Laser-arc combined welding of 5754 magnesium aluminium alloy was performed with the CO2 heat source and MIG torch. The effects of welding conditions on penetration depth, geometry, porosity and crack susceptibility were investigated. Concerning porosity suppression and key-hole stability, optimal process parameters were identified. The grain boundary wetting phenomenon was observed in the fused zone.

Abstract
Laser-arc combined welding of 5754 magnesium aluminium alloy was performed with the CO2 heat source and MIG torch. The effects of welding conditions on penetration depth, geometry, porosity and crack susceptibility were investigated. Concerning porosity suppression and key-hole stability, optimal process parameters were identified. The grain boundary wetting phenomenon was observed in the fused zone.File in questo prodotto:
