Multiple Choice

In the 2G position, which metal transfer mode is associated with FCAW fill passes and cap?

Globular transfer is the mode that best fits FCAW fill passes and the cap in the 2G (horizontal groove) position. In FCAW, globular transfer uses larger metal droplets that are deposited into the weld pool in a relatively forgiving, steady manner, which is ideal for building up weld metal across a horizontal joint. The flux core and the resulting slag help protect the bead and help shape the cap as you progress, making it easier to achieve a good bead profile in a horizontal weld. Spray or pulsed spray transfers involve many small droplets and higher energy, which can lead to deeper penetration and less control for fill passes in a horizontal position. Short-circuit transfer can be easy to control but tends to produce a different bead character and is less typical for the heavier deposition required in fill passes and cap with FCAW.
