WebThe heat should be maintained until the welding is finished. As per AWS D1.1 Preheat is defined as: The temperature of base metal in the volume surrounding the point of welding, immediately before the welding is started. In a multi-pass weld, it is also the temperature immediately before the second and subsequent passes are started. WebInduction preheating can slow down the cooling rate after welding. It is beneficial to escape the diffused hydrogen in the weld metal and avoid hydrogen-induced cracks. At the same time, It also reduces the welding seal and heat-affected zone hardening level, the welded joint crack resistance is improved.
Web20 jun. 2024 · Preheat minimizes the difference in temperature between the base material and the welding arc. The minimal difference translates into several benefits. Preheat is used to protect the metal’s integrity and to prevent brittleness. Slowing the cooling rate (postheat) allows the hydrogen to escape to prevent cracking.
