Cost : Soldering is a cheap process. Brazing is quite costlier. Preheating : Preheating of base metal does not require in soldering. Preheating requires in brazing. Types of metals : Soldering is possible only in similar sheet metals as well as thin metals.
Brazing is suitable in similar or dissimilar as well as thicker metal parts. Difference of soldering and brazing in tabular form: Summary of brazing and soldering Both brazing and soldering are the common methods of joining two or more similar or dissimilar metals using filler metals.
Both of the methods are similar to each other, the basic difference is that soldering process is done using filler metals less than the temperature of 0 F. Soldering is mainly used in electronic industry for joining electronic wires and components and brazing is mainly used to join all kind of metals in industry such as automotive industry.
It takes comparatively more heat than any other soldering process. Silver Solder is used with a Flux, which chemically cleans the metal and keeps it clean during the Silver Soldering process. Silver Solder is also know as Silver Brazing. Braze on the other hand, does not get drawn into the joint, but is built up on the surface of the metal being joined, so it looks more like a weld. Like Silver Solder, the Braze material bonds with the surface of the metal being joined.
Braze is used with a Flux, which chemically cleans the metal and keeps it clean during the Brazing process. Brazing is also known as Bronze Welding. Most Silver Solders can be categorised by their Silver content. The Silver content will determine the fluidity and melting temperature, the more Silver, the more fluid and the lower the melting temperature.

Please let me know what you thought of this article by leaving a comment. Hi Graham, I am in the startup phase of sourcing materials for an aircraft project. The fuselage around 2 metres long will be made using a variety of stainless steel tubes of 0.
I hope to be able to form a small flange to assist in strengthening the joints, but will be small. Would you suggest braze or silver solder? Overlapping type joints will be necessary as you cannot build up Silver Solder to create a weld looking joint.
Once this happens you will not be able to get Silver Solder to bond, the only course of action is to remove the bluing and start again. I would strongly suggest practice!!! Hope that helps. Good luck with what sounds like an interesting project. I want to silver-solder a folding handle onto a stainless steel thin-wall vessel weighing about 15kg. I wonder how the pull-strength of the silver-solder joint varies with the alloy?
Where can I look up the tensile strength of the silver-solder alloys? Then it should be easy for me to calculate the pull strength of the joints.
Hi Jerry Thanks for reaching out. Cheers Graham. I hand a bent clock hand so without annealing… I now have two bent clock hand parts the clock hand is two hundred or so years old difficult to find the correct type so do I silver solder or braze, the hands are latticed so looking at 1x1mm square x2 joints same clock bell gear stripped three teeth so looking at insert and then hand profile teeth. Insert i would be happy to just silver solder in a new section but the hand I do not think silver solder is the way to go as it is the minute hand and my only way to correct the time 12 or more times a year.
The hand in question Hi David Difficult to offer specific suggestions without being able to see the job. But things to consider in the process of deciding whether to Braze or Silver Solder are:. Adjusting the clock via the first mm would seem a sensible way to go, but it all depends on the strength of joint that can be achieved and how much effort is needed to move the Hand to adjust the clock. Thx for that. Thank you. Would silver solder be strong enough? Hi John Silver Solder relies on surface area and a tight joint for strength.
US: 1 info fusion-inc. Home » Brazing » Silver Brazing. At its liquidus temperature, the molten filler metal interacts with a thin layer of the base metal, cooling to form an exceptionally strong, sealed joint due to grain structure interaction. The silver brazed joint becomes a sandwich of different layers, each metallurgically linked to each other.
Silver brazing uses filler metals and alloys such as silver, copper, zinc, cadmium, etc. Flux is necessary for brazing to remove and prevent reformulation of surface oxides on the base metals.
