What is the 'root opening' (root gap) in a welded joint?
Answer: The separation between the members to be joined at the root of the joint
The root opening is the space between the base metal pieces at the bottom of the joint to ensure complete root penetration.
Which joint type is formed when two members overlap each other in parallel planes?
Answer: Lap joint
A lap joint is created when two workpieces overlap and are welded at their edges.
What is the 'groove angle' in a welded joint?
Answer: The total angle of the groove between the two workpieces
The groove angle is the total included angle formed by the groove faces of the two base metal pieces.
A 'root face' (land) in a groove weld joint refers to:
Answer: The flat portion at the root of a groove before welding
The root face (land) is the flat, unprepared portion at the bottom of a groove that helps control burn-through.
Which groove weld preparation is most economical for joining thin plate (under 3/16 in.) in a butt joint?
Answer: Square groove (no bevel)
A square groove (no bevel) requires no edge preparation and is most economical for thin plate where full penetration can be achieved without beveling.
The primary advantage of a double-V groove over a single-V groove for thick plate is:
Answer: It reduces the total weld volume and distortion by welding from both sides
A double-V groove reduces the amount of weld metal deposited by roughly 50% compared to a single-V, reducing distortion and cost.
