Abstract

686,120. Soldering. DU BOIS CO., Ltd. March 16, 1951 [March 16, 1950], No. 6654/50. Class 83 (iv). In a flux cored solder the bore is of non- circular cross-section having a plurality of longitudinally extending recesses radiating from its centre towards the outer surface of the solder, the width of at least one of the recesses increases over at least a part of the depth of the recess outwardly from the bore centre and the thickness of the solder tube wall is less over the ends of the recesses than it is at places between the recesses. In an embodiment, a cylindrical solder tube 1, Fig. 1, has a clover leaf shaped flux core 2 but two or more than three recesses 3 may be employed. In another embodiment a solder tube 31, Fig. 4, has a bore with four recesses 33 filled with flux, the sides 34 of which are convex and the tops 35 of which are concave. This construction may be modified by employ. ing a straight instead of a concave top. In a modification a solder stick has a flux core of Maltese Cross section with straight sides and ends to the arms while a further modification shows three recesses, the sides being straight and the ends concave. The external surface of the solder may be triangular, square, &c., or may take a section the same as that of the core or may be formed with flutes or grooves in the spaces between the recesses. The core may contain flux mixed with powdered solder so that flux total solder quantity is 1¢-3 per cent. Specifications 605,110 and 636,030 are referred to.
