钛及钛合金的焊接工艺 (一)钛及钛合金焊接工艺制订的原则从第(二)部分可焊性分析可知,为保证得到可靠的焊接质量,制订焊接钛及其合金的工艺,必须遵循下面的原则: 1.加强保护措施钛有很高的化学活泼性,在高温下(400℃以上)极易被空气(氮、氢、氧)污染而脆化,因此在焊接钛及其合金时,对焊缝及其温度超过400℃以上的区域(包括焊缝的背面),都要加强保护,绝对不
Titanium and titanium alloy welding process (a) the principle of titanium and titanium alloy welding process from Part (b) of the weldability analysis shows that, in order to ensure reliable welding quality, the development of the process of welding titanium and its alloys, we must follow The following principles: 1. Strengthen the protective measures Titanium has a very high chemical activity, at high temperatures (400 ℃ above) easily contaminated by air (nitrogen, hydrogen, oxygen) and embrittlement, so when welding titanium and its alloys , The weld and its temperature exceeds 400 ℃ above the area (including the back of the weld), should strengthen the protection, absolutely not
