WELDER BRIEFING.
GRINDING ON THE WELD TEST COUPONS NEEDS TO BE STRICTLY
LIMITED!!!!
EXCESSIVE AND PROLONGED GRINDING IS AN INDICATION THAT THE WELDER LACKS THE NECESSARY SKILL TO MAKE AN ACCEPTABLE WELD AND THIS WOULD BE JUSTIFICATION FOR
THE ATR TO TERMINATE THE WELDER’S TEST.
- You may GRIND to prep your tacks, you may GRIND a 6010 root pass, and you may GRIND starts and stops ONLY for a tie in!!!
- NO GRINDING OR FILING on the final weld is allowed, especially to blend undercut.
- GRINDING is NOT allowed for removing as welded material, sculpting, shaping, blending or making repairs of any sort.
- The WELD must be judged in the as welded condition, per UA Weld Test Specifications..
(GRINDING STARTS & STOPS OK)
(NO GRINDING ON COMPLETED WELD)
- Tolerances for mismatch can be found in the UA Weld Test Specifications.
- Angle iron for fit up is available.
- The ATR will stop the testing event due to excessive mismatch.

IS AN ESSENTIAL VARIABLE
THAT MUST BE MAINTAINED.

FINAL INSPECTION OF THE ENTIRE WELD INSIDE AND OUT
The completed test assembly shall be visually examined over the entire circumference, inside and outside, showing complete joint penetration with complete fusion of weld metal and base metal (no concavity); and shall be uniform and free of cracks, incomplete fusion, incomplete penetration, porosity, slag and undercut (not to exceed 1/32”)
Undercut is not to exceed 1/32”
- DO NOT file or grind on the completed test coupon.- DO NOT remove coupon from the holding clamp.- Power brush cleaning is allowed.
ARC MARKS OR ARC STRIKES OUTSIDE OF THE
WELD ZONE ARE NOT ACCEPTABLE!
QW-301.1 Intent of Test:
The performance qualification test are
intended to determine the ability of welders and
welding operators to make sounds welds.
DO NOT WELD OR GRINDON THE COMPFAB STANDS.USE THE CLAMP TO SECURE YOUR COUPON FOR TESTING.
- CONTINUITY IS THE WELDERS RESPONSIBILITY.
- WELDER CERTIFICATIONS EXPIRE EVERY SIX MONTHS.
- 2008 CODE CHANGES REQUIRE A CONTRACTOR REPRESENTATIVE TO SIGN OFF ON ALL CONTINUITY.
- A.T.R.’S CAN NO LONGER GRANT CONTINUITY AT THE JATT / A.T.F. WITHOUT A CONTRACTOR PRESENT. BOTH A.T.R. AND CONTRACTOR SIGNATURES ARE NEEDED.
- Filler materials and the coupon used have no bearing on the renewal of the
expired cert. - Example: By passing a UA-63, your UA-21 is renewed and you now have a new
certification.- Make your test count, do not duplicate
tests if you have the ability / skill in another process.
•KEEP SAFETY GLASSES ON AT ALL TIMES.
•SHARPEN TUNGSTEN ON APPROVED TOOLS.
•USE DRY GLOVES.
•USE FUME REMOVAL.
