Sensors in the welding environment
Figure 1 A sensor that is not expected to last beyond exposure to 5,000 weld flashes might have a very limited life in a robotic welding cell. Sensors play a pivotal role in ensuring production quality in welding environments. The automotive industry, for example, relies heavily on... Read more...

Lost in translation
Today, myriad proprietary design and inspection languages exist, and none can talk to another without a translator. It's a situation sources liken to the Tower of Babel.
Quality managers at certain industrial heavyweights have a dream: for all digital part data—including elements... Read more...

The right trace at the right time
Whenever a laser is used in an industrial setting, a safety enclosure is usually required. To eliminate the expense of setting up an expensive enclosure room for use of its MeccoMark 20-W, fiber-delivered ytterbium laser marking system, Ford and MECCO engineers developed a safety snorkel on...

Where sensors make sense
Sensor-driven errorproofing can help stamping shops prevent the production of bad parts, die crashes, and downtime. Metal formers today find that increasingly customers are no longer satisfied with just a low percentage of defective parts, measured in parts per thousand. Today customers... Read more...

Measure it, graph it, control it
You have probably heard of statistical process control (SPC), and you probably use it as a tool for quality assurance or quality control. Developed in the 1920s by physicist and mathematician Walter Shewhart, SPC has other uses too. Specifically, it can help to improve productivity and therefore... Read more...

Bend process monitoring—small changes lead to big results
In many advanced fabrication shops, tube bending is a highly automated process that uses robotic and CNC bending machines to produce high volumes of complex tubes, each one formed to precise specifications. Robotic, automated operations are fascinating to watch as the steel tube... Read more...

What do you monitor to ensure quality?
The crimp force monitor is sensitive enough to indicate a process failure when a single sheet of paper disrupts the crimping cycle. This level of sensitivity isn't practical for most manufacturing operations, but it does demonstrate the process variation monitor's capability. It's... Read more...

Assessing developments in orbital welding—Part 2
Editor's Note: This article is the second part of a two-part series about developments in orbital welding. Part I discusses power supplies, weld heads, and electrodes. Part II focuses on hardware and accessories that improve weld quality and software that documents the welds.
The... Read more...
