METHOD FOR RESISTANCE SPOT WELDING OF ROD WITH PLATE Russian patent published in 2009 - IPC B23K11/14

Abstract RU 2352441 C1

FIELD: technological processes.

SUBSTANCE: diameter of hole in plate is set as not more than rod diameter by 0.20 mm. Prior to passage of the main current pulse, heating pulse is passed with current value of 0.6-0.7 from main pulse current and duration of 0.6-0.8 s. Value of main pulse current is selected in the range of (1.2-1.3)I₀, where I₀ is value of current pulse during welding of packet from two sheets with total thickness equal to plate thickness.

EFFECT: reliable fixation of parts from composite materials.
