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.
