Before starting you might consider reinforcing the cracked tubing 
with a sleeve that encircles the crack area, or a piece of bar stock 
(maybe even bare carbon steel bolt material).  Practice on some other 
steel parts, perhaps other bare carbon steel bolt material, etc.)

Welding supply stores will sell a couple of brass brazing rods and 
flux.  From there, remove loose scale and dirt from adjoining parts, 
heat end of rod for a few seconds, heat area evenly using a slight 
circular motion until the metal appears cherry red color (of course 
you'll be wearing goggles that will turn everything green),  dip hot 
end in flux, rest the dipped rod on the joint then watch the braze 
alloy flow through the joint. Repeat heating the rod and dipping in 
flux as the rod is consumed into the joint, and continue the process 
until the joint is filled by the brazing material.

I hope this helps.  Books describe this in a few short pages.
