70% to passIn the illustration, the welded neck flange is attached to the pipe by a _______________. Illustration GS-0078
Adouble fillet weld only
BU-weld over a backing ring
Cplug and slot weld
DV-weld over a backing ring
AI Explanation
The correct answer is D) V-weld over a backing ring. The illustration GS-0078 shows a welded neck flange attached to a pipe, and a V-weld over a backing ring is the appropriate joining method in this case. A V-weld, which creates a V-shaped groove, is a common technique used to weld thick materials like pipe flanges. The backing ring provides support and reinforcement to the weld, ensuring a strong and reliable joint. The other options are incorrect because a double fillet weld (A) would not be suitable for a thick flange attachment, a U-weld over a backing ring (B) is not a standard welding technique, and a plug and slot weld (C) is typically used for different types of joint configurations.
