Abstract
MR. W. R. LEWIS, development officer of the Tin Research Institute, recently gave the Institution of Electronics review of the problem of soldering, particularly those aspects which have led to the continuous-belt technique of soldering articles together, or for making tin-plate boxes, when the m made of heating is with high-frequency currents generated by thermionic-valve plant. The union of metallic surfaces is greatly facilitated by previous 'tinning', that is to say, coating the juxtaposed surfaces with pure tin or a solder, either electro-lytically or by hot-dipping ; 'tinned' surfaces can be brought very close together and the space between, even if only a few thousandths of an inch, filled with solder, ingress being by capillary action. Thus the making of tin-plate boxes, in which the edges of the pieces are hooked or bumped together, entirely depends on this capillary action, using rings of solder wire, cored with the requisite flux.
