If possible, preheat the welding position to 100 degrees.Then use the welding rod with a diameter of 3.2J507 for welding, and stop after a short time of welding.

After the welding is completed, use the hammer to strike until the weld is basically cooled.The purpose is to release the weld stress, since post-weld heat treatment is not possible.
