- Code: AWS D1.1 (Structural Welding Code – Steel)
- Process: SMAW (Shielded Metal Arc Welding)
- Welding Procedure: SMAW-U-WPS
- Electrode: E7018, 1/8″ diameter
- Material: 3/8″ thick ASTM A36 Steel Plate
- Dimensions: 3” x 6” with 22.5° bevel
- Position(s): 3G (Vertical) or 4G (Overhead)
Acceptance Criteria (Visual Examination)
Each test plate must meet the requirements specified in AWS D1.1 Section 4.22.1:
- The weld shall be free of cracks
- All craters shall be filled to the full cross section of the weld
- The face of the weld shall be flush with the surface of the base metal (undercut shall not exceed 1/32” and weld reinforcement shall not exceed 1/8”)
- Test plates shall be free from arc strikes
Acceptance Criteria (Mechanical Testing)
Two test specimens will be cut from each test plate. All specimens will then be bent in a bend jig.
For acceptance, the convex surface of the resulting U-shape must not contain any defects exceeding the dimensions specified in AWS D1.1 Section 4.22.5:
- 1/8” maximum dimension for a single discontinuity
- The maximum sum for all discontinuities shall be equal to or less than 3/8”
