A fabricator that needs to weld thick plate in as few passes as possible often will turn to submerged arc welding (SAW), a legacy process that has dominated heavy fabrication for decades. Variations ...

Cobot laser welding at THG goes back several FABTECHs, during a dinner conversation between company representatives and a custom metal fabricator. The shop owner spoke with the reps about the emerging ...

Hybrid approach combines arc welding with a 20kW IPG fiber laser to reduce welding time for inch-thick steel components by 80%. Engineers at GE’s Global Research division say that a hybrid laser arc ...

APPLETON, WI — Arc welding products maker Miller Electric Mfg. LLC, part of the Illinois Tool Works family of welding brands, announced the release of its OptX 2kW handheld laser welder. The company ...

Researchers discuss an ambitious project to understand the basic principles of laser welding better than ever before. On its surface, the work is deceptively simple: Shoot a high-power laser beam onto ...

As with traditional welding techniques, materials are melted in the weld zone, although laser-based techniques use quicker heating and cooling cycles (Figure 1). These rapid thermal cycles are a ...

Structural applications of steel have long made use of elongated beams with carefully designed profiles, whose geometry gives them specific mechanical properties. Nowadays, the variety of cutting and ...

Traditionally, welding has been limited to materials that share similar properties, so it's tough to make even aluminum and steel join forces. But now, scientists from Heriot-Watt University are ...

Medical devices use a variety of metal components that are often welded to form a secure and permanent bond. Options available for welding processes are limited because of certain constraints such as ...

The development of cheaper, more powerful lasers has always been a cause for excitement among hackers, and fiber lasers are no exception. One of the newer tools they’ve enabled is the laser welder, ...
