钛合金由于具有比强高、热稳定性和热加工工艺性好及耐腐蚀等特点,在各个方面得到广泛的应用,但在焊接时不可避免产生一些缺陷,下面就如何预防钛合金焊接缺陷谈一点我的看法。1钛合金焊接脆化的预防①严格控制母材中氧、氮、氢等的含量,其中,氧的质量分数应小于0.15ㄇ,氮的质量 Titanium alloy has been widely used in all aspects because of its high specific strength, thermal stability and hot workmanship and corrosion resistance, but some defects are inevitable in welding, so how to prevent the defects of titanium alloy welding A little my opinion. 1 titanium alloy welding embrittlement prevention ① strict control of the base metal oxygen, nitrogen, hydrogen and other content, of which the mass fraction of oxygen should be less than 0.15 ㄇ, the quality of nitrogen
