Purpose The purpose of this procedure is to have effective control of welding consumables for timely availability as well as to meet quality requirements of the weldment.
2.
Scope The scope of this procedure covers estimation of welding consumables, raising PR for procurement action, checking welding consumables at CMC stores on receipt, approval of
welding consumables
for
issue and issue
of welding consumables to the
contractor(s). This procedure is applicable for all construction activities carried out at Jamnagar.

Methodology
6.1
Estimation of welding consumables, PR raising & verification of TCs :
1 6.1.1 WTG estimates welding consumables on receipt of Job scope, scope of welding automation and “EPCMD-2-QM00-JEP-ME-029 Reconciliation of Welding Consumables & Associated Consumables for Piping & Structure”. After checking the existing stock level, WTG raises PR for meeting additional quantity requirements, if any. 6.1.2 After PR approval, WTG approaches Purchase department with reference to approved PR, latest revision of “Procedure for approval of welding electrodes, filler wires & fluxes manufacturers (EPCMD-2-QM00-JEP-ME-021)” and “Technical supply conditions of welding electrodes, filler wires and fluxes (EPCMD-2QM00 TCR ME013)” to facilitate procurement in time. Procurement group is raising PO accordingly. 6.1.3 After receipt of welding consumables at CMC stores, CMC verifies item, quantity and co-relates with the P.O. Also AWS class, brand name, manufacturer, size, batch number and condition of welding consumables is checked by QMD at CMC in line with TC and technical supply conditions. In case co-relation is not established/ condition does not fulfill requirements, matter is highlighted to WTG as well as procurement. 6.1.4 For CS and LTCS welding consumables, TCs are reviewed by WTG for checking technical correctness. Whereas for LAS/SS/non ferrous welding consumables, over and above TC review, PMI is carried out on every batch for positive identification of the material. When TC as well as PMI results meet the requirement, CMC is informed to take the material into stock. Wherever result does not comply with the requirements, the same is rejected immediately and highlighted to procurement group. The supply having discrepancy is kept under quarantine and such welding consumables are not issued. Over and above, whenever there is reason to raise doubt against vendor’s supply, any additional test is carried out, depending on type of consumable.
6.2
Storage of welding consumables : Following guidelines have been given to CMC which can be reinforced from time to time for effective storage:
6.2.1 Welding consumables must be stored in their original packing in a dry place adequately protected from the effects of weather and in accordance with the manufacturer's recommendations. For all consumables, the usage principle valid is: First-In FirstOut. 6.2.2 Welding consumables will be stored as per classification, size, batch number and brand name with proper identification tags to facilitate retrieval. 6.2.3 When stored, SMAW electrodes will be stacked as shipped or as per the specific manufacturer's recommendations. 6.2.4 Filler wire used must be properly stored to avoid damage and rust. They should be kept in their original bundle or package. 6.2.5 Flux supply is made normally in bags with polyethylene inner lining and should be stored as supplied.

Reliance 6.3
Issue of welding consumables from CMC : Following is the present approach for issuance of welding consumables:
6.3.1 Material withdrawal request is prepared by contractor & recommended by Construction Manager for issuing the quantity. The welding consumable required is verified by field – QMD and approved by WTG. 6.3.2 Based on the approved request, MIN is issued by respective material coordinator. Based on approved MIN, CMC issues the welding consumables.
7. 1
Discrepancy Handling Any non conformance related to welding consumables at field is reported to WTG for necessary action.
