摘要:
为了提高管道熔化极气体保护焊(GMAW)环焊缝的性能,为现场焊接焊材选用和工艺参数制定提供指导,采用拉伸试验、冲击试验以及金相分析等方法对国内外几种气保实心焊丝在不同焊接热输入下焊缝的强度、韧性进行了试验研究。试验结果显示,焊缝金属的屈服强度和抗拉强度较焊材熔敷金属有明显提高,尤其是在较低热输入下,填充焊缝的针状铁素体更加细小。研究表明,热输入对GMAW实心焊丝形成的焊缝金属强度和韧性有较大影响,建议在匹配焊材时,应在与实际管道相近的焊接条件下进行焊材的性能复验。
Abstract:
In order to improve the performance of GMAW pipeline girth weld and provide guidance for the selection of welding materials and process parameters, the strength and toughness of several kinds of GMAW solid wires at home and abroad under different welding heat input were studied. The test results show that the yield strength and tensile strength of weld metal are obviously higher than those of deposited metal. Especially under lower heat input, the acicular ferrite of filler weld is finer. The results show that the heat input have great influence on the strength and toughness of weld metal. It is suggested that when the welding materials are matched, the welding materials and properties should be retested under the similar welding conditions of the actual pipeline.
