Abstract

An effect of filler material composition and conditions of heat treatment on mechanical properties, the level of residual stresses, structural features and the nature of fracture of welded joints of semiproducts (sheets and plates) from near α-titanium alloy made by automatic argon tungsten-arc welding and electron-beam welding was investigated. An influence of ultrasonic impact treatment (UIT) of welded joints on LCF characteristics was analyzed. It was established that UIT provides an improvement of fatigue characteristics more than 5 times.
