摘要：
Investigations of surface hardening of welded joints for various types of steel have been elongated with a help of ultrasonic impact treatment to take place of thermal one or take away the residual tensile stress. Thermal one as a traditional can be used not always due to its expensiveness and impossibility of its using for important large-sized welded productions (bridges, heavy haulers, e.t.c.) working under variable loading. Ultrasonic impact treatment coupled with ultrasonic method of assessment of the residual stress level allows processing of welded constructions by all sizes under controlled conditions. Research of structure and properties of welded joints permit to recommend the ultrasonic impact treatment as alternative to thermal one. The equipment required is offered.
