EXTRUSION WELDING

Extrusion welding is the most versatile method of jointing. In this procedure, welding rod (which is manufactured from the same raw material as AKS) is drawn into the extrusion machine, melted and extruded onto the overlap of the AKS sheets to form a welded bridge across the two sheets.

The mobility of the equipment makes this method ideal for on-site welding and it is the only welding  method that can be used to join sheets after they have been cast into the concrete.
