The ultrasonic shocking processing technology as a means of the welded metal constructions reliability and endurance increasing

摘要

The ultrasonic shocking processing technology of welding joints is developed and fatigue strength tests of different welded joints from different materials submitted to hardening ultrasonic shocking processing are carried out. It's established that application of this processing for welded joints of metal constructions submitted to alternating loadings tends to increase their operating reliability, fatigue strength and durability.
