WELDING OPERATIONS I - OD1651 - LESSON 1/TASK 2
with an oxygen cutting torch, it is necessary to use an
oxidizable steel rod.
The oxygen combines with metal from the
steel rod creating high temperature drops of molten steel. These
drops of molten steel wash off onto the weld and help melt the
stainless steel weld. This washing action is accomplished by an
oscillating motion of the torch tip which causes the molten weld
metal to wash away in thin layers.
When thick stainless steel
welds are cut, the steel rod should be held against the side of
the weld and fed downward slowly to generate the high temperature
required to create the molten steel into drops.
The cutting
process using a steel rod is illustrated in figure 25.
