METHOD OF BUTT LOCKING OF DIFFERENT-THICKNESS PARTS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to welding, particularly, to electron beam welding vacuum of different-thickness parts. Said butt locking joint is made between large-depth part, lock base being made at weld edge end, and smaller-depth part to be jointed thereto. Note here that lock base is skewed at 45°???60°, while welding is effected with butt penetration through entire depth. Lock base can be skewed straightly or in zigzag manner.EFFECT: higher quality of seam.3 cl, 6 dwg
