This article discusses different oxyfuel welding<\/a> positions such as flat, horizontal, vertical, and overhead. At the end is a small discussion on oxy-fuel forehand welding and oxy-fuel backhand welding.<\/p>\n\n\n\n OxyFuel flat position welding<\/em><\/strong> is performed from the top side of the joint. The face of the weld is horizontal in this position.<\/p>\n\n\n\n In order to deposit beads of good quality on a surface with oxyfuel process, the torch angle, motion of the torch over the surface, and position of welding flame should be maintained appropriately.<\/p>\n\n\n\n The choice of type of flame <\/a>should also be appropriate to the base metal being welded.<\/p>\n\n\n\n If narrow beads are desired, slightly raising and lowering the flame accompanied by a slight circular motion should be the approach. The tip should be positioned at an angle of 45\u00b0 with the horizontal. The flame should be pointed in the direction of welding. Refer the figures below.<\/p>\n\n\n\n If it is desired to increase the depth of penetration, the welding speed should be slowed down. A slight increase in the angle of the torch can also be adopted.<\/p>\n\n\n\n If the speed is decreased too much, the puddle size becomes too large, one should be careful to avoid a burn-through. A good bead made without filler metal appears slightly below the surface of the plate. A bead made with a filler rod<\/a> appears as a uniform buildup<\/a> on the surface.<\/p>\n\n\n\n To obtain a good weld, the puddle size should not be too large. It should be just the right size. The torch should be given a slight movement from side to side to achieve proper fusion. The bead size can be manipulated by adjusting the welding speed and also varying the amount of filler rod introduced in the flame.<\/p>\n\n\n\nOxyFuel Welding Flat Position<\/h2>\n\n\n\n
