Random frame welding/repair question.
I know nothing about welding beyond a basic idea of how it works. My random thought is, if you were to bring a stick of whatever metal your frame is made of with you on tour, would any random farmer with a stick welder theoretically be able to repair your broken frame? Or are the welders of different materials completely different? Like you can’t weld AL with a steel welder or something? Maybe concerned touring folks could start keeping some backup steel, AL, Ti in their steerer tubes or something.

No, welding is a talent, skill, and even an art form and though you might be fortunate to find someone that could make the repair, most farmers/welders are not accustomed to working with such thin gauge cro moly steel and it would be very easy to do irreparable damage. Tig welding aluminum is an entirely different animal and good luck finding someone with the resources and talent that could weld titanium. I personally never get that lucky but then again, we've all heard the stories that some poor farmer in the middle of Malaysia was able to get a cyclist back on the road. That being said, I once was touring with a friend when his chain stay/bottom bracket cracked on his Bike Friday and fortunately we were near a large metropolitan area and were able to get it repaired, though it was one ugly weld.

I get the question now...

Agree with Robow, you are very unlikely to find a welder that could fix a bike frame by welding it.
But if it is a steel frame or fork, you might find someone that can make a very ugly repair with brazing on some extra steel as a reinforcement over the crack or by fillet brazing. But that would be an emergency repair to get you someplace where you could get another frame or fork. In that case, they would provide the brazing materials, you would not carry anything for the repair.
Where are you planning to go that this would be a concern?

whoever has the equipment and skill to weld properly also has a stick. If they don't have the right stick, chances are they don't have the skills anyway.

And as tourist in MSN stated, my friend's Bike Friday weld was only an emergency repair to finish up the next few days before he replaced the frame, it was not "good as new"
