Bake Hard Question

Bake Hard Question

Bake Hard Question

(OP)
I have a dumb question. Can Bake Hard Electro-Galvanized be welded?

RE: Bake Hard Question

I'm certain it can because this material is designed for automotive bodies that are normally spot welded. The bake hardening effect comes from excess Phos. During the paint bake the steel actually age hardens slightly. (I forget what SAE J#### to look at but the specs are in there.)

RE: Bake Hard Question

Yes, eletrogalvanized bake hardening steels can be welded.  The appropriate standards are SAE J1562 Selection of Zinc and Zinc-Alloy (Hot-Dipped and  Electrodeposited Coated Steel Sheet and SAE J2340 Categorization and Properties of Dent Resistant, High  Strength, and Ultra High Strength Automotive Sheet Steel.
