The professional hand extrusion welder for pipe welding and geo engineering.

Plastic extrusion is a process that allows us to mold different products. This is one of the basic processes in the production of plastics. It is also possible to weld films together with extrusion in geo engineering. In view of this, the hand-extruder booster as well as welding with the hand-tools from WELDY offer a great number of applications in the construction industry.
