This document outlines the controls for welding consumables at the Dung Quat Refinery Project. It discusses responsibilities for monitoring consumables, proper storage according to manufacturer recommendations, drying and keeping electrodes warm as specified, and issuing electrodes only with approved request slips. Welding foremen must ensure unused electrodes are returned daily and the material controller will separate for re-drying or disposal. Logs are maintained to record baking, issuing, and returns of welding materials. The goal is to provide welders with quality electrodes to achieve high quality welds and safe plant operations.

1. DUNG QUAT REFINERY
PROJECT

2. WELDING CONSUMABLE
CONTROL

3. PURPOSE
To avoid misuse of welding
electrode
To provide welders with good
condition electrode in order to get
sound weld

4. RESPONSIBILITY
 TPC’S QC – MONITOR
 SUBCON’S QC MANAGER – Audit / SUPERVISION
 SUBCON’S QC – MONITOR & SURVEYING
 WELDING MATERIAL CONTROLLER – FOR
RECEIVING, STORING, DRYING, KEEP WARM, RE-
DRYING AND ISSUING.

5. CONTROL OF STORAGE
 WELDING ELECTRODE - ORDERLY & SEPARATED WITH LABEL
 STORED ACCORDING TO THE MANUFACTURER
RECOMMENDATION
 ELECTRODE PACKAGES SHALL NOT BE OPENED UNTILL IT IS
READY FOR DRYING
 ELECTRODE / FILLER RODS SHALL BE CLEARLY IDENTIFIED
WITH EITHER NATIONAL MATERIAL SPECIFICATION OR
MANUFACTURER’S BRAND DESIGNATION.
ELECTRODE/FILLER WITH NO IDENTIFICATION SHALL NOT BE
USED

6. CONTROL OF DRYING &
KEEP WARMING
 THIS SHALL BE CARRIED OUT BY WELDING
MATERIAL CONTROLLER
 BAKING AND KEEP WARMING AS PER
SPECIFICATION OR MANUFACTURER
RECOMMENDATION

7. CONTROL OF REQUEST &
ISSUING
 ONLY AUTHORIZED QC INSPECTOR & WELDING FOREMAN
REGISTERED WITH SUBCON’S QC DEPARTMENT SHALL
AUTHORIZED TO SIGN THE WELDING REQUEST SLIP
 WELDING MATERIAL CONTROLLER SHALL NOT ISSUE ANY
WELDING ELECTRODES/ FILLERS TO WELDER WITHOUT ANY
APPROVED WELDING REQUEST SLIP.
 ALL RECORDS OF THE REQUESTING & ISSUING OF WELDING
ELECTRODES / FILLERS SHALL BE FILLED AND MAINTAINED

8. CONTROL OF REQUEST &
ISSUING
 WELDING ELECTRODE SHALL ONLY BE ISSUED TO
WELDER WITH A WORKING QUIVER (FOR STORAGE
& WARMING)
 EACH ISSUE SHALL BE LIMITED TO 3 KG PER EACH
QUIVER. ONE QUIVER IS ALLOWED TO CONTAIN
ONLY ONE TYPE OF ELECTRODE

9. CONTROL OF REQUEST &
ISSUING
 MATERIAL CONTROLLER SHALL CHECK THE
WELDING MATERIAL REQUEST FORMS FOR
QUANTITY & TYPE OF WELDING MATERIAL BEFORE
ISSUING
 ELECTRODE THAT HAVE BEEN RE-DRIED SHALL BE
ISSUED FIRST

10. CONTROL OF RETURN OF
WELDING MATERIAL
 WELDING FOREMAN SHALL ENSURE ALL QUIVER & UNUSED
ELECTRODE / FILLER RODS TO BE RETURNED TO THE
WELDING MATERIAL STORAGE AREA AT THE END OF THE
DAY
 WELDING MATERIAL CONTROLLER SHALL SEPARATE
UNUSED ELECTRODE FOR RE-DRIED OR DISPOSAL AS
REQUIRED
 ELECTRODE SHALL NOT BE RE-DRIED MORE THAN ONCE.
AFTER THE SECOND RE-DRIED, THE LEFT OVER WILL BE
DISPOSED
