METHOD FOR REDUCING RESIDUAL WELDING STRESS

摘要

FIELD: construction.SUBSTANCE: invention relates to a method for reducing residual welding stress and may be used in production of welded structures. Exposure is performed by shot flow directed to welded joint surface. Exposure by shot flow is performed by lead shots with diameter of 1.75-2.75 mm with specific energy of 30-60 J/cm.EFFECT: invention increases longevity of welded articles, stability of their geometrical shapes.1 cl, 1 tbl, 1 ex
