If the wall thickness of the elbow is relatively thick, it is best to perform stress relief heat treatment on the weldment immediately after welding. This is especially true for large-thickness weldments Q235B, high-rigidity structural parts, and weldments that work under severe conditions (dynamic load or impact load).
