Welding to 14b housing

[85mudblazin]

yes I have done alot of research on here and pirate, but has anyone actually have a weld fail due to welding mild steel to the housing?? I have always heard to pre-heat and use nickle rod but I have also heard of lots of people just pre-heating and using flux core in a mig. I have also "heard" of the cast breaking off around the weld because it made it brittle.
I need to weld some tabs to my 14b housing to run a limiting strap, all I really have access to is a mig. Real world experience??

I have welded to my 14bff housing with a mig welder with flux core wire. It is for my limiting strap setup and has lasted ok sofar. I just made sure I had alot of weld surface.

The 14FF is cast steel, you can weld it with pre-heating and mig, or flux/stick welding. The D44 however is cast iron and will crack quickly even with pre-heating.

why would the front end be made from iron and the rear from steel?

dont mean to hyjack but, that seems kinda weird

prolly has to do with Dana using cast and Corporate using steel

On the 14b, do you need to pre-heat when welding to the tubes, or just the center section? I just need to relocate shock mounts.

A year ago...
I had to re-plug weld my tubes in my 14bff.
Rene coached me.

I just preheated the housing...and MIGed the plugs.
The welding went quick...this cast melts easy.

I forget the type of cast iron Rene called it...
but there is no doubt...it's cast iron...not cast steel.
