Certified Welder Welding Positions & Joint Types 2 — Questions and Answers
Question 1: Which welding position is designated as '2F' in AWS terminology?
- Flat fillet weld
- Horizontal fillet weld (Correct answer)
- Vertical fillet weld
- Overhead fillet weld
Correct answer: Horizontal fillet weld
The '2' designates horizontal position and 'F' indicates a fillet weld in AWS position nomenclature.
Question 2: In a T-joint weld, the two base metal pieces are oriented at approximately what angle to each other?
- 45 degrees
- 60 degrees
- 90 degrees (Correct answer)
- 180 degrees
Correct answer: 90 degrees
A T-joint is formed when one piece of metal meets another at a 90-degree angle, forming the shape of the letter T.
Question 3: When welding in the 4G position, the weld axis is oriented how?
- Horizontal with face up
- Vertical with horizontal axis
- Horizontal with face down (overhead) (Correct answer)
- Inclined at 45 degrees
Correct answer: Horizontal with face down (overhead)
The 4G position is an overhead groove weld where the weld face is directed downward and the welder works from below.
Question 4: Which joint type is formed when two metal pieces are placed end-to-end in the same plane?
- Corner joint
- Lap joint
- Butt joint (Correct answer)
- Edge joint
Correct answer: Butt joint
A butt joint connects two pieces of metal lying in the same plane with their edges meeting.
Question 5: What is the primary challenge of welding in the overhead (4G/4F) position?
- Maintaining consistent travel speed
- Preventing molten metal from falling due to gravity (Correct answer)
- Achieving proper preheat temperature
- Selecting the correct electrode diameter
Correct answer: Preventing molten metal from falling due to gravity
In overhead welding, gravity pulls molten weld metal away from the joint, requiring careful technique to control the weld pool.
Question 6: A corner joint is typically used when two pieces of metal meet at what configuration?
- Along their flat faces overlapping
- At their edges forming an L-shape (Correct answer)
- End-to-end in the same plane
- One piece set into a groove of another
Correct answer: At their edges forming an L-shape
A corner joint is formed at the outer or inner corner where two metal pieces meet at an angle, typically forming an L-shape.
Question 7: In pipe welding, the 5G position means the pipe is fixed with its axis in what orientation?
- Vertical (axis pointing up)
- Horizontal (axis pointing sideways) (Correct answer)
- Inclined at 45 degrees
- Flat with axis horizontal and weld rotated
Correct answer: Horizontal (axis pointing sideways)
In the 5G position, the pipe axis is horizontal and the pipe cannot be rotated, requiring the welder to weld in multiple positions around the pipe.
