[TheForge] Anvil Repair - 7018 Rod use

[dan tull]

Why are you using 7018?

It's a low Hydrogen rod used by pipe and tank welders that have to have 
x-ray/magnaflux. Soon as you open the can, it starts absorbing and ruining. 
That's why they throw away partial boxes at the end of the day.  The 70XX is 
stronger(harder??) than 60XX only in tension.Anvil pounding is compression.

Why don't you look at MG750 rod. It was created for repair for the ROCK 
CRUSHING industry.
HIGHEST IMPACT rod. Not abrasaweld that just grinds off hard. Extra benefit: 
NO pre-post heating. DUH! Plus it is excellent for welding dis-similar 
carbon steels(as in mild hardy tangs to high carbon tools).  Lay a base w/ a 
6011 "plunge" rod to tie face to body, and lay MG750 over. Hint : watch out 
for popping slag as your weld cools.

Expensive? $2/stick, so split a box w/ another smith.

I have patched up many anvils in 24 yrs, and have not had a failure w/ this 
rod.
And I don't own stock in MG.
