摘要
针对(37)8 mm×1.5 mm的钛合金管板密排结构,采用电子束焊接方法进行焊接。通过采用高、低速对比焊接钛合金试板,解决了焊缝深宽比控制技术难题。通过采用电子束重复高速偏转圆扫描,解决了焊缝熔深大于2倍管壁厚的技术难题。试件按专用技术要求进行金相检测、超声波检测熔深、拉伸试验、晶间腐蚀试验、硬度测试等,各项性能均满足专用技术条件要求。
The electron beam welding （EBW） technology had been adopted for a close packing structure of Ф8mm× 1.5mm Titanium alloy tube sheet. The control of depth-to-width of weld had been solved by contrast experiment at high and low welding speed; and the process of weld penetration which should be deeper than twice the tube wall thickness also was realized. Samples were tested by metallographic analysis, ultrasonic measurement, tensile test and intergranular corrosion test according to special technical specification. The results showed that all properties of the weld met the technical requirements.
