METHOD OF WELDING OF THIN-SHEET MATERIALS Russian patent published in 2017 - IPC B23K26/20 B23K28/00 

FIELD: electricity.

SUBSTANCE: influence by pulses of light radiation with a density of 103-104 W/cm² on metal thin films. The pulses of light radiation are focused on metal thin films in place of contact of two transparent rolls rotating in opposite directions. The repetition frequency of the pulses of light radiation is from 10 to 50 Hz, and the rotation speed of the rolls is chosen from the condition that from 5 to 10 pulses of light radiation emerge on the place of pressing of the metallic thin films. The device contains transparent rolls rotating in opposite directions and light radiation sources, made in the form of light-transparent flasks filled with an inert gas, with electrodes inserted through the ends of the flasks and connected to discharge high-voltage capacitors, which are equipped with reflectors that focus pulses of light radiation at the place of contact of the metallic thin films. In this case, the sources of light radiation are located inside the transparent rolls.

EFFECT: invention allows to weld the thin metal films with a width of 10 to 50 centimetres and requires the use of complex optical systems.
