Optimising a multipass arc welding procedure

Abstract

Synopsis:A new approach to optimising production process procedures is applied to the multipass welding of a butt joint with a single V groove, for a range of thicknesses. The process used is CO, gas shielded automatic welding with a 1.6 mm diameter cored wire. The chosen optimisation criterion is the minimum of a performance index based on the weld penetration and section.
