Joint Preparations
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.
In general, surfaces being welded should be clean and free of rust, scale, dirt, grease, etc. Slag should be removed from oxy-cut sur-
faces. Typical joint designs are shown in Figure 4-19.
