    Default Mig Welding Wire for high strength steel

    I am running into a problem trying to find some .030 or .024 welding wire for a late model 2017 Honda ridgeline radiator core section that I need to replace. It has a tensile strength of 590 MPa and Honda specs require a welding wire with 86ksi + tensile strength. They (Honda) sections run from 590-780-980-1500mpa and require the proper wire tinsel strength +to match the part for welding. ER70 which is what I have always used for older body welding is not high enough strength. Update-I can find the right one only in .80 mm size converts to .0314" Just found this--.035 Hobart 33lb roll of S307208-033 of which is way too much and I would never use it past this job.
    Honda site https://honda.snapon.com/HondaAcura/...temId=66741366 11lb roll is 413.00
    Called Crown Alloys and they have an .035 wire that is Crown Alloys ER 80S-D2 and can get in 2lb spool.

    What about your 'welding supply dealer' where you get your tanks filled/exchanged who also sell welders and supplies? I would stop by one of those shops. Might either be on the shelf or they can order it for you. Good luck.

    the .0314 wire should run through your torch ok. thats only a bit less than a thou and a half larger than your .030. if it's sticky at the tip use a worn out one, or ream it with a cutting torch cleaner.

    Henry, for some reason they think you are from Mars when you call and ask them for a spec welding wire like this.
    I called Hobart, Crown Alloys and another main line welding equipment manufacturer as well as several on line companies. Only Crown Alloys knew about the Honda specs.

    this wire is used for pressure vessels, has the tensile strength you need. might be a solution for you. i know if has nickel in it, might make it a bit spendy. i haven't priced it out, but esab makes great stuff.

    Honda has 6 different grades of High strength steel (on the same vehicle) that is covered under their weld wire specs.
    270MPa
    440MPa
    590MPa requires wire tensil of 86 ksi or greater
    780MPa requires wire tensil of 113 ksi or greater (this is where the Crown Alloy ER 80S-D2 wire falls) 11.50 for a 2lb spool
    980MPa requires wire tensil of 142 ksi or greater (this is where the Bohler Union X96 falls) = around 400.00 for one 11lb spool
    1500MPa requires mig brazing
    That Bohler Union X96 Is from Honda info I found that covers up to 980MPa for plug welds and 780MPa for spot welds. .8mm = .031” diameter wire

    The Bohler Union X96 would be fine except for cost as I am only making a few welds. Crown Alloy ER 80S-D2 comes in 2lb spools. It's shortcoming is that it doesn't come in .023 thru .030 diameter. Have to work with .035.

    the crown seems like the obvious choice. i don't think you'll have too much trouble with .035, unless it's a tough wire to weld with. i'd do a couple of practice coupons and see how it performs. i bet as we see more of this kind of construction from the auto manufacturers, we'll see more wire options from our suppliers.
    the area you're in can play a huge role as well. when i was working in the kent valley,(home to boeing) we had tons to choose from. now i'm in a more rural area 60 miles south, and we just get the basics...
