It is also recommended to source different types of alloys in casting and strip/stamping form. This gives the operator a better understanding of the composition and thermal conductivity of the metals. Since close attention must be paid to the thickness or thinness, shape, and fit of the parts to be welded, operators should test-weld some parts together at different settings (voltage, pulse length, beam diameter), then cut a cross section of the piece to check the weld depth. This exercise provides the operator with a feel for the different alloys and how they react to various power levels.... (2003)
