4f

Explanation:

Identify the welding process capabilities

Using the GTAW Definition knowledge point

Gas Tungsten Arc Welding (GTAW), also known as TIG welding, is a highly versatile and precise arc welding process. Unlike some high-deposition processes that are limited by gravity in certain positions, GTAW offers exceptional control over the weld pool and can be used to weld in all positions.

Evaluate the welding positions

Using the Welding Positions knowledge point

The standard welding positions are classified for both groove welds (G) and fillet welds (F):

• 1G / 1F: Flat position
• 2G / 2F: Horizontal position
• 3G / 3F: Vertical position
• 4G / 4F: Overhead position
• 5G: Multiple position (pipe horizontal fixed)
• 6G: Multiple position (pipe inclined \(45^\circ\) fixed)

Because GTAW allows the operator independent control over the heat source (the arc) and the addition of filler metal, it is fully capable of being performed in all of these positions (1G, 2G, 3G, 4G, 5G, 6G, 1F, 2F, 3F, 4F).
