Is it realistically possible to braze steel using a standard propane torch?
Have any of you brazed something like a bicycle or a bicycle trailer, that has to take a conciderable amount of abuse, using just a propane torch and the standard tip?
I have gotten metal red hot using just a propane torch and a standard tip (a tip that might be used to solder copper pipes together) , Whether that was hot enough to braze with is the question.
If propane is hot enough to braze with are there any tips you may have to reduce the amount of propane used and to strenghten the brazed area.

No, Propane does not get hot enough. In order to braze metals with any considerable amount of strength,You need a gas mixture that creates enough heat to allow the metals to reach what is called the eutectic point. (Just below the melting point of the base metal) Propane torches are basically made for soldering copper pipes. It should not be used to join metals that require any amount of strength. I suggest you get a mapp gass torch kit. Or an arc welder.

There are Youtube videos of persons shown brazing steel parts with bronze rod, using propane & oxygen, so yes, under those circumstances it does get hot enough. A torch that mixes the two gases is necessary. I'm curious if a person can use propane and ordinary air, as in from a compressor.

From my experience, if you want to braze, you need an acetylene torch. Propane just doesn't burn that hot.

What is this? a trick question?
The word "Braze" refers to non-ferrous metals.
Steel is mostly iron.
Anyway, you can't "braze" anything with a propane torch; the temp is too low.

Yes, I have done it with small parts, but it required the parts to be in a charcoal fire to preheat them. Realistically no.
