Investigation of the impact of welding parameters on gas metal arc welding

Abstract

In the present work I present the results obtained by investigating the influence of different pulse modes (pulse, double pulse) and the welding parameters in case of gas metal arc welding. Two different welding machines were used in the tests. In both devices, the same material transitions were selected as far as possible and their effect on the joint was investigated. The base material, the filler material and the gas mixture were same in every case. The relationship between metal transfer modes, welding parameters and weld geometry characteristics (external and internal form factor, melt depth, weld width) has been revealed.
