摘要
1Cr18Ni9Ti是一种应用广泛的奥氏体不锈钢。焊接后,会使接头耐蚀性明显下降,会产生晶间腐蚀和应力腐蚀开裂。分析1Cr18Ni9Ti的焊接性、食品回收管发生泄漏的原因,针对材料特点,采用焊条电弧焊补焊,通过选用合理的焊接材料、焊前准备、焊接工艺来保证焊接质量。
1Cr18Ni9Ti is a kind of austenitic stainless steel which is widely used. After welding,it can make the joint corrosion resistance decrease obviously,and mainly produces the intercrystalline corrosion and stress corrosion cracking. This article analyzes the weldability of 1Cr18Ni9Ti and the reasons for leakage of food recycling pipe. According to the characteristics of the material,adopt electrode arc welding in repair welding process ,by choosing reasonable welding materials,welding preparation and welding process so as to guarantee the welding quality.
