This replica kit consists of a 5-piece set designed for training pressure piping welding inspectors and welders. The samples include: 3 "Weld-o-Let" branch connections; Sectioned socket-welded elbow; and Groove-welded pipe but joint. The discontinuities present include: Incomplete joint penetration, improper pipe retraction (in socket-welded joint), excessive root reinforcement, and porosity. Students can also measure characteristics such as fillet and groove weld size and determine their compliance in accordance with applicable standards. An interpretation sheet is included.

Pipe Weld Replica Set (PWR-1)
Three-Dimensional Training Aid Interpretation Sheet
CSC-11
1) Excessive root reinforcement; located between A and B.
2) 1/32” undercut located along weld face.
Question: Is this weld acceptable for an operating temperature of 752 deg. F and pressure of 1,010 psig?
No. It is rejectable due to weld reinforcement over 1/16”.
CSC-13
1) No pipe retraction. However, on side B there is no cracking. In this case having no pipe retraction is acceptable.
2) Side B is undercut ½” X 1/32”.
3) Measured leg = 11/64”.
Question: Does the weld at location 13B comply with Code?
It is acceptable. The smallest leg is 11/32” (0.172”) and wall thickness is 0.153”; 0.153 X 1.09 = 0.167 (the minimum required leg size). *
CSC-14
1) Insufficient penetration 1” in length.
Question: Is this weld acceptable?
No. Insufficient penetration.
CSC-15
1) Inadequate penetration 1/8”.
2) Porosity resulting from burn-through.
Question: Is this weld acceptable?
Yes.
CSC-16
1) Insufficient fill, throat.
Question: What are some problems with this weld?
There is some incomplete joint penetration and the weld is not filled out in accordance with recommended practice and manufacturers’ specifications.
* Code reference is ASME/ANSI B-31.1 for all questions.
