Abstract

MIG Brazing (MIGB), as well as other hybrid variants, is meant to replace the MIG welding, which usually introduces too much heat in the joint during the welding process. The first main part of the paper describes the influences of the gases on the stability of the joining process and of the melted metal transfer through the electric arc. The influence of the type of the gas and welding speed, as well as other process parameters are addressed. The bead appearance and shape are analysed in the second part of the paper, mainly underscoring the gases influences on the convexity of the bead, its colour, brightness, smoothness and surface pores formation.
