First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
It is one way to "Stress Relieve" the weld joint. As the weld metal metal cools it contracts and hammering on the weld expands it. On thick sections it is done after every layer of weld. Often used when welding cast iron or other metals with a low COE (Coefficient of Expansion).
The required size for a seal weld per AISC is eighteen foot length. AISC also specifies minimum weld size based on the thicknesses of the members joined.
