In hot gas welding, the thermal energy is controlled. Heated air is fed into the work-piece and the required amount of pressure is exerted onto the wheels.
The process where the wedge is heated directly by heating cartridges. The generated heat is transferred directly onto the work-piece. This method also is suitable for thicker materials.
When Combi-wedge welding (combination of a heated wedge and hot air), preheating of the air and the actual welding process is carried out over a wedge. The preheated air also takes partial cleaning of the work-pieces.
Pendulum welding requires a welding rod similar to the base material. Both surfaces are then heated using hot air. Using an up and down, pendulum-like motion and consistent downward pressure, the two are joined.
This welding method requires the use of a speed welding nozzle. Preheat the surfaces to the appropriate temperature. The surfaces are plasticized by hot air and joined under consistent downward pressure.
In extrusion welding, the substrate is preheated with hot air and connected by adding the extrudate. The welding rod is fed into the heater barrel and the plastic is processed by the extruder screw.
