Laser-gas metal arc (GMA) hybrid welding is fast, good for deep welding, and can be used to bridge large gaps. However, for thicker high-strength, fine-grain structural steels, hot cracks and ...

High strength steel and aluminum, as far as welders are concerned, are some downright temperamental metals. High-temperature welding twists and warps the metals, leaving companies like Boeing, ...

Lappeenranta University of Technology (LUT) is developing an entirely new kind of welding system, one which solves quality and productivity problems related to automated and mechanised welding. The ...

Scientists at the Fraunhofer Institute for Mechanics of Materials IWM have developed a new process for making cold cracking in high strength steel more predictable. Cold cracking currently presents ...

Developed primarily for high-strength applications, these steels are usually heat-treated alloys that provide strengths at least equal to those of as-rolled steel. Heat-treated constructional alloy ...

Scientists are developing an entirely new kind of welding system, one which solves quality and productivity problems related to automated and mechanized welding. The system is self-adjusting, flexible ...
