Welding
As welding progresses along the joint, the weld pool solidifies fusing the parent and weld metal together. Several passes or runs may be required to fill the joint or to build up the weld to the design size. The heat from welding causes metallurgical changes in the parent material immediately adjacent to the fusion boundary or fusion line.
