Which angle type indicates a push angle away from the weld joint?

The push angle is the correct answer because it specifically refers to the technique of directing the welding torch or gun away from the weld joint. This method is often employed to achieve deeper penetration into the base materials, allowing for a stronger weld. When using a push angle, the welder moves the torch in the same direction as the weld or towards the weld pool, which helps to control the heat and the molten metal flow effectively.

In contrast, the pull angle would imply pulling the torch towards the welder while welding, which generally results in different penetration characteristics and can lead to variations in weld quality. The drag angle describes a technique where the torch is positioned at an angle that "drags" its tip along the weld pool leading to different heat distribution. Lastly, the neutral angle maintains a perpendicular approach without pushing or pulling, which can also influence the characteristics of the weld joint.

Overall, the push angle is favored in techniques where deeper penetration and cleaner welds are desired, making it the most effective method for certain welding applications.
