Abstract

Important issue is the formation of a quality weld at low temperatures. Different factors influence the qualitative suture: material, weather conditions of welding, what method is welding, current, voltage and many others. The problems of the effect of negative temperatures on the parameters of the seam, various ways of improving the welding process are considered: preheating, application of heat-resistant belts and others, and also testing of the weld seam for defects.
