Which Arc Welding Process is the Most Efficient?

This question can be answered very quickly.  Gas Metal Arc Welding (GMAW) and Submerged Arc Welding (SAW) can have 98-99% deposition efficiency.  However, the question is a bit more complicated since when we talk about efficiency we don’t just care about deposition efficiency (how much of the electrode becomes weld metal).  What we care about […]

Is Weld Strength Affected by Shielding Gas Mix?

Can our selection of shielding gas affect the strength of a weld and other important mechanical properties?  Absolutely!  The difference is more pronounced when using flux-cored (FCAW) wires than when using mig (GMAW) wires, especially as the wire’s tensile strength goes up.   Although we can affect strength by using different gases, what we should be […]

Deposition Rate by Wire Type

A common question in the field is which wire type will provide the best deposition rate.  In one of our earlier posts “Calculating Deposition Rate for Solid Wires” we discussed deposition rates strictly for solid wires.   Here we will talk about deposition rates across wire types – mainly solid wire, metal-cored wire and flux-cored wire.   […]
