Possibilities Of Using Thermal Affected Zones And Special Welding Methods In Repairing Machine Parts And Metal Structures By Welding

Abstract

This article analyzes the heat affected zones (HAZ) formed during the welding repair of machine parts and metal structures and their effect on material properties. During the welding process, high temperatures can cause changes in the metal structure, internal stresses, and deformations. The research investigated special welding methods - low-energy welding, laser and plasma welding, pulsed modes, as well as preheating and controlled cooling technologies. According to the results obtained, it is possible to reduce the thermally affected area, maintain material strength, and increase the reliability of repaired parts by using these methods.
