TIG welding process of 2205 duplex stainless steel plate

  • 摘要: 采用不同焊接参数对16 mm 厚2205双相不锈钢进行TIG多层多道焊,焊后对焊接接头显微组织和冲击韧性进行了分析研究。结果发现,2205双相不锈钢焊接接头组织为奥氏体+铁素体,多层多道焊有助于铁素体内二次奥氏体γ2的生成; 焊接接头中焊缝金属和热影响区的铁素体含量与热输入量成反比;在-40 ℃对焊接接头进行冲击试验,低韧性焊接接头的冲击断口形貌为准解理断口、高韧性焊接接头的冲击断口形貌为韧性断口,焊接接头的韧度与铁素体含量成反比。
    Abstract: 16 mm thick 2205 duplex stainless steel was welded with multipass at different welding parameters. The results showed that the welded joint of 2205 duplex stainless steel consists of austenite and ferrite, and multi pass welding results in more γ2. The content of ferrite in weld metal and heat affected zone were inversely proportional to the heat input. The impact test of the welded joints at -40 ℃ was carried out, the fracture appearances of low and high impact fracture toughness of welded joint were quasi cleavage fracture and ductile fracture, respectively. The toughness of welded joints was inversely proportional to the ferrite content.
