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 通過對其焊接性能的試驗研究,制定了該類鑄鋼件(磨耗板)的補焊工藝:低氫型堿性焊條,預熱與緩冷相結合的工藝措施,嚴格控制層間溫度( 250 ~ 300 )及焊接工藝規范,可獲得滿意的修復質量。
