Joint Preparation
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
1-19.
