Assembling and tack welding frames
Prepairing process for main welding after tack welding to facilitate installation of the hull shell plate. Based on a 3D blue-print, we align frames with samewidth in
Continuous welding is preformed on all frames except bulkheads based on KOMSA regulations
The wateright bulkhead is welded with glue so that the hull VOID zone can be set
Assembling the parts with tack welding technic from the head of the stern based on the marked line on separate outer plates
