This invention relates to the field of
submerged arc welding equipment technology and discloses a
fully automatic submerged arc welding machine, including a rotating frame, a moving
carriage, a C-shaped frame, a
welding mechanism, a feeding mechanism, and a suction device. The C-shaped frame is mounted on the moving
carriage, and an adjustment table is provided at the upper end of the C-shaped frame. A frame is provided on the adjustment table, and the
welding components of the
welding mechanism are mounted on the frame. When performing double-sided straight
seam welding on the workpiece, a straight plate protective material mechanism is installed at the end of the C-shaped frame. The straight plate protective material mechanism includes a straight plate protective material mechanism installed at the end of the C-shaped frame, which symmetrically clamps the
weld seam of the workpiece. When performing circumferential double-sided welding on the workpiece, an annular plate protective material mechanism is installed on the inner and outer sides of the joint of the two workpieces. This invention realizes
fully automatic double-sided welding operation, effectively solves the core problems such as complicated process, rapid loss of
molten pool temperature, loss of weld liquid, and poor formation, and greatly improves welding efficiency and weld formation quality. It is suitable for double-sided welding scenarios of straight seam and circumferential seam.
