Enclosed herewith is a small writeup (attachment) on Welding of Cast irons and Copper alloys which talks about selection of consumables.
Trust it will benefit you.
As you start working on these alloys you will gain more experience...
Also i suggest that you should refer Product Handbook of any Maintenance & Repair Consumable manufacturer for the selection of correct consumables / procedure for your application.
If you are in India then call me on my cell.

>Hi Prem
Many thanks for your reply. I have already consulted these documents.
But there is only a standard composition against each electrode coding
but unfortunately there is no selection criteria of electrodes for
Brasses,Bronzes and Cast Iron. For example in some applications we use
an electrode that gives the deposit of 60% Ni and rest of Fe for Cast
Iron Welding where as sometimes we use the electrode that gives 55% Ni
for the same kind of applications and sometimes we use an electrode
that gives 99.99% Ni. But I dont know the selection criteria. I mean
why dont we use an electrode that gives exactly the Cast Iron
composition. Same is the case with Brasses and Bronzes. I hope that I
have explained my problem.
