As a professional HVAC tech and welder... It’s always been a pet peeve of mine when people interchange the terms brazing and welding and even sometimes calling it “braze welding”. The succinct difference between the 2. Brazing uses a filler rod, a DIFFERENT metal than the parent metal, that melts at a LOWER temp than the parent metal to join parent metal(s), think “gluing”. Welding uses filler rod, a majority of its composition being the SAME as the parent metal, requiring melting BOTH the filler AND parent metals to join parent metal(s). Basically making 2 pieces of metal 1. “Gas” welding is just a class of welding that uses ANY type of flammable gas (hydrocarbon), usually also requiring pure oxygen, to melt the metals using an open flame. BTW, Nice work George...

@@897473 There is no terminology problem. Its actually 3 things or I could say 4: welding, braize welding, brazing and soldering. The one you show is actually braze welding. Brazing requires tight clearances to take advantage of capillary attraction. To call it brazing you would have to buttit tight, preheat the joint and fill it in one or few points and let the brass FLOW....no dipping along the joint necessary. Its common industrial often automated process. For repairs though, like cracked castings you may not always able to use capillary advantage. So you may need to bevel the joint and welding technic to fill it up sometimes in a few passes...

@@andriyshapovalov8886 NO! you are wrong. In technical terms it is very clear that Welding is different from Brazing and also different form Soldering. To recap it all, again Welding is joining for example two Same Parent or Base metals using a filler metal (welding rod) with the same composition as that of the Base or Parent metals being joined together. On the other hand, Brazing is joining for example two Same Parent or Base metals using a Different metal with lower melting point as a Filler metal (brazing rod), and Soldering is the same principle as that of Brazing only that you are using a Different metal with a Much Lower melting point than that of a Brazing rod for example a Lead as a Soldering material. When you say Braze Welding that is absolutely Wrong! What you mean maybe is Braze Joining, or Weld Joining, or Solder Joining of Parent or Base metals. Also to add to this, Spacing or Gaps has nothing to do with the definition or differentiation of the Three processes. I know for sure because I am formally educated with these processes.

Thank you for this video. I actually use soldering and brazing in jewelry making for much smaller scale sculpture and attachments. I appreciate your in depth explanation on the difference in strengths; as well as your appreciation for the artistic value a bronze brazing can add.

Electric welding is either with the Mig, Tig or Arc welders. Today, gas welding is not used much in industry but oxygen acetylene welding is an important tool in the small shop or the home shop. You can both braze and weld using the oxygen acetylene torch.

@Spruce-Bug

Is that because the oxyacetylene torch heats up too much? I guess if you were welding cast iron, the torch would be better than electric welders. keeping the pieces warm and slowing down the cooling process.

+Stephen Bennett Stephen, it could be a number of things. Check you tip and be sure it is clean with no obstruction. Try changing your mixture of oxygen/acetylene. Example: Turn the knob so you get a bit more acetylene or oxygen. May have to increase the pressure at your regulators. May have to hold your torch in a different position so the sparks don't fly up into the torch tip. Maybe holding the torch too close to the work you are welding. Try varying the distance between the blue cone anyou are d the metal you are welding. Make small adjustments. If and adjustment increases the popping, try the opposite. Let me know how it works out.

I absolutely love brazing I always have since I was a little kid in junior high first learning it I loved it and my teacher came up to me and took me aside and he said I have never seen any student is good at breezing as you he said don't tell anyone I told you I will deny it because he didn't want me to**** *** any of the other kids. But that teacher changed my life he made me feel like I could do something and I was good at something I had very low self esteem before that teacher took me aside and after he took me aside I felt like I could do anything that I set my mind out to doing he really made a difference in my life and I'll never forget him

Yes, there definitely is a difference between Arc and brazing. It's often said that someone who can braze well is apt to pick up Tig welding fairly quickly.

Not exactly sure what you are referring to. There is a "gouging" tip that goes on a oxygen acetylene cutting torch for cutting out rivets. I've never used one so i am not a good source of information. "Sound Metal" again, I am not sure what you mean by "sound metal". Sorry, I am not much help for your question.

Great techniqe and advise. Thank you ....I am upscaling from jewellery manufacture repairing my trailer! Kind regards Steve Morrison NZ

So is brazing with the rg45 basically the same as stick welding ?

Can the Henrob torch do everything a Smith torch can? I was thinking of buying a Henrob since that's what I learned on.

I am not sure exactly which video you are referring to. Clean metal will always braze or weld better than rusty, oily or paint covered metal. I do tend to clean up any metal before welding or brazing. It saves time in the long run.

Thank you for sharing this information !

If I am using my spray outfit, I use clear lacquer. If I just want to spray a small piece I will reach for a can of aerosol, either acrylic or enamel. There are all grades of paints and coatings. Generally the more you pay the better they are, although that is not always the case. For more technical information you need to find a forum that deals with the chemistry of coatings (paint).

Thank you for the video, which explains something I really didn't understand. My next question is that if welding is so much stronger than brazing, when would you use brazing as a preferred technique to connect two pieces of metal? Thanks again, KB.

Hola exelente técnica mi pregunta es si lo que se hace con cobre aplica a la plata 🤩

Hey George, great video. Thanks for taking the time to do it. Hope you don't mind a few naïve questions: 1. Does one need that welding torch to braze bronze on steel as in your example or can a normal gas torch be used (Bernzomatic)? 2. In your example, if you brazed both sides, wouldn't it substantially increase the strength? 3. Is it necessary to use bronze on steel? Can same technique/temperature be used with a steel rod on steel?

@897473

There is not enough heat from a propane torch. I do not have a lot of experience with propane. You can anneal copper. Probably not enough heat to melt the brazing rod. Welding steel to steel takes more heat than brazing. You can increase the heat temperature with adding oxygen to propane. I have never used oxygen / propane so I'm not a good source for information. There are some videos you KZread for oxygen / propane brazing. Sorry I can't be more help.

I wish you had a #5 lens on the video camera. Would be much easier to see the flame and puddle

Fantastic!

great vid. can you join steel and copper?

I would think brazing is useful where it is important not to melt the parent steel. I sometimes fabricate shapes by dovetailing smaller pieces into the larger main part. Silver solder or bronze filler gets into the joint by capillary action which makes it look like an original one piece forging.

Yeah, that's about how my brazed joints look. I hate brazing. Going from welding to brazing is like someone jacked up your power on your welder and now you have way too much heat. That was a common practical joke when I was learning welding. When it happened to me I just moved the puddle faster. Thing I couldn't stand about brazing is you have to be way too precise on your temp. I still remember that first time I touched brazing rod to the piece of mild steel I has so carefully preheated and then sploosh, molten brass everywhere. It runs really fast and I could never get my puddle control down.

Am I right in thinking for a total noob who only wants to make small artefacts, and has limited room for a metalwork station a mig welder is the way to go? Your welding looked amazing to me, I won't be looking to do that quality for a while.

Question I have is this... is brazing kinda like when plumbers do piping? They are not heating the copper to insane melting temps but they are using another easier to melt metal to "braze" them together correct?

@897473

Good information, thanks. I've never seen it done to see the differences. I hear differing opinions from the metal supply houses. Can 260 or 360 brass be butt brazed? I'm doing a crafting project that would use .063 sheet. I guess I could slip a thicker plate under the seam if that would help... I'd prefer 260 because it is easier to cold form. Also, how easy can you grind a brazed joint down smooth, or can't you? **apologies if you've addressed this elsewhere

Difficult to say without seeing the weld. Things you might check: 1) changing your speed of movement as you progress through your weld. 2) keeping the same distance between the torch and the metal. 3) Melting more or less gs rod as you move along the weld.

What I mean is, you put the rod ahead of the flame. Vs running the torch ahead of the rod. I've watched several videos and no one explains that part. thank you.

Now I am not sure what you are asking. If I have the torch in my right hand and the rod in my left. Most generally I move from right to left. The torch flame is heating the metal to be brazed or welded and is ready to melt the rod when the metal is up to brazing or welding temperature.

I need to add an extension to a torsion spring arm. I'm thinking that brazing will be a good application since the metal rod of the spring will be possibly annealed but not brittle as a weld might make it. Am I correct or should I consider welding. Either will be using Oxy/Acetylene.

I'm guessing that you do not have enough heat for the rod you are using. You might try using silver solder or SIL-FOS which has some silver content. Both of these will melt at a lower temperature than standard brazing rod. I've never brazed with butane so I just giving my best guess.
