摘要:
分析了超纯铁素体不锈钢的焊接性,概括了汽车排气系统不锈钢管常用的焊接方法和焊接工艺。分析认为,超纯铁素体不锈钢焊接时的主要问题是焊接接头易产生晶间腐蚀和脆化,用超纯铁素体不锈钢制造汽车排气管,需要选择能量集中、热输入小、保护效果好的焊接方法和焊接参数。主要焊接方法有钨极氩弧焊、激光焊、高频焊和等离子弧焊。此外,组合焊接技术尤其是激光与其他热源复合加热的铁素体不锈钢管焊接研究等,是汽车排气管先进焊接方法的发展方向。
Abstract:
In this article, the weldability of ultra-pure ferrite stainless steel was analyzed, the welding methods and technologies which were commonly used on the stainless steel pipes for automotive exhaust system were summarized. The results indicated that the main problems which appear in welding of ultra-pure ferrite stainless steel are the intercrystalline corrosion and embrittlement in the welded joints. It should select some welding methods and welding parameters with the characteristics of energy concentration, low-heat input and good protective effect, such as argon tungsten arc welding, laser welding, high frequency welding and plasma arc welding to produce automotive exhaust system using ultra-pure ferrite stainless steel. In addition, the composite welding technologies are the developing direction of advanced welding methods used for automotive exhaust pipes, especially for the research on compound heating welding ferrite stainless steel pipes by laser and other heat sources.
