Important parameters of spot welding
The spot welding process includes a number of variablesthat can be adjusted in order to
achieve optimum welding performance. Tables of optimum values have been produced,
but it is also necessary to optimise the process by trial and error.
The welding currentis the current that flows through the workpiece. Of all the
parameters, it is this that has the greatest effect on strength and quality of the weld, as
the amount of heat produced is proportional to the square of the welding current. The
current must therefore be carefully adjusted: too high a current results in a weld
with poor strength, with too great a crater depression, spatter and some distortion.
