Page 8: Know Your Welder
When reactive metals are exposed to air they form an oxide layer that KNOW YOUR WELDER insulates the base metal and prevents welding current flowing, it also contaminates the weld area. Reverse current flow is required to break through/ clean off this oxide layer so that welding can take place, while the current flow during the positive cycle does the majority of the heating of the weld pool area. -

Flat Position, Down Hand Butt Weld (Fig 1-11) MMA WELDING GUIDE MMA (STICK) BASIC WELDING TECHNIQUES Size of Electrode The electrode size is determined by the thickness of metals being joined and can also be governed by the type of welding machine available. Small welding machines will only provide current (amperage) to run smaller sized electrodes. - Page 12 Joint Preparations Corner Weld (Fig 1-19g) In many cases, it will be possible to weld steel sections without any special preparation. For heavier sections and for repair work on castings, etc., it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetration of the weld metal and to produce sound joints.

- Page 14 B. Fillet Welds Multi Run Vertical Fillet Weld (Fig 1-26) These are welds of approximately triangular cross-section made by depositing metal in the corner of two faces meeting at right angles. Refer to Figure 1-14, 1-23 and 1-24. A piece of angle iron is a suitable specimen with which to begin, or two lengths of strip steel may be tacked together at right angles.
