  • Welding chrome plated steel questions

    New to the forum, tried to find the answers I was looking for but no luck. I've only been in the field about 2 years, and have never welded or witnessed anybody welding chrome plated steel. I'm aware that chrome is poisonous when in gas form, and not to weld it, but people weld it when they grind it down to bare steel. So my question is, how far from the welds should I grind? I'm just doing a small side job, cut open a muffle for a buddy's mustang and gutting out the baffling so it's loud as can be (don't know why he wants that so don't ask). I'd like to keep this as cheap as possible and avoid replating. Only the tip matters appearance wise. And I'm also wondering if a simple dust mask will be ok for me to wear while I'm grinding it off. Whole thing is kinda a quick hack job I've been doing at lunch, and he's ok with that.

    Hate to do this, but I still need answers. So bump! I just wanna know do I only grind off chrome where I'm welding or do I go like 2 inches or so from where the bead will be? Then what? Clean with acetone?

      Depend if you tig it or mig it, 1/4 it should be enough when comes to chrome grind off, but it might continue peeling off because of heat.

        I'd prefer to mig it, just because I used a cutting wheel to cut the thing open and it's a little rough, so mig would be a little easier, but I have no problem tig welding it, I'm fortunate enough to have a job where I have access to whatever I need. Any recommendations for which process to use and why? Much appreciated!

            That doesn't looks like chrome plated muffler, that seems like stainless steel muffler...
            To be honest I don't know if they even make chrome plated mufflers for the cars...
            You can mig it with stainless steel wire.

              I agree, looks like the typical low-grade stainless most automakers are using now, just to meet the legal warranty requirements for exhaust systems today.

              In any case, very few (or none) metallic materials create "instant death" when welding or cutting. It is continuous or long-term exposure that creates problems. If it was "instant death" you'd probably be dead already from cutting it open. Grow a set.
              Obviously, I'm just a hack-artist, you shouldn't be listening to anything I say .....

                the "grow a set" comment is much appreciated.... Like I said, I'm new to this type of work, anything we do at work is all new, and nothing automotive, if anything was to be chrome plated it would be plated after we work on it. And no it is not stainless. If it's not chrome plated, it is definitely still some kind of plating that I assume caution would be best with. All the answers so far are much appreciated. I think I have the information I need, but more knowledge is always welcome, thanks guys.

                  I'm not necessarily right about saying it's plated, but my understanding is that only a few grades of stainless are MILDLY magnetic, and mildly only, I was able to pick it up with a magnet that isn't that strong. So I could be wrong, I suppose if it were ultra cheap stainless it's a possibility it would be more magnetic. So any insight is much appreciated. Haven't tried welding it yet but I guess that will settle things LOL

                    Magnetic doesn't make it cheap. It simply means its a different grade.

                      400 series stainless is very magnetic.

                        It's good to go on google and do very simple research about SS and different grades before jumping on forums, people they know very little about metallurgy and metals make statements that SS is not magnetic.

                          Like I said in my earlier comment, it was my understanding that certain grades of stainless were magnetic, but only mildly. I do my best to do research, and try not to bother people on a forum unless I know I can't find what I'm looking for. But I wasn't on here to ask questions about stainless steel, obviously I'm less experienced than most people on here, but if it bothers you that much, just remember I didn't ask anybody specifically to waste their day away on a computer answering my questions, you chose to come on here and comment. Fusion king - I understand cheaper doesn't necessarily mean more magnetic, I just assumed cheaper meant closer to mild steel, which in my head means more magnetic. Thanks everyone for all your input, glad to be learning.

                            It may be aluminized steel. That is a very common material used on newer cars exhaust systems. This can be migged with no removal of the coating.
