1.        INTRODUCTION
                                           1
          Depending on contract conditions, welding consumable and other associated consumable are
          being issued free of cost to many a contractors. In order to reconcile the items, one standard
          reconciliation norm of the company becomes necessary to avoid individual approach.
2.        PURPOSE              1
          Purpose of this document is to provide outline for having a unique approach for certifying the
          consumption of welding consumable and other associated consumable supplied to contractors
          as free issue items. The procedure covers the methodology of consumption certification and
          norms of consumption derived based on practical experience.
3.        SCOPE          1
          Present scope of consumption norms cover welding electrodes, filler wires and flux used in
          GTAW(TIG), SMAW(MMAW), FCAW, SAW process for piping and structural work.
          Consumption of argon gas, dissolved acetylene, oxygen and grinding wheels are also covered
          under the present scope under associated consumable part.
          The scope of this procedure is applicable only to all concerned working in REAL, Jamnagar
          Complex, wherever Welding & Associated consumable are issued as free issue items.

8.        PROCEDURE
8.1       WELDING ELECTRODES/FILLER WIRES/FLUX
      -     The norms for welding consumables have been developed & Issued by QMD with inputs
            from Fabrication Division welding Team.
      -     All contractors shall submit consumption of all welding consumable & associated
            consumable against the executed work quantities along with final bill. Final
            reconciliation of the total scope of work shall be submitted and certified by EIC/QMD
            during the closure of Work Order.
8.2 DEVIATIONS
          The consumption shall be calculated based on the billing quantities and the norms as above
          with the following deviation.
                                                                     2
(A)       Deviations due to welding process (Carbon Steel).
- E6010+E7018+SAW
      As application of SAW process is limited to Fabrication Shops only, consumption of flux & wires
      of SAW shall be verified based on the statement of the contractor’s statement duly certified by the
      shop welding team.
      Consumption of FCAW will be verified based on the statement given by contractors and certified
      by shop welding team/QMD Engineer for fieldwork.
      Based on the consumption of FCAW, SAW wire, equivalent inch dia work shall be calculated.
      This will be subtracted from total inch dia. The subtraction value will be treated as welding work in
      SMAW. From norms, consumption in SMAW consumable shall be calculated which will be
      compared with actual consumption of SMAW electrode. Accordingly consumption shall be
      certified.
         All quantity for the above works shall be checked and certified by shop/site production
         engineer.
(D)      Based on the consumption statement and proper justification submitted by contractor,
         EIC may accept deviation from the norms for exceptional cases on case-to-case basis.
(A)      The billing data available in contractor bills are for ranges of thickness.
       - (i.e.) up to 10 mm.
       - 10-12mm,
       - 12-15mm,
       - 15-19mm,
       - 19-24mm,
       - 24-30mm,
       - 30-25mm, etc.
      For consumption certification purpose,:
       - 8mm thickness shall be considered for the first range, i.e. up to 10mm thickness.
       - For other cases, average thickness within the range shall be taken.
           A separate matrix has been enclosed as Annexure-IV with the W.O. item code for the ease of
           certification
    (B)     For consumption calculation, the following joint configurations combinations is neglected for
            pipe wall thickness of 22 mm and greater
           - Single bevel V pipe joint to compound bevel fitting
           - Fitting to fitting joint of compound groove
            Based on the present procedure, the consumption will be treated as it in all the cases.
            The reconciliation statements prepared by shop welding engineer/site engineer shall be
            discussed with the contractors for any major deviations. After the initial two-month, contractors
            shall be advised to prepare reconciliation statements totally on the same basis and submit for
            checking and approved.
    9.      NORMS
            Following are the norms for welding consumable:
      -     For groove welding root pass in GTAW process, consumption of filler wire is considered as
            21gm/inch dia for root pass only. Wherever root and hot pass welding is carried out with
            GTAW process, consumption of filler wire shall be taken as 42gm/inch dia.
      -     For fillet welding root pass in GTAW process, consumption of filler wire is considered as
            144gm/meter for root pass only.
      This consumption is estimated for Carbon Steel, Low Alloy Steels and stainless steels. For the
      estimation of Nickel and Nickel based alloys (Monel, Inconel etc), a factor of 1.12 shall be
      multiplied with the final weight of welding consumable to compensate the mass density
      difference.
          c) Pipe Supports
          Saddle supports-Reconciliation of welding consumable shall be carried out based on the weld
          length for saddle supports. For other supports, reconciliation shall be carried out on the weight
          of the supports in the light weight structure category.
9.3.1 Piping
      The basis for calculation considered are :
       -    Pipe Shop’s actual consumption
       -    Craft Training Centre’s experimental data
       -    A contractor’s site actual consumption
       -    50 % added as wastage at sites .
       -    Requirement of dissolved acetylene and oxygen gases are not considered for stainless steels
            and LAS steels of 5 Cr - 0.5 Mo / 9 Cr – 1 Mo / 9 Cr – 1 Mo ( Modified Steel )
       -    Requirement of dissolved acetylene and oxygen gases are not considered for pipes and
            fittings supplied in machined condition.
Consumption of DA and Oxygen as per item code has been derived and enclosed as Annexure-VI
