ROBOT MODULE FOR RESISTANCE SPOT WELDING Russian patent published in 2007 - IPC B23K11/10 B23K11/30 B23K101/02 B25J9/08

Abstract RU 2304498 C2

FIELD: mechanical engineering; welding.

SUBSTANCE: invention relates to resistance spot welding device for manufacture of spacer grids of nuclear reactor fuel assemblies. Provides robot module includes welding machine, industrial robot with welding gun with electrodes installed on robot arm, control system and tables with device for fastening spacer grid to be welded. Device for fastening spacer grid to be welded is made in from of multijaw chuck with jaws enclosing perimeter of said grid. Electrodes of welding guns have spherical working surface and they are provided with cylindrical connecting element. Said connecting element is arranged in electrode holder at angle to perpendicular drawn to welded surfaces. Multijaw chuck is provided with platform with reduced height sections. Slots are made on jaws enclosing perimeter of spacer grid.

EFFECT: simplified design of electrodes and method of their fastening, increased service life of electrodes.
