Metal transfer in metal cored wires can be in any of the three modes — short circuiting, globular or
spray, depending on the welding parameters and shielding gas (Figure 4.29). In practice, spray mode
is used most often. For out of position applications pulsed spray transfer can be used.
The cored wire designation schemes followed in CSA Standard W48-01 and in AWS Specification
A5.20 for classification purposes are shown in Figures 4.30(a) and 4.30(b), respectively.
