Abstract
PURPOSE: To omit finishing work by forming an excellent penetration bead by using a backing material with electrical insulation property for the side and back of groove faces of base materials for electron beam welding.
CONSTITUTION: On the reverse surfaces of base materials 3 and 3', a backing material (laying copper metal powder 1 at both sides to a width of 15mm and fixing it by set box 4) with electric insulation property at both the sides centering on groove face 5 is made in contact and with welded bodies 3 and 3' grouned, a conventional welding input is increased by 10W15% to project electron beam 2 for welding. Complete fusion penetration can be obtained while lack of uneven penetration can be removed, forming an excellent and continuous penetration beads. At the same time, there is no risk of a burn through due to beam penetration. The backing material after welding can be detached easily and its finishing work can also be omitted.
