Witrynaimpulse welding. [ ′im‚pəls ′weld·iŋ] (engineering) A welding process in which two layers of thermoplastic film are heated and fused to form a welded seam by clamping … A number of techniques are used for welding of semi-finished plastic products as given below: Hot gas welding, also known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic. (Welding PVC to acrylic is an exception to this rule.)
