parts long before the mandrel broke. br> br>Another method, process variation monitoring, measures the tension on the mandrel and alerts the equipment operator when the tension changes. This lets the manufacturing personnel know that a problem is developing while it is still small and manageable.

Good welders learn to inspect their own work, but welders are just one part in a long list of variables (and people) involved in ensuring quality welds. Thorough communication of the welding parameters, as well as proper training to carry out the design, can help welders achieve quality work and to reduce the number of rejected welds.

Manufacturing processes are prone to variances, resulting in manufactured products that do not conform to specifications. Dozens of types of electronic sensors and measurement systems are available that fabricators can use to verify that their products are not defective. Understanding what types of sensors are available and how they work are the first two steps in implementing electronic sensing devices for quality control.
