Abstract

The ends of the metal sheets are bent upwards at 90 degrees to form flanges, and it is necessary to weld the two top edges of the flanges to make a seal. Welding is achieved via a trolley consisting of two traverses joined by a plate (a); on plate (a) are two work cylinders, the outer end of each piston rod being located via a pivot on a second plate (b), so the plates (a, b) can be moved towards or away from each other. Each plate (a, b) is fitted with a motor driving a roller running along the flanges of the sheets being welded. At the rear of the trolley are two more rollers also running along the flanges to guide the trolley, which carries an arc welding burner fed with inert gas. Used up for welding the edges of strakes to mfr. integral tanks in ships carrying methane.
