The writer is making perfect welds from the bot-tom of the Vd parts and finds no reinforcement is necessarywhere the sheet is welded the full thickness using a 120 In the operation of welding, the torch flame is rotated in thebottom of the Vd part, heating both sides uniformly until the. Fig. 2. metal melts and the edges are fused. Care must be exercisedso that the radius of the action of the flame is confined to thevery edges of the beveled portions. This is repeated until about2 in. of the bottom of the Vd part is fused; the stick of fluxmaterial, which is J4 in. round Swedish iron is then brought intoplay and is held adjacent to the torch flame and allowed to heatuniformly with the sheet; the distances are shown in Fig. the sheet and flux are heated to the proper amount theflux is placed against the heated sheet and the flame is movedalong the sheet slowly for the 2 in. distance, the stick of flux iA \ %m^^ Fig. 3. following the flame and melting off enough iron to cover thepreviously welded portion 1/16 in. thick. The stick of flux isthen removed for a few seconds while the burner is slowlymoved back over the added material and the edges A, Fig. 3,are smoothed over and welded to the Vd out part.
