The welding performance of homemade wear - resistant cast steel has been studied base on the weldability tests , the repair welding procedures of wean - resistant cast steel ( abrasion - plates ) have been made up , the results show that satisfying repair welding quality can be attained with such welding conditions as the low hydrogenous alkalescent welding rod , preheating and slow cooling , strictly maintaining the interbedded temperature of 250 ~ 300 and controlling welding technique 通过对其焊接性能的试验研究，制定了该类铸钢件（磨耗板）的补焊工艺：低氢型碱性焊条，预热与缓冷相结合的工艺措施，严格控制层间温度( 250 ~ 300 )及焊接工艺规范，可获得满意的修复质量。
