Video about silver brazing carbide inserts

admin

I've searched on you tube about this and only found about brazing saw blade tips.Some here are producing some really cool videos.Could someone here take the time to do a small video with the right way to do it.I have some 56% silver brazing rods.Like I said in the past, I'm maybe 90% machinist and 10% welder, but I like welding as much as machining.Thanks a lot.Jeff

Reply:56% silver will wet much much better on carbide. I would not use bronze. this is a great videoMike ZanconatoZanconato Custom Cycles @mzank on Instagram
Reply:50N is recommended for brazing inserts on holders.

Reply:You don't want to clamp it tight because there won't be room for the filler to flow. I would let gravity hold the bit and feed filler from one spot. If everything is at the right temp, the silver will flow through the entire joint. You can move the bit into final position once the flux settles down and gets glassy looking.Mike ZanconatoZanconato Custom Cycles @mzank on Instagram
Reply:How big is the insert and what is the size/shape of the base?Carbide saw teeth are a fairly simple, heat and go type of operation.  As the insert/base gets bigger/thicker, your process will need to change somewhat (I would preheat both the base material and the table as well as possibly change from wire to ribbon solder).BradFulcrum Saw & Tool
Reply:Best is to have sheet silver solder. They make it in thin sheets.  Cut a piece the right size. Flux both pieces. Lay them together. Heat till it flows. Use a small rod or the like to seat the insert where you want it. Let cool.   Otherwise you can try to flow it in with it floating. It's a bit tricky but doable.   Another method would be to coat both surfaces with solder before putting them together. Let cool. Clean and flux. Then stack and heat.Millermatic 252XMT 304'sDynasty 280DXHypertherm PowerMax 1250Miller Trailblazer 302 EFIOptima PulserXR feeder and XR Edge gun and more athttp://members.dslextreme.com/users/waynecook/index.htm
Reply:Made hundreds of soldered tipped tools back in the day, company I worked for at the time made their own, mostly 1-1/2" x 1" shank.What I did was applied flux to the milled recess, cut a small piece of sliver solder, laid the insert on top, held in place with a rod, applied heat with O/A. When the temp is right the insert will drop into place with a good bond.
Reply:I've done a fair share of these.   i used to braze them on top of cup teeth on trenchers ( ditch witches)    Bronze works great, it holds them on the tip of a tooth while it's pounding into the earth.   Most carbide inserts are coated these days.   If you don't get the coating off, the braze job wont hold.   At least not for what I was doing.  I used to try to crack them in half, that was my fast way of having a surface w/o the coating.   Believe me, the coating is your enemy.  Problem was, there is no good way to crack them.  The stuff is so hard, it ruins your vise haws and pits your hammer.   Anyway, I decided it was cheaper to buy new uncoated carbide in a tubular round form.    Like someone mentioned earlier, don't clamp tight, and add lots of granular flux beside the flux on your filler rod.
Reply:Thanks everybody, will try to find some thin silver solder.I don't need to do these very often because I have a lot of indexable lathe tools but this sometime a good thing to know.Thanks again.Jeff
Reply:I have hammered wire flat to get thin pieces. But if you can get it to sit there you can just lay it on top of short pieces of cut wire.  Sometimes you've just got to work with what you've got.Millermatic 252XMT 304'sDynasty 280DXHypertherm PowerMax 1250Miller Trailblazer 302 EFIOptima PulserXR feeder and XR Edge gun and more athttp://members.dslextreme.com/users/waynecook/index.htm
Reply:When I silver brazed carbide back in the last century we used precut  silver sheets and a induction solder machine . had some kind of flux on it that we has to sandblast off in a water jet type machine.
