What more politeness do you need?

OP: this question has been asked many times but the point is that these usually depends on facility, skill, process and many other parameters. (all the 6Ms of Ishikawa diagram) so there is no definite answer.

In our factory, these are studied by the Industrial Engineering department, averaged over a time to estimate the rates.

In order, SAW, SMAW, and GTAW. If the GTAW is automated, then it will likely come in between the other 2 processes. GMAW is typically the fastest of all, though you didn't inquire about it.

Speed comes at a cost, so bear in mind that there are heat input issues to consider like distortion and the "heat treatment" of the parent alloy.
