AWS D1.1 Groove Welder Performance Test

Where can I find the code requirements for AWS D1.1 groove welder testing?

Tests to qualify welders are defined as “performance” tests in AWS D1.1

  • Plate Welder Testing : AWS D1.1 Part C of Clause 6 “Performance Qualification” for flat structural shapes

  • Tubular Welder Testing : AWS D1.1 Part D of Clause 10 “Performance Qualification” for tubular structural shapes

Make sure to read the entirety of Clause 6 Part C or Clause 10 Part D, to have the complete set of requirements for your application.

A welder performance qualification is the demonstration of a welder’s ability to produce welds meeting prescribed standards.

The acronym used by AWS for the documentation of a passed weld test is WPQR : Welder Performance Qualification Record. Colloquial names for the WPQR are paper, qual or qualification, cert or certification,

What should be considered for setting up the right weld test?

To determine the most effective test(s) you should consider what range of qualifications the welder needs to properly perform their daily welding tasks:

  • What range of positions are necessary for the welder to perform their work?

    • AWS D1.1 Table 6.10 : Positions qualified by Performance Plate Tests

    • AWS D1.1 Table 10.12 : Positions qualified by Performance Pipe and Box Tube Tests

  • What thickness range will the welder encounter?

    • AWS D1.1 Table 6.11 : Thickness and Diameter qualified by

    • AWS D1.1 Table 10.13 : Thickness and Diameter qualified by Pipe and Box Tube Tests

  • What welding process will the welder be using?

  • What are the essential variables for a Performance welding test?

    • AWS D1.1 Paragraph 6.20 (refers directly to Table 6.12)

    • AWS D1.1Table 6.12 : Performance Test Variable Changes that result in Requiring Requalification

      • Weld Process

      • SMAW F-Number (Applies to SMAW, but good practice for all weld processes)

      • Position

      • Diameter

      • Thickness

      • Progression (uphill or downhill) (Welders Only)

      • Backing (with or without)

      • Multiple Electrodes (Welding Operators Only)

D1.1 WPQ Essential Variables Code References Mind Map

What are some common plate weld test scenarios?

  • Limited: restricted position and thickness range, but quick - for short term or novice welders

    • Actual Values: Flat (1G) test with backing, on a 3/8” plate

    • Range Qualified: Flat position for grooves, flat + horizontal for fillets, up to 3/4” of thickness

  • Limited: limited positions & thickness range, average test time, but will cover most work

    • Actual Values: Vertical (3G) test with backing, on a 3/8” plate

    • Range Qualified: Flat, horizontal, & Vertical positions for grooves & fillets, up to 3/4” of thickness

  • Un-limited: all positions, all thickness ranges, longest amount of time, covers all plate work

    • Actual Values: Vertical (3G) + Overhead (4G) test with backing, on a 3/8” plate

    • Range Qualified: All positions for grooves and fillets, and unlimited thickness

What are the dimensions of the welder performance qualification plate materials?

  • 3/8” Plate Test : yields 3/4” Thickness range qualified for the welder

    • AWS Figure 6.20

    • Raw Coupon Pieces: 3/8” Thick plate X 3” wide X 7” long (bevel is along the 7” edge)

      • Backing: 1” wide for bend tests, or 3” wide for RT test


  • 1” Plate Test : yields Unlimited Thickness range qualified for the welder

    • AWS D1.1 Figure 6.16

    • Raw Coupon Pieces: 1” Thick plate X 3” wide X 5” long (bevel is along the 5” edge)

      • Backing: 1” wide for bend tests, or 3” wide for RT test

What inspection and testing is required for the completed weld test?

AWS D1.1 Paragraph 6.17 “Type of Qualification Tests Required”

  • Visual Inspection

    • See AWS D1.1 6.10.1 (the Performance Test uses the WPS requirements)

      • This is for the visual inspection of the finished weld (see 6.10.3.3 for bend test acceptance)

    • AWS D1.1 6.10.1.1 : Visual Inspection of Groove Welds

    • AWS D1.1 6.10.1.2 : Visual Inspection of Fillet Welds

  • Face, root, and/or side bends

    • See AWS D1.1 6.10.3.1 (the Performance Test uses the WPS requirements)

    • Root and Side Bends : see AWS D1.1 Figure 6.8

    • Side Bends : see AWS D1.1 Figure 6.9

    • Bend Test Jigs shall comply with one of the following : AWS D1.1 Figure 6.11, Figure 6.12, or Figure 6.13

    • See AWS 6.10.3.3 for the visual acceptance criteria for bend tests

    • See AWS Table 6.11 to determine how many of which type of bend tests are required

  • RT (radiography testing) in lieu of Bend Tests (Groove Welds)

    • See AWS D1.1 6.23.3 for general RT of welder performance test

    • RT Test Procedure and Technique : see AWS D1.1 6.23.3.2 and

      • RT of Plate : see AWS D1.1 Clause 8 Part E

      • RT of Tubulars : see AWS D1.1 Clause 10 Part F

    • RT Acceptance Criteria : See AWS D1.1 8.12.2, except that 8.12.2.2. shall not apply

    • RT requires a 3” backing bar with no tack welds in the area of interest

      • See AWS D1.1 Figure 6.16 Note A or 6.20 Note A & B

    • Some companies will permit RT, some will require bend tests, make sure to understand your application
