Effects of welding on materials

Welding can significantly alter the properties of materials, leading to changes in microstructure, mechanical strength, and overall performance. The heat generated during welding can cause thermal expansion, leading to residual stresses and potential warping. Additionally, different welding techniques can introduce impurities or affect the material's hardness and ductility, often resulting in a heat-affected zone (HAZ) with varying characteristics. Proper control of welding parameters is essential to minimize negative effects and ensure strong, reliable joints.
