| description | The invention discloses a repair welding process for an alloy wear-resistant roller. The repair welding process is realized through five steps of oxide removal, preheating, electric arc welding, regional repair welding and cooling. After tempering treatment, components in a cladding structure are more uniform, and the precipitation number of carbide hard phases is increased. After the defect of the alloy wear-resisting roller is subjected to repair welding, the repair welding area and the range of 50 mm around the repair welding area are inspected, and the repair welding area is free of cracks, air holes and welding defects. According to the method, the welding rotating speed is 325 rpm, the welding speed is 135 mm/min, the pressing amount is controlled to be 0.5 mm, a reliable foundation is laid for improving the production efficiency, and the continuous heat preservation and oxygen isolation effects are effectively guaranteed.
本发明公开了一种合金耐磨辊补焊工艺，通过去除氧化物、预热、电弧焊接、区域补焊和冷却这五个步骤予以实现。本发明中经过回火处理后，熔覆组织中成分更均匀，碳化物硬质相析 |
