6.10 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 Figure 6-10.
Gap varies from
1.6mm (1/16”) to 4.8mm (3/16”)
