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.) WebSep 27, 2024 · Gower H, Pieters R, Richardson I. Pulsed laser welding of metal-polymer sandwich materials using pulse shaping.
