摘要
钛材的比强度高,高温和低温力学性能好,在大多数酸、碱、盐介质中具有优良的耐腐蚀性能。但钛材的焊接性能不好,焊接中易产生氧化、氮化、气孔和裂纹等缺陷。该文对钛材焊接时易产生的缺陷做了较详细的论述和分析,并提出了较全面的防护措施。
The specific strength of titanium is high, and has a good corrosion resisting property in most mediums of acid, alkali, and salt service. But the welding property of titanium is bed, and can occur defects of oxidation, ni-trogenation, gas cavity, and fissure, etc. In this, article the defects easy occurred in titanium welding were mentioned and analyzed in detail. The comprehensive prevention was put forward.
