Mounting Systems For The Welding Head-Boom mounted type
These are the most versatile type of welding systems. Normally the boom is supported by means of a column. The welding head along with carriage is mounted on to the boom and longitudinal movement is provided on the carriage. The boom itself is provided with a drive, to move in the transverse direction. Because of the X and Y movements available to this set up, they find extensive applications in longitudinal welding of internal and external surfaces of cylinders and in the manufacture of plate formed pipes and shells.
