Oxyfuel Welding Fluxes

OxyFuel Welding fluxes are used to protect the metal in the joint area from this oxidation and thus let the molten filler metal flow onto clean metal surfaces. Oxyfuel welding fluxes are available as powder, paste, or rod coating. Flux powder is sprinkled over the slightly preheated joint area. The filler rod is similarly preheated and dipped … Read more

OxyFuel Welding Steel

The term “steel” may be applied to many ferrous metals which differ greatly in both chemical and physical properties. In general, they may be divided into plain carbon and alloy groups. By following the proper procedures, most steels can be successfully welded. However, parts fabricated by welding generally contain less than 0.30 percent carbon. Heat … Read more

Oxy-Fuel Welding: Vertical Position

***Oxy-fuel welding in the vertical position requires a ***technique in order to keep the molten metal from running downward. In vertical position welding, the axis of the weld is approximately vertical. When welding is done on a vertical surface, the molten metal has a tendency to run downward and pile up. A weld that is not carefully … Read more

Oxyfuel Backhand Welding

In the OxyFuel backhand welding method, the torch precedes the welding rod, as shown in figure 11-5. The torch is held at approximately a 45-degree angle from the vertical away from the direction of welding, with the flame directed at the molten puddle. The welding rod is between the flame and the molten puddle. This position … Read more
