— Soldering and Brazing processes differ from welding in the sense that there is no direct melting of the base metal (s) being joined.
— Rather, the brazing or soldering filler alloy flows between the two closely adjacent surfaces of the workpieces by capillary action.
— Both soldering and brazing processes are particularly useful for joining two dissimilar metals.
— Both, the brazing alloy or the solder have lower melting points than the metals to be joined.
— In order to obtain a satisfactory brazed or soldered joint, it is necessary for the filler alloy to
(i) wet the base metal,
(ii) spread and make contact with the joint opening,
(iii) be drawn into the joint by capillary action
— Brazing and soldering processes differ in the following way:
(i) Filler metal used in soldering has a melting point below 800°F (427°C) whereas that in brazing has a melting point above 800°F (427°C).
(ii) The extent of diffusion. In brazing process, bonding conditions are set up so that a large amount of diffusion will take place in order to strengthen and improve the bond, whereas in soldering, diffusion is secondary in importance.
(iii) Brazing produces joints stronger than those made by soldering and they can be used in service at higher temperatures.
I build plastic 1/87th scale models in polystyrene and would like to switch over to metal. Since the pieces are so small I really can’t weld them effectively. What metals can I solder using a 150 watt soldering gun or I do have a brazing torch though I haven’t had luck brazing brass tubes together. Just need to know what light metals I can bond together with soldering/brazing that I can purchase at a hobby craft store and if there are any tips since I’ve only soldered wires together and can’t get anything else to bond. Thanks!

I’m attaching a very very thin aluminum board ( a computer motherboard tray) to a strong aluminum motorcycle frame.
i need the bond to be VERY VERY strong.
i have the current option:
Soldering (using tin or lead as flux)
Brazing (never done this before, please explain)
Braze Welding ( aparently its like brazing but using bronze.. needs to be heated to 800 degrees celcius)
Welding (which type of welding should i use)
From my research on wikipedia… aluminum melts at 660 celcius…
?
I’m not sure but i THINK this might put braze welding out of the equation… Anyways, how should i attach these together. should i get professional help, or just rent some equiptment and try to do it on my own
What’s The Strongest Way To Attach Aluminum To Steel?
My buddy needs to attach a 3″ bronze ball valve to 3″ copper pipe. He’s soldered it twice already and it still leaks a tiny bit and he does’nt know if he should try and braze it. He’s not to good at doing either on such large pipes. Come to think of it I don’t know that he has ever brazed anything before. Open for suggestions
I am new to silver brazing. I have done copper based brazing with acetylene. The silver braze is for smaller parts. Have read Tubal Cain’s “Soldering and Brazing” but his view of equipment is very British. Parafin lamp? Blow lamp? What are good Stateside solutions?

What’s The Strongest Way To Attach Aluminum To Steel?
It seems like there must be some source of energy for capillary action to occur. I mean, water can’t just travel against gravity without any energy aiding it’s migration. This doesn’t make sense to me. I know some people say that it is a property of water and therefore requires no energy, but if that is the case then capillary action could turn to perpetual motion under proper circumstances.
What’s The Strongest Way To Attach Aluminum To Steel?
I’d like to solder aluminum to copper. I already have silver solder paste, will this work?
I have two ends of a metal coathanger and I’m trying to solder them together.
I have soldering wire and a gun, but whenever I melt the solder wire down and try to get it to stick to the hanger….IT DOESN’T!
This is getting so frustrating, and I’m running out of solder spring.
Any thoughts?
Thank you,
John
Why won’t water travel up a larger straw?
I understand what capillary action is I just don’t know how to explain why it won’t work with a larger straw.
Okay, why won’t it travel up AS FAR with a thicker straw.
I am new to soldering. And I need to join a rectangular shape securely. I plan to wire wrap the shape with 24 gauge gold colored wire and also have 5 to six beads arranged in the middle of the rectangular shape which is going to be a pendant.
Can you please tell me the best way to join the 18 gauge wire, I need to know what supplies I need as far as the best solder and solder flux as well as should I use a pencil torch or a pencil tip soldering iron. I have both.
Thanks best answer 10 points!
How do I fix leaking cold water copper pipe without soldering it? Right now the rate of leaking is just dripping every minute
Hello people. I want to buy a pack of good quality and cheap soldering torches for my small business needs. Where can I buy them in Sioux Falls?

They say you’re supposed to use a soldering gun but I don’t have one. If I can use the iron, how do I make the repair?
I am trying to butt solder or braze 308L stainless steel wire with a jewelers torch but do not Know what the best brazing rod to use. I would like to keep the wire looking the same throughout. Thanks for the help.
When soldering valves onto copper pipes with MAPP gas, how does the heat not damage the internals of the valves? Some have rubber washers (like the small shutoff valves under the sink), and the ball valves that go onto pipes (like the one for the water heater) has nylon parts in it to seal against leakage. Someone at Home Depot said that valves are easy to damage while soldering, but I’ve soldered a few dozen of them and never had any trouble.

I don’t know how to braze weld or solder so what I’d like to know is would I be able to use JB weld in place of soldering or brazing? Will it last? If people can repair a radiator with it can people do some plumbing with it?

My my wife ran over a garden tool and it put a small hole in the AC line that connects down by the bottom of the radiator. I have found the hole and was wondering if it can be soldered or some kind of weld can be done to plug the hole. I hope this is not an expensive repair.
Thanks for your response.

I did an experiment where I found the capillary action of several liquids. Basically, I put the capillary tube in a liquid and then measured how high the liquid travelled up the tube. How do the intermolecular forces of a liquid affect how high up the tube the liquid goes?
Does this mean there is a strong positive relationship between adhesion and intermolecular forces? When the intermolecular forces are stronger, the adhesion of that liquid is also stronger?

I have tried soldering i have tried brazing and i have tried welding they all don’t work. I have to keep the aluminum track channel open and the two ends i am trying to connect have to be strong they are under a lot of stress any ideas?
Hey guys! Tell me please where to buy nice quality soldering kits using internet? I don’t nave much time, so I’ll be grateful for quick answer.
