To address the challenge of porosity suppression in laser-arc hybrid welding of high-nitrogen steel, a weakly coupled laser-arc welding method suitable for high-nitrogen steel is proposed. A test ...

Tandem welding is extensively used for welding large structures, such as ships and plants, for increased welding speed and volume. Seam tracking is essential because of a large amount of thermal ...

Ever try to join two pieces of sheetmetal with an arc welder? It's nearly impossible. Even with a conventional arc welder set on its lowest heat setting, so much heat is produced that it just burns ...
