Abrasion resistant steel and low-carbon steel dissimilar metal consumable electrode gas shielded welding technology

The invention relates to an abrasion resistant steel and low-carbon steel dissimilar metal consumable electrode gas shielded welding technology and belongs to the technology field of dissimilar metal welding technologies. According to the technology, by the adjustment and controlling to welding positions, welding parameters, interlayer-temperature and the like, when the high-carbon and high-manganese abrasion resistant steel is welded with the low-carbon steel dissimilar metal, the purposes of preheating before welding and slow cooling after welding are achieved, so that no cracks occur in welding seams after welding is completed, the welding seams do not crack after being heated again through a heating furnace, and it is guaranteed that rolling goes on smoothly. Compared with a traditional abrasion resistant steel and low-carbon steel dissimilar metal welding technology, the abrasion resistant steel and the low-carbon steel dissimilar metal consumable electrode gas shielded welding technology has no special requirements for raw materials and equipment, so that the manufacturing cost is lowered.
