Certified Welder Welding Positions and Joints 2

Question 1

Which welding position is designated as '2F' in AWS terminology?

Accepted Answer

Horizontal fillet weld

Answer

The '2F' designation refers to a horizontal fillet weld, where the weld axis is horizontal and the face is vertical.

Question 2

What is the primary challenge when welding in the 4G (overhead groove) position?

Accepted Answer

Molten metal falling due to gravity

Answer

In the overhead position, gravity pulls molten metal downward away from the joint, making it difficult to maintain a proper weld puddle.

Question 3

A T-joint is formed when two pieces of base metal are joined at approximately what angle?

Accepted Answer

90 degrees

Answer

A T-joint is created when one piece of metal is perpendicular (90 degrees) to another, resembling the letter 'T'.

Question 4

Which joint type provides the greatest strength for joining two plates end-to-end under tensile loading?

Accepted Answer

Butt joint with full penetration

Answer

A full penetration butt joint provides the highest tensile strength because the weld metal completely fills the joint and is continuous through the full thickness.

Question 5

In the 3G welding position, in which direction is the weld typically progressed?

Accepted Answer

Uphill or downhill vertically

Answer

The 3G position is a vertical groove weld, and the welder progresses either uphill (3G-up) or downhill (3G-down) along the vertical joint.
