Abstract: The invention relates to an improved apparatus for making a circular weld on heavy thick plates in a dual torch submerged-arc welding process, the apparatus comprising symmetrically arranged dual torches disposed on a horizontal, extendible and contractible boom, the boom being supported in a vertical support member for rotation about vertical axis for a swinging movement of the boom arm, the vertical support member connected to a gear box assembly for rotational speed adjustment, a welding power supply provided in top of the gear box assembly for avoiding any twisting of welding cables, and the welding torches with flux feeding arrangement fixed on the horizontal boom with a wire reel attached on the centre of the boom.
