A number of years ago (35). I took quite a few welding classes through high school and college. I wasn’t an expert but became pretty efficient with an arc welder (I believe they are called stick welders these days) and oxy acetylene torch. You don’t know how many things I welded with a metal coat hanger. This was before the small mig welders came available, so I never learned the proper techniques. Anyway I don’t have either an oxy acetylene torch or an arc welder. But I do have a small mig welder that I bought in 2006. To date I have only used it a few times to scab things together.
As I am starting to repair and weld my motorcycle frame, I am finding my skills are a little rusty. I tried looking for a local vo-tech that offers adult or hobby welding classes but am coming up short. My biggest thing is learning the basic setup for my mug welder. I did find a hobby welding school in the Chicago area that offers an all access video subscription on mig, Tigue and stick welding basics. It is about $30 a month. I think I will check it out.
Here’s my welder and project.
I drilled a through hole to weld in a splint through the frame crack.

Nothing like jumping back in the saddle with a low risk project! :lol:

I would buy some scrap of similar material and thickness to practice with. Maybe cut it apart to see if you're getting good penetration?

Looks like your wirespeed may be just a tiny bit high, but that makes better sense if your going to grind them.
Wonder if tubing on either side of the welds will be more brittle too?
Any way to make a gusset that ties this area together for more strength over a longer area of tubing?
Maybe use some salvage steel from a Mopar anything?
Nice work!

As your discovering welding around a small diameter circle is difficult with that welding process. Material stacks up fast. That machine with solid wire snd a shielding gas is designed to run within the parameters of what is called short circuit or short arc transfer. Meaning the arc actually extiguishes and restarts at I don't remember what frequency, but that is why sound is so valuable when it comes to machine setting thats what creates the sizzle sound that most people look for.
It does not change the fact that when the setting is on it is going to be difficult to weld around a sub 1 inch pipe.

Alot of wire processes and stick and especially short arc have the characteristic of cold starts.
Metal piles up but does not penetrate the base material.
To compensate for this when welding a crack, start before the crack and weld into it. In cases where there is no runway you may be able to use a piece of scrap and tack on a run on plate then cut it off when done.
Creating a V groove is benificial when welding cracks. Wire sizing can also play a factor.
For work like that I would prefer .025" to minimize pile up.

Anyhow, I could carry on forever like a keyboard
Professor but it's largely about time spent. Access to in person tutoring will probably give you a 5x return on time spent.

As an aside that frame looks to have some design failure issues. I may be common for them to fail in that manner. Which means it will likely fail again, especially after a repair. So if you are going to ride it much you need to alter the design.
Most likely through gusseting. It looks like the factory had gussets in there.

If you move your gusset to the top of the tube rather than in the throat of the joint, it will be more effective. Often with this method you can do both sides and assure that the next time it breaks it will be somewhere else.

Thanks for w feedback. I am getting better and have watched and listened to a few tutorials. You are correct sound of the welding makes a difference. Adding the gas also made a world of difference. I am getting good penetration as I have had to fill in a few holes with good success.

As far as structural, I believe there were some design flaws in the structure. If you go to towards the top of this thread you will see where I drilled through the connecting structures and added a support rod. It is secured where it enters and exits the frame as well as to the bottom of the frame. Also on the kickstand side I am needing to add a bottom gusset plate as well. When I get done it should be better than factory. I don’t plan on freestyleing or moto-cross when I am done.

There are a lot of schools where you can increase your welding skills. And I recommend you do it because for a man these skills are really important.
