 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!!!
- GRINDING is NOT allowed for removing as
 welded material, sculpting, shaping, blending
 or making repairs of any sort.
- NO GRINDING OR FILING on the final weld
is allowed, especially to blend undercut.
- 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.

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

   qualification test are
intended to determine the
  ability of welders and
welding operators to make
      sounds welds.
  DO NOT WELD OR GRIND
 ON 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.
