铸焊

Base on the weldability tests , the repair welding procedures of weari-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 maint.

通过对其焊接性能的试验研究，制定了该类铸钢件的补焊工艺：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。

Therefore,this paper introduces the repair method of large-size steel casts by sectionalized cold-junction compensation weld technology with nickel-based welding rods.

由于受到结构、外形等因素的影响，对一些大型铸件开裂采用同性热补的方法进行修复和热处理，实施困难且容易导致工件变形，为此介绍了采用镍基焊条分段冷补焊对大型铸钢件进行修复的方法。
