ガス組成変化を用いた新しい溶滴移行制御技術について －パルスガスMAG 溶接法－

CO2 gas shielded arc welding, which is widely used in the industrial world, has been recognized as an efficient and economical GMA welding process. However, it’s characteristic repelled transfer produces a large amount of spatter results costly cleanup and, thus, practical methods to overcome this weakness have highly demanded. In study, ‘Pulsed Gas MAG’ was proposed new approach reducing spatter. The reduced levels low that conventional MAG with 80%Ar + 20%CO2 shielding mix penetration profiles were round shape like those obtained welding.
