Universal positioner for welding dwg
Welding is a fixing process where the union of two or more pieces of a material (usually metals or thermoplastics) is carried out; usually achieved through coalescence (fusion); in which the pieces are welded by melting; you can add a filler material (metal or plastic); what; when melting; forms a puddle of molten material between the pieces to be welded (the weld pool) and; when cooling; it becomes a fixed union to what is called a cord. sometimes pressure and heat are used together; or just pressure by itself; to produce welding. this is in contrast to soft soldering (in english soldering) and brazing (in english brazing); which involve the melting of a low melting point material between work pieces to form a bond between them; without melting the work pieces.
