What can excessive heat during the welding process lead to?

Excessive heat during the welding process can lead to an increased risk of joint failure due to warping. When materials are subjected to high temperatures, they can expand and contract unevenly, resulting in distortion. This distortion can compromise the integrity of the welded joint, leading to misalignment or incorrect fit-up, which ultimately affects the mechanical properties and performance of the weld.

High heat can also negatively impact the metallurgy of the base materials, causing changes in hardness, brittleness, or even the potential for cracking as the weld cools. Therefore, careful control of heat input is essential for maintaining the quality and strength of the weld, ensuring that it meets the intended specifications and safety requirements.
