The joining of two or more pieces of thermoplastic by fusion at adjoining areas, either with or without addition of plastic from another source (such as welding rod). The term includes heat sealing, with which it is synonymous in some countries, but in the U.S. the term heat sealing is limited to film and sheeting. Welding is almost always done with two (or more) pieces of the same plastic, but it can be done with compatible plastics that melt in the same temperature range. The various welding methods are described at the entries listed below.
