Abstract: The article presents the innovative MIG welding technology using variable polarity AC and reveals the results following the investigation of the impact of the EN ratio on the structure and HAZ width of overlay welds.

Abstract: Results of research on application of variable polarity MIG method for welding of thin sheets of 6082 and 5754 aluminium alloys have been presented. The influence of negative component portion in current and voltage course on process stability, joints quality and the microstructure evolution was discussed.

Abstract: The article presents the course and the results of research on material and technological welding conditions of different aluminium alloys using standard (MIG-Pulse) and low energy welding method (CMT) as well as discusses the properties of welded joints and the application fields of modern low energy welding devices for joining thin aluminium sheets.

Abstract: The article presents the course and the results of research on material and technological welding conditions of different aluminium alloys using low energy welding methods (CMT and ColdArc) as well as discusses the properties of welded joints and the application fields of modern low energy welding devices for joining thin aluminium sheets.
