某小口径低碳钢-奥氏体不锈钢复合钢管的制造项目，由于钢管口径太小，无法选择“先基层，再过渡层，最后覆层”的常规焊接工艺填充顺序，而只能考虑单面焊双面成形，即先焊接覆层，后焊接基层。通过深入研究低碳钢-奥氏体不锈钢复合板常规焊接工艺的机理，以及分析不能直接在不锈钢表面堆焊碳钢的原因，探索性地引入工业纯铁作为新型过渡层填充材料。利用纯铁含碳量低的特性，避免了焊接接头中出现晶间腐蚀、热裂纹和冷裂纹倾向等问题，其塑性、韧性好的特点也进一步克服了直接在不锈钢表面堆焊碳钢会出现的裂纹问题。通过一系列试验验证了此工艺的合理性，从而获得了一种全新的焊接小口径低碳钢-奥氏体不锈钢复合钢管的方法。
Our Company has accepted a manufacturing project to weld some low carbon-stainless steel combined tubes with small diameter. Too small as tubes were, we couldn’t make them with regular welding procedure of “base layer -transition layer -coating layer” just like common combined plates, instead, we can only weld in this order “coating layer -transition layer -base layer” to get a joint only welding from one-side. The text researched deeply the theory of welding low carbon-stainless steel combined plates, analyzed the reason why it is impossible that overlying carbon steel onto the surface of stainless steel directly, and proposed creatively industrial pure iron as a new type of transition filler metal. We made use of the character of low carbon content in pure iron to avoid the problem of intergranular corrosion, in addition, the good plastic and toughness of pure iron overcame the crack problem occurred after overlying welding carbon steel material onto stainless steel surface. We have proved the reasonability of this method by conducting a series of experiments, and gotten a new procedure to weld low carbon-stainless steel combined tubes with small diameter eventually.
