    Default mild steel to stainless

    When welding stainless steel to mild steel is 308 rod better or wirefeed better. You should use stainless rod over steel rod to right?
    Thanks for any help

    Either or will work but you always want to mach the filler material to the higher grade material, in your case the stainless

    I would use 312 or 309.

    Default mild steel to stainless

    Ya 309L is designed for "dissimilar metals". Or carbon to stainless

    cabininthewoods,

    Here are a few samples I made in response to your question.
    I had been wanting to try different alloys for a while so your question was timely.

    Base plate is 1/4" 316 ss.
    Carbon steel square tubing is 1" x 1" x 1/8" wall.

    Tig parameters:
    3/32" 2% thoriated tungsten - ground for each alloy
    90 - 100 amps DC - HF start - no pulsing.
    Argon: 15 cu ft/hr flow - .5 sec pre flow - 10 sec post flow.

    Wanted to minimize variations for the test but some factors are:
    1 - Wire diameter for alloys varied from .035" to 1/16" as this is what I had on hand.
    2 - Most troublesome one - the bozo (me) behind the mask.

    Alloys;
    C22 = hastelloy C22
    INC92 = Incoloy 92
    RN67 = 30% ni - 70% cu

    Observations:
    1 - The RN67 alloy puddle was dirty and sluggish so it may not have been a good choice.

    2 - The 308L, 309L and 312 alloys seemed to "wet" the pieces the best compared to the others.

    I realize that the alloys I used may not be suitable for this application and, as I have no way to test these samples for strength, please consider this as a simple weld bead appearance test.

    Perhaps a more knowledgeable member can shed some light on these results.

    Other samples will follow in next post.

    too much time on my hands............................................. ......
