摘要: Abstract Temperature distribution and weld bead profiles of constant current pulsed gas tungsten arc welded aluminium alloy joints were compared. The effects welding on tensile properties, hardness profiles, microstructural features residual stress reported. use technique is found to improve the properties compared with continuous due grain refinement occurring in fusion zone.
