Re: Chrome plated mild steel - How to Approach Welding a Crack

Again, thank you CJ for the direction on this. Just to follow up.... This is the result of my lame attempt at welding this crack in chrome plated mild steel. As suggested, cut a slit in the crack & ground back as much chrome as I could.... but never could get it all. Nasty stuff when the chrome ...

cj.... yeah, I think you're on the right / same page. That support arm carries the rear muffler (in the RED area (R)) and a portion of the front muffler (in the BLUE area (F)). The 2 standoffs are where the support arm bolts to the frame. 52 years of vibration has taken it's toll on the support arm....

Re: Chrome plated mild steel - How to Approach Welding a Crack

Thx for the direction cj.... ok, I'll grind the chrome back & just do it. The crack is all the way thru (not a surface blemish), and is right next to one standoff. Drilling probably not an option. Should work fine if I just do it, I think. You sure it’s chrome-plated mild steel? pretty sure. It ...

Just to close my question off. It's not pretty, ugly actually, but I got it done. I struggled closing the wide gap..... tried a few things, adding packing, added filler rod. In pretty much every case the packing or rod would melt first and not meld into the base material. Eventually, after multiple ...
