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 4-19.
