Material properties of the components being welded, hot gas temperature, size of the weld rod, and technique utilized all influence the weld travel speed. Due to the manual nature of hot gas welding, this process is typically slower than other thermoplastic welding methods. Higher weld travel speed can be obtained using a speed tip.
[Thermoplastic welding will normally use weld pressures between 72.5 psi and 290 psi. [ 3 ] Welding pressure is a parameter determined by the size and area of the part being welded, larger parts require higher pressures to reach the required amount of part upset.
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 ...
Ultrasonics welding is one of the most commonly used technique for welding advanced thermoplastic composites. This is due for its ability to maintain high weld strength, hermetic sealing, and high production rates. This welding technique operates at high vibrational frequencies (10–70 kHz) [2] and low amplitude. The direction of vibration is ...
Implant induction welding is a joining method used in plastic manufacturing. The welding process uses an induction coil to excite and heat electromagnetically susceptible material at the joint interface and melt the thermoplastic. The susceptible material can be contained in a gasket placed between the welding surface, or within the actual ...
