I would like to weld this

[atcig]

I want to weld two of these drawer slides together for an idea I have. I'm wondering if it would be ok if I just grind off the finish where I'm going to weld? It says it is zinc finish.
Also would there be any problems with the ball bearings. Any kind of tips would be great.

Yes remove the zinc plating. If possible disassemble the rails. If you can't disassemble it, keep the bearings moving during the cooling cycle.

Thanks I'll give it a try. If I mess it up I'm only out $16

depending on how good of a weld you need and what process you are using you might not have to remove the coating. Best thing for the ball bearings is disassembly otherwise cover them with grease. Spray everything with pam cooking spray or anti spatter spray i'm guessing your mig welding this.
