PURPOSE: A weaving submerged arc welding carriage having a low temperature wire feeder is provided to exclude additional spreading of welding filler by integrating a low temperature wire feeder and a welding wire weaving device in a carriage body. CONSTITUTION: A weaving submerged arc welding carriage comprises a support(10), a welding wire winding reel(14), a welding wire feed mechanism(20), a low temperature wire winding reel(18), a low temperature wire feed mechanism(22), a weaving mechanism(26), a controller(24), and a mount plate(11). The welding wire feed mechanism supplies a welding wire(12) rolled on the welding wire winding reel to a welded portion. The low temperature wire feed mechanism supplies a low temperature wire rolled on the low temperature wire winding reel into a molten pool. The weaving mechanism weaves the welding wire. The mount plate is loaded in the support.
