Brazing Steel with a Propane Torch - Repairing a Mounting Bracket 

謝謝！

Higher power propane torches definitely have the heat needed.

How big is the piece?

I actually did this exact thing, ended up letting the gas out of the cylinder and warping the base

As a budget welder to get started, yes. However I found it could not handle 3/32 7018 electrodes despite claiming to so I returned it and bought a Forney 120v stick welder for $200 which works great with 7018.

We’re you using AC 7018 electrodes? But thank you, I’ll have to look into the forney 120v!

@@yakov5604 Nope, just regular 7018

Ive been a welder for 18yrs my dad was a welder now he is a nuclear welding engineer and my grandfather taught him how to weld. I will say without a doubt that Amico makes the best budget welding machines. The cts has plasma cutter, stick welder, and tig (I know every stick machine can tig). The mts is mig, tig, stick. Both will run off of 110 or 220. Check em out. Chicago electric will always be trash. They're small spot welders that's all.

​@@rebel1187What do you think of the cts-200, or would the cts-400 be the better choice? I want to do light stuff up to at least 5/16. Currently using a 220VAC flux wire Lincoln and a 50's 220VAC buzz box for stick. I want to add plasma cutting.

You'd need bronze brazing rods

Can you let me know which one to buy cause there so many thank you

@@ivettemartinez2212 Bernzomatic sells a small package with four bronze brazing rods which would be perfect for small projects.

Ok thanks and it will work with just a mapp gas gas? Or a propane?

How big are the metal pieces?

You can definitely use a propane touch for metal art, but you'll need the right brazing or soldering filler.

@@DragonBuilds I'm gona try it. Initially what i was using was soldering/flux. But what's happening is my finished solders are falling apart if I put another solder near it. I want to combine junk metal together. Kinda like this: www.pinterest.com/pin/441352832211658870/ I will try this technique. Next I may try oxygen acetylene. I'm just so scared of getting hurt.

@@dec23 That rabbit is super cute! If you are making many joints very close to each other I think you will need to use an arc welder. The Forney Easy Weld stick welder I have can weld thick and thin metals, and on lower settings can be used on a 15a household circuit. Welding looks scary, but if you follow the safety instructions and wear good quality protective equipment, you will be fine.

@@DragonBuilds It's very cute. I wana make art with that consistency. Joints close together using scrap metal; bolts, washers, copper, brass, etc. Is this the welder you have? www.forneyind.com/products/welding/stick/welders/forney-easy-weld-100-st-stick-machine The price is decent. My dad says the same about welding. He is an electrician and tells me as long as it's grounded it is safe to use. :) Thanks for your help.

@@dec23 Yeah that is the welder I have. It is a good value. You will also need some accessories like a welding table (Harbor Freight has a nice inexpensive folding one) and safety gear.

For steel of that size you'd need an oxy-fuel torch to braze. One option you can do is to find a piece of square tube that fits inside the rotten post and just bolt it together.

Brazed joints can be stronger than the steel itself in some cases.

@@DragonBuilds no I mean the heating process, I'm thinking about repairing some coping on a skate ramp and brazing seems the easiest way of going about it. However I'm worried it might damage either the coping itself or the concrete around it

@@drumboarder1 for larger projects like a skate ramp you'll need an oxygen acetylene torch or arc welder. Brazing can be done with a propane or MAPP torch for small parts only.

@@DragonBuilds well I'm only talking about a very small section of a 50mm pipe that doesn't meet up with the pipe next to it perfectly and it's maybe 1.5mm thick at most. Outside of weakening the metal or damaging the concrete, filler material would be my next concern, though I haven't looked at it in person for a few weeks so it might not be an issue. Thanks for the replies though and off topic, christ I hope you become the more popular gum flavoured rice EDIT: yes gum flavoured rice, screw it

@@drumboarder1 How big is the gap? Brazing only works on tightly fit joints.
