摘要
针对低合金钢、铬钼钢与不锈钢的异种钢接头组织、性能相差较大 ,甚至产生裂纹等问题 ,对比焊条选用、预热、热处理对接头组织性能的影响进行了焊接试验。
In view of much difference of structure and properties of dissimilar metal weld joints of low alloy or Cr Mo and stainless steel and even bring about cracking,Comparing with the usage of different electrode and effects of preheating and treatment on structure properties of weld joint,The experiments have been carried out.
