A small portion of rail was broken at the expansion join area and it was very difficult
to take a decision for the department to go for weld or to change the rail. Changing
of rail is always suggestable but we have assured them that we can weld even this
small portion of rail with our Magna – 303 electrode. So we repaired the same with
Magna – 303 electrode and is running successfully till date.

This track was subject to heavy traffic as the billets from CC(Continuous
Casting) being transferred to Rolling Mill. The repair of this track involves changing of complete
track and also the concreting job at site. So the idea was evolved that if the broken piece could
be welded in- situ condition, lot of time and cost could be saved. So we took up this challenge
and welded the broken portion with Magna – 303 Gold Electrode in-situ condition.
- 6. Electrode Used:
Magna – 303 , 3.96mm, Qty – 2 Kg
Magna – 100, 3.96mm, Qty – 1 Kg
- 7. Welding Procedure and Parameters used.
The broken portion was placed in its position and tag welding was done. The job was pre-heated
up to 1500 C and interpass temperature was maintained throughout the execution of the welding.
Every pass was pinned properly except the root run. After completion of the job, the welded portion
was hammered till the hammer starts bouncing.
- Benefits experienced by customer.–
A lot of cost was saved by avoiding complete change of Rail and Concreting Job at site.
The broken piece of Rail welded with Magna electrode near WRM canteen is running successfully
for last one month. We have not faced any problem there after this welding. This welding of Rail
with this electrode has helped us to eliminate the replacement of complete Rail along with concreting
job at the site. It has saved total down time of 10 hrs.
We appreciate your team's effort of welding job.
