Plastic welding refers to a joining method in which two plastic parts are joined into a single body by simultaneously melting the contact surfaces of the two plastic parts by heating. The prior art plastic welding techniques include hot plate welding, hot air welding, hot bar and pulse welding, etc. The hot plate welding is to melt and soften two planes to be welded by a plane electric heating plate, then quickly remove the electric heating plate, combine the two planes and apply force to the two planes for cooling. The hot air welding means that when hot air flow is directly blown to a joint area, filler wires which are made of the same material as the base material in the joint area are melted.

The flange connection adopts a mechanical method, the general flanges are made of cast iron, alloy and the like and are used for fastening plastic parts, the expansion coefficients or the contraction coefficients are different, the connection quality is low, and the cost is higher.
