Welding steel tubes to chrome-moly
Welding steel tubes to chrome-moly
(OP)
I have a situation whereby I want to weld structural steel tubes to an existing chrome-moly pulverizer wheel (used at power plants to crush coal). These wheels are not required by the power plant anymore because the local power plant switched from coal to natural gas. I want to weld the ends of small tubes (2 1/2" square ASTM A500 Grade B Carbon Steel) to the chrome-moly wheel perimeter. The wheels will be laid flat. The tubes are only 1' long and will cantilever out from the chrome-moly outer perimeter and will be used to support a decorative perforated steel seat. The wheels are about 4' in diameter to the outside face and look like steel wheels (doughnut shaped).
Can it be done? If so, what kind of welding process is required? Electrodes? Preheating requirements and any post welding techniques?
Any help would be appreciated.

The only other piece of information I have about these wheels is the term "gasite 20". Does that help?

The tubes are intended to be welded to the outer rim of the wheel and will be part of a bench seat support structure. The tubes will be equally spaced at 30 degrees on center around the outer perimeter in a radial fashion. The tubes will support a live load of 100 psf or a point load of 300 lbs whichever is greater at each tube. The welding of the tube to the wheel is intended to create a suitable welded connection capable of resisting shear and moment.
From what you tell me, this idea seems improbable.

I would look into welding plates onto the tubes and creating some sort of bolted connection rather than welded.
