[TheForge] welding without flux

[David Seigrist]

I just saw that video about a month ago.  I believe his name is Mark Pearce
and his shop does restorative work and must forge weld without flux.  He
said the flux could leach out later causing a white streak to run down the
iron work.  It was cold enough where he was that you could clearly see him
breathing fog.  A couple of points about his forge welding:
1) the metal was upset quite a bit, even after he welded there was still a
big bulge in the bar that would have to be hammered down, 2) he took a small
shovel of hot coke and placed it on the anvil prior to welding, preheating
the anvil, 3) the scarfs to be welded were placed face down in the fire to
prevent ash or debris from getting on the faces to be welded, 4) when moving
to the anvil he did a quick slinging action to get the weld clean, 5) after
slinging off debris he rotated the metal in his right hand 180 degrees so
the scarfs were face to face on the anvil.  Steps 4 and 5 were done on the
way to the anvil with a smooth motion and focused purpose.  After the
initial weld he took it back up to welding heat a time or two to "wash" the
weld and blend in the lines.  I tried the same method on a 1/2" square bar
and it worked fine.  Your time to weld is limited so you must move with a
purpose.

Allen, I don't recall anything thing such as the color being mentioned, but
I'll try to recall the guys name and look again at the DVD.  Maybe Roger D.
remembers his name?
