[TheForge] Brooms and Welding Cast

[Washington, Aubrey O.]

Kenny,
That's not too much information; I'm always interested in what other people are doing.  I wish I had a buck for every cast iron sideboard socket that I've seen broken just like you describe at antique and junk stores.
 
If you Google "Welco Kast Weld 111" I'm sure you'll find a dealer somewhere.  I ordered my through Lampton Welding Supply in Oklahoma City.  They got it from one of their other stores (Kansas City, I think) that had a broken 50# package and was willing to sell in small amounts.  I didn't really need 50# of the stuff.  I think the flux was Welco 800, but some other brand might work too.  The rod was $13/lb and the flux was $15 for a 1 lb can, IIRC.
 
One problem you might run into is heating up that big chunk of cast iron hot enough to weld, without damaging the tubing.  Maybe there is a way to remove it from the brass.  If that's not possible, maybe you could fill the brass tube with water to keep if from melting while you weld.  Do you have a TIG welder?  That might work better than oxy-acet. with a #4 tip (or whatever). In either case, you will have to grind a very deep "V" to get a full penetration weld.  (Just random thoughts.)
 
Aubrey

Might I ask who sells this? I have to fix a brass bed  with a cast iron
connection for the side rails.
The cast iron is cast right on to the end of the angle iron (conical
mandrel type extrusion). The head-board has the neg
of it , which is the receiver. I'm not sure how the cast receiver is
joined to the head-board I have not explored that far yet.
one of  the H-B receivers is broken  in two, half remains on the brass
tubing H-B.
...Way to much info I'm sure..
