Robot Welding Process for Medium and Heavy Plate

摘要

Welding processes are always required to have highefficiency, quality stability, and reduced costs. The advanced controllability of the welding power sources has enabled the control of the output waveform, using an advanced control law, which has realized a new process with high added value for medium and heavy plates, the Ultra-High Current GMAW process, tandem arc welding and REGARC TM . The Ultra-High Current GMAW process is a highly-efficient welding process using single arc and offers large leg length, low-spatter and deep penetration, using special flux-cored wire and unique waveform control. Tandem arc welding reduces spatter generation by 70 percent compared with conventional equipment, thanks to its new waveform control. The advantage of this welding process is a high deposition rate and high speed welding. REGARC TM reduces spatter generation by 90 percent compared with the conventional process using CO 2 gasshielded arc welding.
