Welding Guidelines (Continued)
Welding Positions
Four basic welding positions can be used; flat, horizontal, vertical, and overhead. Welding in the flat position is easier than any of the others because welding speed can be increased, the molten metal has less tendency to run, better penetration can be achieved, and the work is less fatiguing. Welding is performed with the electrode at a 45º travel angle and 45º work angle.
Other positions require different techniques such as a weaving pass, circular pass, and jogging. A higher skill level is required to complete these welds.
Overhead welding is the least desirable position as it is the most difficult and dangerous. Heat setting and electrode selection will vary depending upon the position.
All work should be performed in the flat position if possible. For specific applications, consult an arc welding handbook.
Weld Pass
Sometimes more then one pass is necessary to fill the joint. The root pass is first, followed by filler passes and the cover pass (See Figures 9 and 10). If the pieces are thick, it may be necessary to bevel the edges that are joined at a 60º angle. Remember to remove the slag before each pass.
