Welder Qualification Testing - ASME IX
- 1) Code & standard apply for testing:
- In this case we use: ASME IX
- 2) Witness for Welder testing:
- Each performance qualification welder testing shall be done under full supervise and control by a third party. Normally, it is Classification ( ABS / BV/ DNV-GL, LR, KR…)
- This party have to sign on welder card / welder cert after the welder pass examination.
- 3) Train The Welder For The Process To Be Qualified:
- – Welder is trained to know skill in performing the Welding Process.
- – He need have knowledge in operation of machine, precautions in storage & usage of consumable, defects in welding, their causes and remedy.
- – He practice welding in the particular position in which he is to be tested / qualified.
- 4) Testing procedure:
- Check WPS what is used for qualificaiton
- Check Essential variable for Welder testing: pls see Part 2:
- Welder qualification follow ASME IX- Part 2: Essential Variable for Welder Qualification!
- 5) Preparation Of Test Coupon:
- -QW-210 Preparation of Test Coupon
- -QW-211 base Metal
- -The basew metals may consist of their plate, pipe, or other product forms, Qualification in plate also qualifies for pipe welding and vice versa. The dimensions of the test coupon shall be sufficient the required test Specimens.
- Normally:
- – Prepare A Test Coupon Out of 300 ? 150 ? (t) mm CS Plates/pipe: min length at least 150mm
- – Angle, Root Face & Root Opening Shall Be As Per The WPS
- – Provide Run in & Run Out Coupon & Fix the Test Coupon In Any One Of The Positions To Be Qualified.
- – Weld The Groove Fully In The Position
- – All Welding Variables Shall be Strictly Within The Qualified WPS
- 6) Base metal/welding material:
- To follow WPS
- 7) Testing position:
- 8) Diameter of test coupon:
- 9) Thickness qualify:
- 10) Fillet weld test:
- 11) Acceptance criterial:
- + Visual:
- + DT or NDT
- Pls see previous part:
- Welder qualification follow ASME IX- Part 1: Genenral
- 12) Expiration and Renewal of Qualification:
- – QW-320 covers the requirements for retesting and renewing welder qualification
- – QW-322 Expiration and Renewal of Qualification:
- When the welder has not welded with the process within 6 months
- When there is a specific reason to question his ability to make welds that met the specifications
