The research of technological and environmental conditions during low-energetic gas-shielded metal arc welding of aluminium alloys

Abstract

In this paper, two trends of research conducted at the Welding Institute have been presented, namely the study of material and technological welding conditions of different aluminium alloys using CMT and ColdArc methods and the influence of selected technological parameters on emission rate to the working environment. The properties of welded joints as well as the application fields of modern low-energy welding devices for joining thin aluminium sheets have been discussed. The relationships between the welding method, base and filler material type, and emission rate have also been presented.
