one question what the hell is the copper loking stuff on the bead ive been freaking out since i switch back to gas from flux and stick ive been getting those shiny copper looking spots

and also to set a welder i always try to find scrap thats the same thickness and have some one adjust my wire speed while i weld till i get that solid burning sound. you can adjust it yourself but why do that when you just bought pizza and beer for all your friends who are chillin around the garage make em do somethin!

the copper lookin stuff is gas slag...

its kind of funny to read some of the advice on here from people who dont weld on a professional level, i thought i was a good welder until i got a job as a fabricator, and found out i didnt know shit....

which advice are you talking about

This is some excellent stuff.. Who said SSM was nothing but Good thread

The thing that helped me the most was to relax. When I first started I was tensed up and squeezing the gun so hard my hands would start cramping. Once I learned to loosen up and relax my beads started laying down smoother and more consistant.

because my welds are consistent and penetrate well, but they look like one solid bead and not stacked beads like yours above.



your weld is actually stronger then the stacked dimes, because there isnt a hot/cold hot/cold points like the "dimes" (the low spots in between the dimes are teh eak spots of welds, every one has a diff way tho)method as its just one hot burn, smilar to a stick weld.easier to grind also.

if the hot cold hot cold effect was the reason it was weak, tig welding would be weak welding as well......right?

Wrong. With TIG, the heat is always there, never pulled away. The gun provides the heat, and you provide the wire. With MIG the wire is what provides the heat. So every time you let off, the metal has time to cool down. Stitch welding really should be used on anything that will see a lot of stress.

This was the prep (good prep is always good)

Then welding

Then some stich welding on a brake switch mount.

anyone got any pics of good solid structural mig welds not stiched. If its not really a dime effect what should it look like. My welds look like shit cause im just practicing but i dont really even know what a good weld should look like

It can still look like a dime to an extent. But technically laying down a stack of dimes with a MIG isn't the proper way to do it if you go by textbook.



This is, more or less, a textbook weld.

here are a few more.. this has anti splatter liquid sprayed on it, hence why it looks weird. its shit they make us use at my old job.



here is a gusset on an engine cradle.
