What type of welding is used for small jobs?

MIG welding is probably the easiest to learn. Is there a community college nearby? Check to see if they have any classes.

@raum – Have you used a plasma cutter?

I haven’t done any arc welding myself. Have only watched the instructors do it.

I worked with kids. Mostly stuck with MIG. The more advanced kids did some TIG.

After you graduated from the welding class, you could take this class to make your own bike frame. It was pretty cool what the kids came up with.

@raum- Is TIG used for bigger jobs like cars & ships?
What kind of metal were the bikes made of?

Both MIG and TIG seemed pretty heavy duty.

Not sure. Steel or aluminum?

If you’re looking for something lightweight, could you just solder it?

Brazing, soldering, gas welding with a acetylene torch would do the job for many thin, light materials/metals.

@raum I don’t know.

You can solder copper or cold roll pretty easily. Maybe not aluminum though.

Brazing and gas welding are also options. But they require higher temps. I would do those in a proper shop.

Just sent this question to @LuckyGuy

@raum -Thank you :)
