Welding to universal radiators

I've heard more than one person claim that chinese "aluminum" ain't so aluminum when it comes to welding.

They're obviously welded together at the tanks. So something must work.

I may just be spreading fake news, but thought it was worth posting anyway.

I moved to a universal aluminum rad after my stock radiators proved inadequate for my car's V8. While I was going this route, I decided to have a bung welded to one of the end tanks above the radiator outlet for my coolant temp sensor. This cost me $20 when I brought it to a "real" welder who TIG welded the bung on.

The radiators themselves are mounted with steel brackets that I fabricated by bending and welding myself and then bolted onto the rad supports. THe bottom ones are u shaped and grab the bottom of the tank and the top ones are more L shaped to hold the rad against the top support. I glued some material from my wife's old yoga pad to offer some cushion on the supports brackets and between the radiator and the frame support so it's not just aluminum vibrating/stressing against steel brackets.

To me, this seemed like a better idea (and within my fabrication skills) than welding an aluminum tab on the radiator.

Update. Attacked the radiator last night. It was a large Griffin universal. He was smart enough to retain the old isolators. We ended up building a lower cradle that would sit in the stock rubber mounts and then the radiator would sit in that. For the upper we welded on two pieces of flat to reach out to the stock bolt locations and would use the stock rubber grommet pieces.

Welding to the radiator wasn't too bad. Was scared about blowing though, but I never came close. Does make a huge difference when you clean it properly though (duh).
