Organizations often have more than one manufacturing site, and each location might have its own specific strengths.

Acommon process for welding thick metal parts is submerged arc welding (SAW). Typically, SAW and other processes require beveling the workpieces to give the torch access to the joint root. The multi-pass process requires high heat input to the weldment and can generate a large heat affected zone (HAZ) along with distortion.

Fabtech, North America’s largest trade show for metal forming, fabricating, welding and finishing technology, took place Nov. 8-10 in Atlanta. Here are five new products on display at the event.

CRANBERRY Township, PA—A Pennsylvania Department of Community and Economic Development grant is funding research to advance the scientific knowledge of laser plastic welding among American engineering students.

VIENNA—Researchers at the Technical University Wien (TU Wien) here have developed multiphysics software that can simulate the ability of dynamic beam lasers from Civan Advanced Technologies Ltd. to weld various materials.

Conventional automobiles contain 20 to 50 pounds of copper. Electric vehicles, in contrast, contain about 180 pounds of copper, and 27 million of them are expected on the road by 2027.

Laser welding of plastic parts creates precise, high-quality, particulate-free joints for medical devices, consumer products and other assemblies. However, for the process to work, the laser light must pass through the top part to be absorbed by the bottom part. Welding a clear plastic part to another clear plastic part was not possible.
