DOUBLE HOT WEDGE WELDING

This method is used to prefabricate large panels on-site, prior to installation. In this process, two sheets are overlapped approximately 50mm and a hot wedge moves between the overlap, heating the AKS sheets.

Two rollers then press the heated material together, forming two parallel welds separated by a small test channel. This is the fastest method of on-site welding and it also greatly simplifies the joint testing process.
