Certified Welder Welding Positions & Joint Types 3

Question 1

Which groove weld joint preparation involves beveling only one piece of the base metal?

Accepted Answer

Single-bevel groove

Answer

A single-bevel groove joint has only one piece beveled, resulting in an asymmetric joint preparation.

Question 2

What does the term 'weld progression' refer to in vertical welding?

Accepted Answer

Whether welding moves upward or downward

Answer

Weld progression in vertical welding refers to the direction of travel — either uphill (vertical-up) or downhill (vertical-down).

Question 3

An edge joint weld is most commonly used for which application?

Accepted Answer

Thin sheet metal where edges are parallel and close together

Answer

Edge joints are used primarily for thin sheet metal where two parallel plates have their edges joined, often in flanged applications.

Question 4

In the AWS position designation '3G', what does the '3' indicate?

Accepted Answer

Vertical position

Answer

In AWS nomenclature, the number 3 designates the vertical position, so 3G means a vertical groove weld.

Question 5

Which factor most affects the choice between vertical-up and vertical-down welding?

Accepted Answer

Material thickness and process type

Answer

Material thickness and welding process primarily determine progression direction — thicker materials benefit from vertical-up for better penetration while thin materials use vertical-down.
