a. Backhand welding, also known as drag angle, is illustrated in figure 6-41. The drag angle points backward from the direction of travel.

b. In this method, the torch precedes the welding rod, as shown in figure 6-41. The torch is held at an angle approximately 30 degrees 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 requires less transverse motion than is used in forehand welding.

c. Backhand welding is used principally for welding heavy sections because it permits the use of narrower Vā€™s at the joint. A 60 degree included angle of bevel is sufficient for a good weld. In general, there is less puddling, and less welding rod is used with this method than with the forehand method.
