    Default Stick Welding Steel to Cast Iron + Clamp Mini-Project

    Goodmorning everyone!!

    So, this is my latest mini-project:

    Recently, I wished I had a way to tack things to the "inside" of my table... Too far from the edges to conventionally clamp them... And this is what I came up with...

    I bought a BESSEY 8" C clamp from the local lowes, spark tested it to determine it was malleable iron, and then cut if off and simply 7018'd it to a couple scraps of mild steel plate, which I can tack anywhere I need to...

    Anyway, the clamp welded very well... It was my first time welding malleable cast iron, and first time welding dissimilar metals...

    And I got another tool for the shop... I'm pretty happy with how it came out

    Just thought I'd share... I'm probably not the first one to come up with this idea... Hope you guys enjoy the video, and have an awesome weekend everyone

    That clamp should be cast steel and weld just like carbon steel, so not really two different metals...Bob

    Oh you just made a grasshopper /screw dog. They work real good for tacking on one piece of steel to align a butt joint or push an adjoining piece down tight.

    I have used cut off c-clamps for 25+ yrs. It's amazing the things I take for granted.

    The only problem with your welding videos Lance is THERE AREN'T ENOUGH OF THEM! :-)

    You've really made my entrance into welding a lot more interesting and successful.

    Thank you and keep 'em coming!
