铸铁件在制造过程中发现的铸造缺陷,绝大部分是可补焊的。铸造车间一般均设有补焊工段或小组并配备相应的设备和场地。在使用部门也时常遇到裂损或磨损的铸铁件需要补焊修复。修复铸铁件,特别是大型铸铁件的缺陷,裂损或导轨面的研伤等,具有十分显著的经济效果。以往的一些印象中,铸铁件比较难焊。但是,随着己定型生产各种铸铁焊条和其他铸铁焊接材料,随着不断总结、交流有关铸铁补焊的技术经验,铸铁补焊正在成为被广泛掌握的技术,铸铁己逐渐进入易焊材料的行列。 Cast iron found in the manufacturing process foundry defects, the vast majority of repairable welding. Casting workshops are generally equipped with repair sections or groups and equipped with the appropriate equipment and venues. In the use of the department are also often encountered cracked or worn cast iron pieces need repair welding repair. Repair of cast iron parts, especially large cast iron defects, crack or rail surface injury, etc., has a very significant economic effect. Some of the past impression, cast iron parts more difficult to weld. However, with the continuous production of various cast iron welding rods and other cast iron welding materials, the continuous casting and repairing of cast iron is becoming a widely-held technology as it continues to summarize and exchange technical know-how of cast iron repair welding. Cast iron has gradually entered the easily weldable material Ranks.
