During the welding, the work pieces will become hot and will tend to expand. The expansion may cause the pieces to shift from the regular position. If possible, the work pieces should be clamped into the position they are to occupy when the welding is completed.

4.3Selecting The Proper Electrode

The welding electrode is a rod, or wire, of electrically conductive metal, coated with a layer of flux.

When welding, electrical current flows between the electrode (rod) and the grounded metal work piece. The intense heat of the arc between the rod and the grounded metal melts the wire and the flux.

The rod wire joins with the base metal in the work piece to form the weld bead. The burning flux forms a gas shield around the arc and helps to control the flow of the fusing metals that form the weld bead.

The type and thickness of the metal and the position of the work piece determines the electrode type and the amount of heat needed in the welding process. Heavier and thicker metals require more heat

(amperage).

There is no hard and fast rule that determines the exact rod or heat setting required for every situation. To check the rod requirements for particular applications, refer to the rod guide on your welder, and then experiment on some scrap metal.
