Coalescence (welding)
From Wikipedia, the free encyclopedia
Coalescence is a term used in welding. Two (or possibly more) pieces of metal are bonded together by liquefying the places where they are to be bonded, coalescing these liquids, and allowing the coalesced liquid to solidify. At the end of this process the two pieces of metal have become one continuous solid, and if the weld has been made properly, it will be as strong as the original workpieces.
