Why two forges

Why is it that some makers use a seperate beefed up forge for welding? Is it because the corossive action from the flux, the higher temp required or what.
 
Both. And size matters too, expecially if your forging forge only heats about a 4" section at a time.

Usually it is difficult to ramp back a welding forge. In my experience you get a lot of blow back and you need to keep it roaring. I did some modifications to my forge burner tube and i can turn it back till it just barely keeps the walls red. I have not put in the pyrometer yet but I know it is at or less than HT temps. I normally only use my big forge now. I have a smller one abut i leave it at the foundry were i give classes. The smaller one uses a little less gas but not enough to worry about. Since I have gone to dry welding I don not have the probelm with flux now. Oh SHHHHHH don't tell my wife I don't need 2 forges:D . I have 4 right now but only use the 1, Keep one for backup. one really big one 14" dia and the smaller one 8" dia.

Ok, I've heard tell of dry welding, but since you say you're doing it it's question time ;)

Are you just doing really good surface prep, or are you using a can, or is there some other cool method?

Really good surface prep, then weld up all the seams with a mig/tig welder. Goes together sweet and you can weld at lower temps. I do use a can for some of my other stuff like cable. I have even weled up the ends and welded plates ti the sides. it works slick, and alot less grinding to get off the weldment.

I don't even want to think about how many forges are in my shop... but I will :)

1 main forge coal fired, used for most of my forging, and non-knife related welding (I'm a blacksmith who makes knives)

2 portable "face" forge, which has a conventional firepot, and a forge surface above the firepot. (coal fired)

3 rivet forge (coal fired) for traveling demos where I'm just going to be doing little stuff.

4 another rivet forge, for loan, or when I need 2 or more forges at 1 demo.

5 the "peach" vertical welding gas forge, I can also ramp it down to forging and heat treating temps, but because of the size of the chamber, not very ecenomical to do so

6 horizontal gas forge used for forging long stock under the power hammer 6" diameter chamber 16" long (usually blocked off at 12")

7 heat treating forge, it's horizontal, but with spaces built in for graphite "risers" (graphite is super heat conductive, and ensures a perfect atmosphere)

I also occasionally build other forges for certain things when I need them.
