Pulsed spray transfer is used to weld a wide variety of metal thicknesses.

Explanation:
Pulsed spray transfer uses a pulsed current to control heat input while keeping a stable, spray-like droplet transfer. The high peak current promotes continuous droplet transfer for strong penetration, while the lower background current lowers the average heat in the weld, helping to avoid burn-through on thin sections. Because you can tailor the pulse characteristics—peak current, background current, and pulse frequency—you can adapt the process to weld both very thin and quite thick metals. That flexibility is why this technique is used across a wide variety of thicknesses, rather than being limited to only thick or only thin metals.
