Weld the joints as shown in Illustration 21 through Illustration 24.Note: Use a balanced approach to minimize distortion when welding the groove welds. Weld one pass at each joint and then to next joint. Repeat this process until the finished weld size has been obtained. Do not weld each joint to completion before moving to the next joint.
