Just read Tubal Cain's "Soldering and Brazing" Going to buy some low-temp silver solder. Tried MSC, Enco, JTS, and McMaster-Carr, Midway, and Midwest. The...
Oh. This is wonderful! Good stuff! I have a Miller 210 with the spool gun. I want to start welding some aluminum plate. I'm doing OK with steel. How do I...
I buy my silver solder at the local welding supply shop. They grade it by th percent silver content, not melting temperature. Check the catalogs you...
There is a BIG difference between low temp silver bearing solders and "real" silver solders. Basically, there are 3 grades, easy, medium and hard. Below is a...
I have a 1985 lincoln DC-250 with an LN-7 wire feeder. It worked well for a long time then I move, and stored in for the last 4 years unused. Now when I try...
Go visit Cal poly. they have two campuses: one inpomona if you don't want to leave the LA area the other in San Luis Obispo. THey have an open house in the...
Depends on your definition of successful. Yes you can weld it and not have a crack. No it will not have the properties of 400 SS anymore. It will be a new...
I have a finely machined part that I need to repair. Looks like the part could be repaired using silver solder except for probable heat damage to the...
Dan, If I am understanding your question correctly. I would coat the machined surface with the same flux that you are using to braze the part. Or coat the...
Back in the day (20 years ago) when we were making jewelry (silver mostly) as a hobby (no casting, all forging and soldering), there were some products that...
I don't see how the heat from silver soldering would do much damage. There is a product called "Hot Stop". If you do a search on "hot stop paste" or "heat stop...
Regular normal white (old fashioned) toothpaste will do it, but there are pastes that shed the heat even better, but very expensive. With silver jewelry I...
... Another tool is furnace brazing in an inert atmosphere. This allows the part to be slowly brought to temperature in a jig and then slowly cooled back...
Thanks to all who responded . I would love to have one of those electric heat treating furnaces but Hi tech to me is reading the colors on iron as they run to...
If you are only concerned about oxidation and not warping, and I'd think that oxidation would be your only concern with silver soldering, then Google "Pripps...
Try Harris paste flux. It is brazing flux (borax with chlorides) disolved in water (or alcohol). Ultrasonic or clean the piece to degrease it or the flux...
If you are only concerned about oxidation and not warping, and I'd think that oxidation would be your only concern with silver soldering, then Google "Pripps...
The Harris Stay-Silv is what I keep in my stock. So far as warping is concerned, this a fairly small part around a pound, if that, and it is almost cubic in...
Just an observation: Finely machined parts will warp if unevenly heated, quickly heating and cooling the parts will cause forces due to uneven internal...
Hi, Does anyone know the pros and cons of using .045 NR211, ER70S-6 and 7018 electrodes for welding on trailer hitches? I'm pretty sure you can't go wrong with...
A couple of things; solid wire can run in the short circuit or spray transfer mode. The difference is the parameter levels and gas mix used . The short...
The "Pripps" is to protect the area you are not soldering from oxidation and it works great and cleans up much easier than the Harris flux! Use your Harris...
I have been reading all the replies, I have the feeling that welding or brazing is not the way to go. Why not clean the broken surfaces carefully and use a...
Hi to all, I m Alan looking to find out where i can get a pub type co2 bottle exchanged or refilled, or even an c02 argon mix....I m jumping the gun a bit as...
