Extrusion welding is a welding procedure predominantly realized manually by using continuous fed-in additive. Components with a wall thickness up to 30 mm can be joint in one work step. The procedure is mainly used in apparatus engineering, container, and piping manufacturing, civil engineering and canalization and, building industry and groundwater protection in landfills. The following features characterize hot gas extrusion welding:
. Welding is achieved using a type and molding material alike welding
additive
. The welding additive is homogenous and entirely plasticated
. The fusion surfaces are heated with hot air to welding temperature
. The extruded mass is dispensed and pressed on with a glide shoe
. Compared to hot gas welding shorter work steps and higher density
values are achieved with high seam quality and low residual stress
With our manual extrusion welders we set new benchmarks in extrusion welding technology. The new worm gear geometry, our patented universal rod feeding system and the extensive use of light metal results in a so far unachieved productivity with the type series of manual extrusion welders. By using few components the modular design ensures a minimum of maintenance requirements. Our manual extrusion welders satisfy by highest welding performances at lowest weight.
