摘要
分析了Super304H不锈钢作为高合金耐热钢的工作环境和焊接工作重要性。采用两种化学成分有差异的焊丝YT-304H和Thermanit617对Super304H不锈钢管材进行焊接,对两种不同焊丝的施工焊接工艺和工艺控制措施进行了对比研究。针对Super304H不锈钢现场施焊过程,并通过焊接后射线底片评定工作、焊接试样性能检测的反馈情况,提出了Super304H不锈钢焊接时各环节的质量控制要点,从而提高了Super304H不锈钢现场焊口的合格率,完善了Super304H不锈钢焊接工艺措施的制定。
In order to find-out and grasp the field welding characteristics of stainless steel Super304H in field welding and installation work of tube of high-parameter boiler superheater and reheater.As a kind of high alloy heat resistant steel,the Super304H stainless steel including its work environment and the importance of its welding work are analyzed firstly.By using two kinds wire, YT-304H and Thermanit617,which chemical composition are completely difference,in welding work of Super304H stainless steel pipe,their different welding technology and welding process control measures are compared and studied.In field welding process of Super304H stainless steel,by taking advantage of the ray-photo evaluation,the welding performance and feedback of the samples,the welding quality control points and their attentions of Super304H stainless steel are proposed.Therefore, the qualification rate of welded-joints of Super304H stainless steel in field welding work could be increased.Also, the welding technology and measures of Super304H stainless steel will be developed and improved correspondingly.
