METHOD OF GUIDING ELECTRON-BEAM GUN BEAM ONTO JOINTED SURFACES OF WELDED PARTS Russian patent published in 2010 - IPC B23K15/00 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and can be used in fabricating whatever essential parts of gas turbine engines. Proposed method is implemented as follows. Laser head is arranged on electron-beam gun prior to welding in open atmosphere. Light beam of laser head is directed into joint of parts to be welded together. Electron beam axis is aligned with that of light beam and laser head is removed from electronic-beam gun. In welding closed surfaces, aiming elements are made on parts to be welded together and light beam is directed into joint by said aiming elements. In welding closed surfaces, aiming elements are made in the form of bench holes in jointed surfaces. Light beam is directed into each said hole to detect light beam passage through said holes using temporary plate preliminary fitted in parts joint end.

EFFECT: higher accuracy of welding.
