METHOD OF BILATERAL ARC WELDING Russian patent published in 2012 - IPC B23K9/25 B23K9/167 

FIELD: welding techniques.

SUBSTANCE: method can be applied to mechanic engineering and shipbuilding for production of welded construction; one or several welding electrodes are placed on each side of the joint; the electrodes are shifted relatively one another both longitudinally for the value Ll chosen on the basis of the condition 0≤ L_l≤ 2L^max _{molten pool}, whereat L^max _{molten pool} is the maximum length of the molten pool, and transversally for the value Lt, chosen on the basis of the condition 0≤ L_t≤ 0.3B_w whereat B_w is the width of the weld; the electrodes are positioned at an angle α=15...30° to the plane of the welded parts in the area of their apex joint towards the speed of welding.

EFFECT: method allows to level down the requirements to the joint adjustment, increase the productivity and enhance the quality of the weld formation.
