STRINGER CONNECTING METHOD WITH COVERING BY BEAM WELDING AT STRINGER PANELS MANUFACTURE Russian patent published in 2017 - IPC B23K26/242 B23K15/00 

FIELD: metallurgy.

SUBSTANCE: method includes stringer installing on the collar, performed on the covering at the place of the stringer location, and its weld tack, positioning and clamping of the stringer in the welding area by means of the head with the guide rollers, stringer welding with covering collar simultaneously by two beams, directed from two opposite sides of the stringer and moving along the weld joint of the stringer. Thus the stringer welding from one side is performed by the first beam, providing weld penetration to the depth equal to 0.8-0.9 of the stringer thickness, and from the other striger side the welding by the second beam is performed, providing weld penetration to the depth equal to 0.2-0.3 of the stringer thickness. The first beam is moved in front of the second beam at the distance greater than the length of the welding bath of the first beam.

EFFECT: invention improves the quality of stringers welded joints with the increased thickness and stiffness.
