Abstract

The effect of laser radiation power, welding speed, thickness of the welded material, heat removal conditions on the structure and mechanical properties of the butt-welded joint of a multicomponent Zr—16Cr—16Al—16Ti—16Zr alloy was studied. It is shown that the emergence of residual thermal stresses is an important factor in the softening of the material after laser welding. The regularities of distribution of thermal stresses are determined depending on the conditions of laser welding and the influence of their features distribution on the strength of the alloy after welding Full text download
