[TheForge] Welding a whole lotta cast iron

Wed Jul 2 10:54:00 2003

Not that I 'm a pro at this cast iron stuf but the -pro's tell me you can
weld just a little bit  I guess maybe 1/2 inch or so w/ no pre heat then
peen this weld , let it cool a bit then weld another 1/2 inch and peen it I
think the peening is supposed to relieve the stress in ea. short weld, the
whole idea is that the work never gets hot. This is a time consuming
project.
