Can i braze with propane

It heats faster but it is hard to see when the part is ready. This is how I did the left braze in the picture on the right above. I took three fire bricks bottom, back and top and cut a groove in the top one.

I put the assembly in and poked the torch in. Everything turned red and it was hard to tell when it was all done. I think this oven method took about half the time of the method above. In both case the brazing was fast. However they were small parts and they were both insulated from the surrounding air. The part resting on the fire brick was protected plus the fire brick only turned red over an area with a circumference of about one inch so it did nice job of localizing the heat.

Therefore, acetylene is better for cutting than propane. While temperature wise acetylene is hotter than propane the fact is that people are using propane for cutting incorrectly.

The mistake they make is that they are cutting with propane as they would cut with acetylene. Where the heat is in the propane preheat flame is not where it is with acetylene. In short, it takes a different technique to use propane for cutting and in general, acetylene preheats faster. To say propane gives off less heat it is not correct plain wrong actually. Acetylene is hotter but gives off less heat. This is a fact. The available heat from propane is higher. You need to add flux and I would recommend Black flux.

I think you could use a propane torch if you built a little oven for it. I have a picture showing a set up for band saws using a blow torch.

I think almost anything else would be better. If you go the bottom of the following page you will find more information. This version is quite a few years old but is still very good for the basics.

How about learning to use the URL function provided? The same link could be one word long.

Propoline sp can be used with a small Propane torch head. The tip of the torch will turn cherry red. Penetration only comes after you heat the base metal to it's melting point. The Bronze has a low melting point. The carbide does not! Buy a real torch or get someone else to do it for you. Quit being so cheap! I had no trouble getting the URL to come up from Rusty's post, provided I was careful about not including the parenthesis on either side of it.
