Inconel600合金封头拼接成型技术

Process of welding technique on Inconel600 alloy

制造再生器用Inconel600合金焊接时,液态金属流动性差、焊缝金属熔深浅,易产生各种焊接缺陷;其焊接接头的力学性能和耐蚀性取决于能否正确选用焊接材料、严格控制焊接热输入量以及制定合理的焊接工艺。结合丙烯装置再生器用Inconel600的焊接和结构特点,采用焊条电弧焊拼接后整体成形技术,进行了焊接工艺试验和产品施焊,表明所选用的焊接方法、焊接材料、焊接工艺以及热处理规范正确合理。

The welding of Incone1600 alloy on propylene operation,because of the fluidity of liquid metal is bad、the penetration of weld metal is narrow,it can cause all kinds of welding defeats.Whether the joints has good mechanical properties and the ability of corrosion resistance is determined by correctly chosen welding materials,strictly controlled welding heat input and reasonable welding procedure parameters.The article combines Inconel600 alloy＇s welding features and the operation＇s structure features,finished SMAW WPQ,all the technical specifications are satisfied.This proves the chosen welding process、welding materials,welding and heat treatment procedure parameters is correct and reasonable.
