Abstract: 675,564. Soldering and brazing. BRITISH THOMSON-HOUSTON CO., Ltd. May 9,1949 [May 11, 1948], No. 12330/49. Class 83 (iv). Metal parts are clamped together prior to brazing by clamps made wholly of brazing metal and the assembly is heated to fuse the brazing metal and effect brazing. Clampshaped pieces 3 of brazing material are fixed to the sheet 2 by spot-welding, for example, thus holding the tubing 1 in place. The assembly is heated to fuse the pieces 3 and fillets 7 and 8 thus braze the tubing 1 to the sheet 2. The pieces 3 may be of any length and the brazing operation may be carried out without a flux if a reducing atmosphere is used.
