How to MIG Weld : How to Prepare a Butt Joint for a MIG Welder


Hi I’m Mike Rogers and we are making this
video for expertvillage.com on the uses of a mig welder. This stage is how to join two
pieces of steel in a butt joint. So we have two pieces all we are going to create is a
longer piece of steel so this could be to create a area or to repair a section of a
vehicle or a chest or something we need to join this together. If we just lay them like
that and weld we wouldn’t get a very good not a very strong join on the steel. So we
are going to V this with the angle grinder before we try to weld them together. Lets
show you. First you clamp the steel down before you use the welder. You would use a simple
friction clamp for this job. Then we use our angle grinder. Don’t forget the safety. Already.
I’m doing this to both piece of steel we are going to create a V section to the half of
thickness to the battle. Okay as you could see now when we weld this together we are
going to have that nice V …to feed the weld into.

  1. Completely wrong angle of the Vee. The Vee should have about 50°, and not the maybe 120° he's been grinding.

  2. lol, your not supposed to angle it! thats pretty much cheating, id like to see you weld a butt joint on 1/4 plate with out angleing it
