What is the common current range for GTAW on stainless steel?

• A. 10 to 50 amperes
• B. 50 to 200 amperes
• C. 200 to 300 amperes
• D. 300 to 400 amperes

Answer: (B)

The common current range for GTAW on stainless steel is typically between 50 to 200 amperes. This range is acceptable for various thicknesses of stainless steel, allowing welders to achieve sufficient heat input for proper melting and fusion without compromising the integrity of the material. In the context of stainless steel, this amperage range provides the necessary heat to create a strong, quality weld while minimizing the risk of burn-through or warping, which can occur if the current is too high. It also allows for better control over the weld pool, which is crucial in GTAW given its precision nature. Utilizing the correct amperage within this range ensures the welder can produce clean, aesthetically pleasing, and structurally sound welds, aligning with the expectations required in many industries that utilize stainless steel fabrication.
