METHOD OF ARC WELDING OR BUILDING-UP Russian patent published in 2013 - IPC B23K9/38 B23K9/04 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for reconditioning or making parts for engineering industry. Proposed method comprises making the seam along with force application to welding-building-up pool tail section. Said forced application is created by producing sound radiation from the side of forming element. Said forming element is located above welding-building-up pool tail section. Distance between forming element surface and seam surface is set such that forming seam height is reduced to required magnitude. Ultrasound concentrator is used as said forming element.

EFFECT: higher seam quantity, hence ruled out additional machining.
