BUTT WELD CONNECTION PRODUCTION METHOD WITH THE RESIDUAL TENSILE STRESSES CONCENTRATOR SET POSITION

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to the residual stressed state optimization and can be used in the welded structures production. Determining the residual welding tensile stresses concentrator position with two symmetrically located closed type isotropic points. Taking these points as the equilateral triangle vertices. Triangle third vertex is marked directly on the seam axis from that side of the concentrator, which is opposite to the concentrator movement planned direction. At the third vertex, shooting the seam through with the bullet. Hole, if the tightness is necessary, is welded or plugged with a rivet.;EFFECT: increase in the welded products durability, stability of their geometrical forms at the welded seam on the different sides therefrom.;1 cl, 1 dwg
