MIG Welds

I have been trying to teach myself to MIG weld. It seems to me that they are a little cold. Are my assumptions correct? Do I need to go hotter and increase my travel speed to not burn through?

Turn it up just a hair and try a little more of a circular pattern than a back and forth. It might give you the look you want.

Thanks. That seems to be working much better. I appreciate your help.Poland308 wrote:Turn it up just a hair and try a little more of a circular pattern than a back and forth. It might give you the look you want.

MIG welding can take on different appearances depending on different technique, fit up, position. You just kind of learn through osmosis over time as you weld to adjust.
- I don't really like doing rails with MIG prefer TIG but these are just down and dirty industrial. See how the weld appears to be humped up around the pickets?

- Same exact machine, same settings on a cope joint, different looking profile entirely.

I'll keep that in mind. I didn't know that. I have watched Jodi's video's on you tube and his MIG welds seem to lay flat while mine seemed to have more of a crown and the edges (toe) of the weld didn't seem to cut into the metal. Thanks you for your response and pictures. That really helps.DLewis0289 wrote:MIG welding can take on different appearances depending on different technique, fit up, position.

You are not melting the metal.
Imagine this. Tjoint , starte puddle, hold there till it builds puddle, move to right or left(center) then to top, pause for count of 1, back down then repeat.
You are melting one metal, pooling it, bringing it to the other metal to fuse them together. I hope this helps. Till I knew this, it was a lot harder.
Metal doesn't always melt soon as you touch it. Unless its stick.
Makes sure you are melting metal and pulling it to fuse with other metal.
