Internal information : Purna SSK, Vasmat, Dist – Hingoli is our one of the major customer. This customer isone of the reputed customer in Marathwada & whenever we approach them with some new technology , they give us opportunity to implement it.

Procedure of reclaimation:-

1. Cleaning of surface. (Grease, oil & other extraneous material such as scale removed )

2. Using neutral flame , preheat the part & melt off drop of flux from end of rod onto beginning of joint area.

3. Continue heating until flux liquifies.4. Deposit alloy drop by drop,feeding into flame as reqd.5. Ensure that each drop bonds properly .6. Remove flux residues by washing with water .

Powder consumption:- Xuper 16 XFC – 100 gms
