Abstract
The disclosure embraces method and apparatus for producing stream feeders for supply of streams of heat-softenable fiber forming material such as glass for attenuation into fibers. The invention sets forth an improved method for securing preformed, flanged tubular members to an orificed plate by utilization of an electron beam welding device.
Claims12
In a method of forming a stream feeder wherein a tubular member having a flange and a shank is welded to a plate, the improvement comprising:
- directing an electron beam along the peripheral edge of the flange to simultaneously contact the flange and the plate and to weld the flange to the plate in the absence of fusing the shank to the plate.
In a method of forming a feeder for producing glass fiber wherein a tubular member having a flange and a shank is welded to a plate, the improvement comprising:
- directing an electron beam at the outer peripheral edge of the flange to overlap the flange and the plate to weld the outer peripheral edge of the flange to the plate in the absence of fusing the shank to the plate to provide a visually inspectable weld.
