摘要
阐明了白口铸铁轧辊补焊的特殊性,从工艺上实现了有效降低焊接热应力并使母材与熔敷金属良好熔合。在试验研究基础上,设计出大型白口铸铁件补焊新工艺,并成功地用于生产。
The partioularity of repair welding for white iron roller is explained in the paper. The fine coalesoence at fusion face between base metal and welded metal has been obtained and thermal stress reduced effectively through adjustment of procedure parameters in welding. On the base of expe rimental result,a new procedure for repair white iron castings with large thikness has been designed and applied successfully.
