GTAW, SMAW some of the important procedures are
listed below

 
1.  SS 304 to SS 304 (P8 to P8) using TIG process for root and
     subsequent passes with back purging  with argon.  Open butt  type.

2.  SS 304 to SS 304 (P8 to P8) using TIG for root and   stabilising pass and
     subsequent  passes with MMA.   Back purging for root and
     stabilising pass

3.  SS 304 to SS 304 (P8 to P8) using consumable weld  insert
     (EB type or V type) for root pass, and filler wire for stabilizing
     pass, back purging for both the passes  Subsequent passes with  TIG.
 

 
 4. SS 304 to SS 304 (P8 to P8) using consumable weld  insert for
     root and stabilizing pass with filler wire  with argon back/purging. 
     Subsequent passes with  MMA using coated electrodes.
 

 
 5.   SS 304 to SS 304 (P8 to P8) using coated electrodes by 
       MMA process.
 

 
 6.   Similarly we have got qualified  procedures for other  materials
       like CS  to CS (P1 to P1) using  different processes, different
       techniques like root with TIG  with/without inserts. Stabilising 
       passes with TIG  & subsequent passes with MMA using coated
       electrodes as per AWS E7018 or AWS E 6013. 
 

 
7.   We have done many jobs using carpenter's  Steel  (Monel 400)
      by using TIG processes.
 

 
8.   We have got qualified brazing procedures for Brass to Brass,
      SS  to MS, Brass to MS etc.
 

 9.   We have established welding procedure for welding Admirality
       brass to MS by TIG Process.
 

 10.  Our welders are qualified for welding Aluminium  pipes and
        plates.
 

 
 11.  For tube to tube sheet welding (CS to CS, CS to SS)  
        we have qualified welders approved by NPCIL.
