FIELD: physics.
SUBSTANCE: invention is intended for butt fusion of common link of R6 mooring chain. Proposed method comprises welding machine with four electrodes. Pre-heating is carried out with intermittent fusion followed by stable continuous fusion process. Drain is performed, at the same time power is switched off after a certain period of time during settling. During settling, pressure of fixed electrodes (1), movable electrodes (2) and settling cylinder is maintained during cooling time. Weld seam (4) in joint has sufficient resistance to deformation to prevent cracking of welded port caused by annular elastic recovery.
EFFECT: method ensures production of chain links meeting the requirement of mechanical properties for R6.
