Method Of Brazing Of A Special Gas Delivery System Using Fittings Having Purge Orifices
US Patent:
8196801, Jun 12, 2012
Filed:
Jul 6, 2011
Appl. No.:
13/176962
Inventors:
David J. Blaton - Quincy MA, US
International Classification:
B23K 31/02
US Classification:
228103, 228219
Abstract:
Copper purge fittings for brazing components of a special gas delivery line together are provided. An orifice is located on the top or end portion of each fitting to create a continuous flow of inert purging gas through the delivery line under construction while brazing. Each fitting will reach temperatures exceeding 1500 degrees. By having a continuous flow of inert gas while brazing, the protection of the interior portion of the system remains intact. Without a purge in place, the intense heat would create a rapid immediate buildup of carbon and other contaminates. Brazing is only commenced after the elimination of harmful oxygen and proper flow of purging gas is measured. The purging gas pressure is lowered if it becomes high enough to potentially cause separation of tubular sections from the purge fittings and is raised if a low flow rate is detected indicating potential insufficient flow of purging gas.
