Important Basis

The effects of multiple repairing-weld and TIG-dressing on the fatigue property of high strength steel weld joints used in platform have been investigated. Through the fatigue tests on high strength steel welded joint samples, the life estimating formula is obtained after each time of repairing weld and TIG-dressing. The S-N curve and the equation after repairing weld and TIG-dressing are given. The work in this paper offers an important basis for the multiple repairing-weld of platforms.

Multiple Processing

The effectiveness of multiple hardening by shot peening of samples made of «30ХГСН2А» high-strength steel to increase their fatigue strength is experimentally established. Repeated hardenings allow not only to restore the original durability and even significantly increase it. Keywords fatigue strength, durability, resource recovery, multiple processing by shot peening, repeated hardening, high-strength steel. [email protected]
