Welding aluminized to stainless - possible?

Welding aluminized to stainless - possible?

(OP)
Is it possible to weld aluminized HR steel to 409 SS?  My limited resources say not.  What say y'all?

RE: Welding aluminized to stainless - possible?

No. You would need to locally strip the layer of aluminum or aluminum-silicon coating from the HR steel surface, prior to welding. The 409 SS is weldable to the carbon steel parent metal.

RE: Welding aluminized to stainless - possible?

The brittle intermetallic compounds of Fe and Al are the problem. If your welding is by friction, laser or some other method which precludes the diffusion-driven formation of these compounds, you can achieve a weld. Cast stainless ring carriers are bonded to aluminum pistons. The bond is good when the process is well executed.
 
Under any normal welding conditions, expect a very weak weld because of oxide and intermetallic compound layers.
