Design of compression drive for longitudinal arc welding of thick-walled shells

Abstract
It is suggested that in longitudinal welding of a thick-walled shell a system of radial forces should be applied to the shell to avoid closing of a gap as a result of development of angular deformations. It has been found that compressive forces need to be adjusted until approximately half of the groove is filled up. Dependencies for design of the pneumohydraulic compression drive are presented, and recommendations for regulation of the compressive force are given.
Keywords: thick-walled shell, compressive force, multipass weld, angular deformations, welding device, groove preparation, pneumohydraulic drive
