10.3 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
surfaces. Typical joint designs are shown in the following figures.
