TA2+16MnR复合板焊接技术在冷凝器上的应用

摘要

Against TA2 titanium in high temperature on H, O, N strong absorption effect and react with impurities such as C, Fe,Si, the characteristics of easy to produce the defects such as cracks, porosity, it analyzed the welding performance of TA2+16MnR clad plate, provided precautions and reasonable welding process in welding from several aspects, such as preparation before welding, selection of welding method and welding material, determination of welding parameters and welding sequence, and specific welding operation. The practical welding results showed the selected welding process is reasonable and welding quality is good.%针对TA2钛材在高温时对H， O和N的强烈吸收作用以及与C， Fe和Si等杂质发生反应，易产生裂纹、气孔等缺陷的特点，分析了TA2+16MnR钛钢复合板的焊接性能。并从焊前准备、焊接方法和焊接材料的选择、焊接工艺参数和焊接顺序的确定以及具体的焊接操作等方面给出了TA2+16MnR钛钢复合板焊接时的注意事项和合理的焊接工艺。实际焊接效果表明，确定的焊接工艺合理，焊接质量较好。
