THERMIT PORTION PREFAB MOULDS


R.D.S.O.approved techniques for A.T. Portions and Thermit welding of rails :


Our Thermit Portions for A.T. welding of rails are approved by RDSO/Lucknow, (Ministry of Indian Railways) for manufacturing and rail welding for following techniques:

  • 52 kg.(72 UTS) with Air-petrol Pre-heating
  • 90 R (72 UTS) with Air-petrol Pre-heating
  • 52 Kg. (90 UTS) with Compressed Air-Petrol Pre-heating using three pc. Mould
  • 60 Kg. (90 UTS) with Compressed Air-Petrol Pre-heating using three pc. Mould
  • 52Kg (90 UTS) with Compressed Air-LPG Pre-heating using three pc. Mould and Auto Thimble
  • 60Kg (90 UTS) with Compressed Air-LPG Pre-heating using three pc. Mould and Auto Thimble

The hot molten metal is allowed to be poured into suitable mould encapsulating the pre-heated affected parts to be welded, thus the metallurgically bonded sound joint.

Techniques under final field trials of R.D.S.O. for A.T. Portions and Thermit welding of rails :


Our Thermit Portions for A.T. welding of rails are under final field trials by RDSO/Lucknow, (Ministry of Indian Railways) after clearance of lab evaluation and fatigue tests for manufacturing and rail welding for following techniques:

  • 52 kg.(90 UTS) with Compressed Air-LPG Pre-heating using ONE SHOT CRUCIBLE
  • 60 kg.(90 UTS) with Compressed Air-LPG Pre-heating using ONE SHOT CRUCIBL
