Welding Aluminum Extrusion. They are readily weldable in most cases with or without filler metal. The aluminum oxide from the anodized coating often floats to the surface of the weld giving it a gritty rough appearance.
Arc welding is commonly used for joining aluminium alloys. Ad Find China Manufacturers Of Aluminum Welding. Request PDF Extrusion welding in aluminium extrusion Pressure welds occur in extruded aluminium profiles either as longitudinal welds seam welds or as transverse welds charge welds.
It is possible to weld materials of differing thicknesses between 2mm and up to several centimetres thick.
This causes internal weld porosity. Aluminum extrusion profiles contain two types of extrusion welds which are seam weld longitudinal joint and charge weld transverse joint. As a resulteven aluminum extrusion seam weld line cannot be eliminated but we can change die designs and improve extrudiong processing to get more graceful finished products. If youre wondering how to weld aluminum its important to know that there are several welding processes that can be used.
