It is rediculous how much better the copper between the contact and surface trick improves things. I put a copper scouring pad under my clamp and mig welding in general has a super smooth feel now, but when I'm welding stainless sheet metal I'm not getting the annoying wire popping when tacking seams that throws spatter and what spatter I get when welding stainless usually comes off easy instead of needing a smack with a chisel and hammer. The reduction in clean up alone has made things look better and sped things up, thank you so much for that tip

Never used it in a mig. I saw it on a garage door installation. The gold beads connecting the brackets to the track was hard for a welder to miss. Many years ago we used Everdoer silicon bronze rod to connect light gage galv, as thin as 22 ga., duct pipe in granaries for dust collection. Installed in place, out of position with cabon arc pencils in a stick welding leed. Good times.

Paul, I know this took some research and advance scripting, but I think it was worth your trouble. A good and informative episode, and interesting to watch. I like the explanation of brazing as similar to a glue joint, and I think that's exactly right: Something that sticks to the two surfaces and hardens. Doesn't have to melt the two base materials and so they don't have to be compatible. As for zinc, I think I'll continue to just grind the stuff off of the weld area first. I don't have confidence in my skill at keeping the temperatures down, and really want to stay away from those fumes!

@ypaulbrown 2 года назад

BenZ, zinc fumes have a worse reputation than they deserve in my 20 plus years of welding experience, I have never been bothered by welding on zinc, other than the nasty welds it tends to produce, I am sure if you are in a poorly ventilated area, keeping your head in the plumes, you will suffer from Metal Fume Fever......I am not condoning not wearing breathing protection, we just did not use for this episode, due to the limited galvanized welding we did. this episode was about Silicon Bronze and not about welding on zinc coated material......

This video was good to see. I've done just a little TIG brazing (Everlast 210EXT), and the more I do with Silicon Bronze, the more I like it. But using it with MIG really gets me thinking, especially if I would ever want to use it with a low-priced 120V MIG unit (i.e., 220V not really required for that lower amperage), like that new Everlast Cyclone 140E, since I already keep a couple of large argon tanks on hand.

Great video. I didn’t know this type of welding/ brazing existed, even though I think I’ve seen some of this welding on material over the years but didn’t know what it was. I’m going to get into using this because as you pointed out with thin metal it doesn’t warp. All I have to do is get some argon gas and some wire. I’ve always struggled with thin metal warpage over the years and for a lot of projects at home this would be the preferred process to use. This is a real game changer for me. If anyone is wondering why I’ve not heard of this I’m a retired heavy duty diesel mechanic and I’m used to welding 1 inch plate steel 🤪🤪🤪🤪👍

I’m retired but at home I do a lot of projects that use thin metal and have always struggled with metal warp age because of heat.that video opened up all new avenues for me. That brazing technique/ welding would produce welds plenty strong enough for what I need. I was looking into the cost of the wire and I figured it would be spindly and it is. I’m going to buy a 10lb spool and the cost is around 225.00 or so. But if I’m plan on using a lot of it , in the long run it’s cheaper. Also I need to get a couple of 150ci-tanks if argon gas, I have some tanks already that I can trade out. I need the argon because I also have a tig welder that I haven’t used yet. So I figure my initial buy in cost to get rolling is around 500.00 dollars. So thanks again for the video👍👍

The white smoke is not the zinc "boiling off", it is the zinc being oxidized to zinc oxide. It is an extremely fine powder and if inhaled can damage the lungs. It is also white in color. The white powder is seen on the back side as it became hot enough to be oxidized. I have done a lot of silicon bronze brazing using an oxy acetylene or a MAPP torch depending on the size of the parts. I wasn't aware that a silicon bronze MIG wire was available. Knowing that thin parts can be brazed without significant distortion will open up a number of opportunities for me.

@ypaulbrown 5 месяцев назад

Paul, in an argon environment ,there should be no oxygen to oxidize the zinc, the boiling temp of zinc is 1,665 f, the arc is over 8,000 f....the zinc is boiling off....I am not a chemist, and I may be wrong, so feel free to correct me if you can find some data,,,,,thanks so much for watching and commenting,I have been behind in answering comments, best regards, Paulie Brown....hope you can use to your advantage.....

@GeorgieBoyDaKilla 2 года назад

Average mild steel on a car. How strong would the silicone bronze brazing be compared to a standard weld? Would you be able to cut and replace a wheel arch?

@ypaulbrown 2 года назад

Average mild steel has not been used in many years on cars or trucks, it is HSLA, high strength low alloy.....the problem with doing a fusion weld is the amount of heat put into the base metal degrading the strength of the HSLA. that is why most manufacturers require silicon bronze repairs. the manufacturers use resistance welds for many of their welds, which put very little heat into the material, but repair shops do not have the equipment needed to do the same thing. The worst thing you can do with body repair is use an Oxy/fuel weld or braze as the amount of heat is immense, that was the old way back in the 1920's to the 1960's.....GMAW [mig/mag] replaced oxy/fuel.....everything has changed these days, hope this helps, as far as strength, I will have to assume it is as strong as the original factory welds, When I worked for Volvo Trucks North America [1990- 2002] I learned about adhesive fastening research done by GM, Volvo was their partner back then, that showed adhesive fastening was stronger than welding....and the FAA allows it for aircraft repair and building.......not some type of glue you can get at the hardware store, but it is available from auto body supply outlets......hope this helps, Paul

@SamJ6131 2 года назад

Could you explain to me differences between uses for Aluminum Bronze and Silicon Bronze. When would you choose which?

@ypaulbrown 2 года назад

good question, Aluminum Bronze is stronger, this is from the ESAB handbook, 3. DEOXIDIZED COPPER(a) Unlike electrolytic copper, this grade does not contain enough oxygen to cause oxide embrittlement orporosity if reasonable care is exercised during welding operations. Also, little change in electrical resistanceoccurs across the joint. Deoxidized copper is the type most widely used for fabrication by welding. The tensile strength of a good, sound weld is about 30,000 psi.(b) Welding Technique: Workpieces thicker than 1/4 inch should be preheated to approximately 300-500degrees F. prior to welding. A forehand welding technique will produce the best results. Flux is required forthick sections, and must be applied to both the area being welded and the rod.(c) Welding Conditions - See Chart on Page 14.4. COPPER-SILICON ALLOYS (”EVERDUR”, ”HERCULOY”, ETC.)(a) General: Excellent welds are made in these alloys without requiring flux. Plates up to 1/4 inch thick aregenerally prepared with a square edge. Forehand welding technique with DCSP is generally recommendedfor materials thicker than 0.05 in. On lighter material, ACHF should be used for best weld results. Where welding rod is required, ERCuSi-A Silicon Bronze Rod is recommended.5. ALUMINUM BRONZE(a) General: No flux is required; ACHF will produce the best weld results; a forehand welding technique,with an aluminum bronze rod should be used. Aluminum bronze rod also provides good wear-resistance surfaces when deposited on steel, cast iron, copper, and other metals. this is from wikipedia.... Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion. They are also resistant to corrosion in sea water. Aluminium bronzes' resistance to corrosion results from the aluminium in the alloys, which reacts with atmospheric oxygen to form a thin, tough surface layer of alumina (aluminium oxide) which acts as a barrier to corrosion of the copper-rich alloy. The addition of tin can improve corrosion resistance.[1] Another notable property of aluminium bronzes are their biostatic effects. The copper component of the alloy prevents colonization by marine organisms including algae, lichens, barnacles, and mussels, and therefore can be preferable to stainless steel or other non-cupric alloys in applications where such colonization would be unwanted. Aluminium bronzes tend to have a golden color.🧑‍🏭🧑‍🔧🛳🚢

@benz-share9058 2 года назад

Aluminum bronze is significantly stronger and the weld has more of a shiny gold color. Because of the aluminum, it's usually welded with AC rather than DC. I believe it has higher elongation before failure. I've used both, but only with the TIG process. Both are good for brazing, and thus for connecting dissimilar materials or when you want to keep temperatures and heat input down. Some people favor pulsing when brazing with these two fillers, and that is somewhat more typical of TIG than MIG machines.

@ypaulbrown 2 года назад

@@benz-share9058 thanks for responding, that is some great information. When running these alloys with MIG [GMAW OR MAG] you are welding with 100% DC electrode positive so you have maximum cleaning action with the argon gas, so there is no reason to run with AC, and MIG is not known for running very well with AC, at least in the information I have read.

I have to say you nailed it for sure. Covered all points on the topic at hand. There's a saying "Paul you are the man." Look forward to see more great videos on RU-vid. One comment I can think of, the grounding trick is great, I prefer to use a c-clamp grounding clamp. Well done and peace too.

I also use a C Clamp ground[work] clamp when I can, but the table in the studio would hide it and I wanted to show that great MIG grounding technique......it really does make a big differance.....and it works great for TIG and Stick......just a short piece of welding lead....will last for years, you can even use a copper Brillo [Scrub] pad......glad you liked, Paul

I do a bit of silicon mig on duragal security door. Works quite well just have to remember to move slower to avoid underfill. I may have missed it in the video, but should warn people that silicon bronze is pretty nasty stuff. I mean should wear ppe for all welding but especially silicon bronze should have a mask on and as much ventilation as you can get!

@ypaulbrown 2 года назад

This is from the Harris Products MSDS, you may have noticed I mention not wearing a respirator due to the good ventilation we have at the studio, and also keeping my head out of the fume plume, [2 Hazard(s) identification Classified according to the criteria of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), OSHA Hazard Communication Standard (29 CFR 1910.1200) and the Canadian Controlled Products Regulations. · Classification of the substance or mixture The product is not classified as hazardous according to the Globally Harmonized System (GHS). · Additional information: There are no other hazards not otherwise classified that have been identified. 0 % of the mixture consists of component(s) of unknown toxicity] you may be confusing Silicon Bronze with Beryllium Copper, which is very hazardous Thanks for watching and commenting, Paul

Don, yes you could weld cast iron, aluminum bronze would be better though, you would still have to preheat the cast iron to at least 350 F degrees, and 5 to 6 hundred would be better with a slow cool down, there are some good videos on the channel on welding cast iron, one was posted last week actually, thanks for watching and commenting, Paul

@kf8575 2 года назад

@1:38 you seriously need to adjust your parameters, that over-roll on the bottom side of the fillet is no good at all. Also, the galv was burning off, could see the arc changing colour, and fumes coming off.

@ypaulbrown 2 года назад

good point, K F, since it is an adhesive weld and not a fusion weld, the weld size is much larger and is still stronger than the base material. Unfortunately, we only had enough time to do one take and setup in the studio that day......next time, we will make sure to not have any overlap, Thanks for commenting and viewing.....Paul

@ypaulbrown 2 года назад

the color of arc is due to the 95% copper which gives it a green arc. as far as the zinc burning off, there is some zinc in the filler wire and zinc boils at 1,665 degrees f or 907 C, not all the zinc is vaporizing, even when doing a fusion weld with steel filler, there is some zinc co-mingled in the weld pool to give the weld galvanic protection. all welding will have some fumes coming off, when working with an arc that is 10,000 degrees, something is going to smoke.....hope this helps, Paul

@tommyobrien9480 2 года назад

I wonder if you could do this to join aluminum to Copper? Right now lithium battery terminals are welded using lasers which is out of reach of normal people. All lithium batteries have an aluminum terminal and a copper terminal. If this works to join the aluminum tabs of one cell to the Copper tabs of the next cell this could revolutionize home built battery packs.

@@ypaulbrown Of course! I forgot that MIG is electrode-positive (I pretty much only use TIG) and so the vast majority of the heat goes to melting the electrode. Benefit is less heat to the base material, but that lower heat may be why a little extra voltage is needed for MIG to cause the puddle to fully wet to the base material.

hey Mike, the silicon bronze is rather sluggish and has problems wetting out.....you are correct saying they look like crap, but they do hold the material together. they might have been better looking if we had run a tig torch over them.....there were no second takes while shooting the video and that would have helped in my opinion also as we did not take the time to do any testing due to scheduling. and just gave it a go......the idea was to show how GMAW [MIG/MAG] welding can be done and what it is used for.
