OxyFuel Welding Forehand a. In the OxyFuel Welding forehand method, the welding rod precedes the torch. The torch is held at approximately a 45 degree angle from the vertical in the direction of welding, as shown in figure 11-4. The flame is pointed in the direction of welding and directed between the rod and the molten puddle. This position permits

In overhead welding, the metal deposited tends to drop or sag on the plate, causing the bead to have a high crown. To overcome this difficulty, the molten puddle should be kept small, and enough filler metal should be added to obtain good fusion with
Read more →Oxyfuel Welding Rods The oxyfuel welding rod, which is melted into the welded joint, plays an important part in the quality of the finished weld. Good oxyfuel welding rods are designed to permit free flowing metal which will unite readily with the base metal to produce sound, clean welds of the correct composition. Oxyfuel Welding rods are made for various
