(3ee Clause 6 Qualification , 6 . 1 . 1 and 6 . 1 . 2 . 1 Prequalified Fillet Welds )
WELD3NG PROCESS �he welding shall be done by the SHIELDED METAL ARC WELDING ( SMAW) process using
Manual weldi.ng equipment . A Constant Current Welding .Power Source is required . -
WELDING E4UiPMBNT (MAC�ii&ES� All Welding and Thermal-Cutting Equipment shall be i.nspected monthly
to assure it meets the manufacturers safety requirements , and is in such condition , to enable
designated personnel to follow the Welding Procedures and attain the results of the Welding. Code .
The welding Machines shall be Certified Annually, prior to any production welding or the Welder ( s )
taking a Qualification Test . The Nlachine Certification shall i.nclude a Record of the Annual check .
The Certification shall be performed by a qualified person , authori2ed bp Management , The Record
shall include Machine No . , Brand name , Serial No . , Alternating Current ( AC ) , Di.xect Current ( DC ) ,
Constant Current ( CC ) or Constant Voltage ( CV) and a Certified recorded accuracy of a ± l � on open
Circuit voltage ( O . C . V . ) , recorded accuracy of a ± lg on Amps /Volts , Low range , Medium range and
High range , Am�s and or Volts must match Machi.ne gaqe or di,ai (Amp/Volt ) within a ± 1� tolerance ,
if not the machine gage ( s ) or dial ( s ) shall be re-calibrated in such a marm.er that the Welder or
Weldinq operator can determine the correct Amps and or Voltaqe settings , the Leads length shall
be recorded in feet , Electrode and Ground also if the Leads are coiled or uncoiled during the
Machine Certification . The person authorized to perform this certification shall , when completed,
sign; and date the record and affix his /her seal if appropriate . A copy of this Record of
Certification shall be posted on the machine and the original Record of Certification secured by
\ Management and shall be available to those authorized to use or ezamiYie them.

removed by chipping , grinding , or gouging before depasiting the ne�rt successive bead of weldinq .
PEENiHG None ; if Specitied , proceed only as specified in the fabrication document .
Note: 0°C (32°F) does not mean the ambient environmental temperature, but the temperature in the immediate
vicinity of tlae weld. The ambient environmental temperature may he below 0°C (32°F), but a heated struciure or
shelter around the area being welded could maintain the temperature adjacent to the weldment at 0°C (32°F) or
higher.
