Which of the following describes the recommended settings for tungsten in GTAW on stainless steel?

When performing Gas Tungsten Arc Welding (GTAW) on stainless steel, the recommended setting for the tungsten electrode involves creating a pointed tip. This sharp point is crucial as it helps to concentrate the arc and achieve a precise and focused weld. A pointed tungsten electrode allows for better control of heat input, which is important because stainless steel is sensitive to excessive heat. Thus, using a low current setting is appropriate to prevent warping and burning through the material, ensuring that the integrity of the weld is maintained.

For stainless steel, the combination of a pointed tungsten electrode and a low current helps achieve a stable arc while minimizing the risk of overheating the thin material, which is common in stainless steel applications. This approach allows for clean, strong welds and supports the unique mechanical and aesthetic qualities desired in stainless steel fabrication.
