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 and grease. Slag
should be removed from oxy-fuel cut surfaces. Typical joint designs are shown below.
