[TheForge] Fwd: Anvil repair

[James]

Not long after I posted my request for anvil repair info, I found an old 
article by Robb Gunter on the subject.  His article mirrors, pretty 
much, some of the replies here, cleaning, preheating (300 -400 F), etc.  
He uses a propane weed burner to preheat prior to repair.

Regarding the Lincoln Abrasoweld stick electrode I mentioned. These are 
really old electrodes that I've had for maybe 30 years. I called Lincoln 
Electric and was advised that this rod is the same as what they now call 
Lincoln Wearshield ABR and would be fine for this application.  It is 
limited to 2 passes however, so I will need something underneath.  The 
Lincoln tech suggested their Wearshield BU (build up) underneath, after 
cleaning.  He commented that there would be no problem welding just 
about anything into the old wrought iron base.

So, I'll practice on a rod or two to see how much deposition I get with 
the ABR.  This should give me an idea how much build up I'll need.  The 
edges of the old anvil are hammered down to about a radius equal to a 
3/4" - 1" round bar would look like.

In the FWIW dept, I snipped and pasted tech comparison of the BU/ABR 
electrodes.  It appears that didn't make it thru the robot and/or 
moderator review process.  Oh well, I wasn't trying to advertise for 
Lincoln.  The Lincoln BU rod has an as welded Rockwell of 15-28 
depending on # of passes, the ABR rod's Rockwell is 28-53 for 2 passes.  
The spec for ABR rod states it is a "good low cost abrasion and impact 
product".



Thanks guys,
