When would you use hard soldering instead of soft?
When would you use hard soldering instead of soft?
Temperature Range Solder alloys with melting temperatures below 840°F are considered to be soft and any soldering done above 840°F is referred to as brazing or “hard soldering”; also called silver soldering when a silver alloy is used.
What is an example of hard solder?
In some cases, when someone uses silver as the solder material, hard soldering may be referred to as silver soldering. Although silver melts at a lower temperature compared to brass, it is more expensive. Use hard soldering with silver solder when joining pieces of copper, brass or silver.
What is hard soldering process?
Hard soldering means soldering with solders of a liquidus temperature that lies above 450 ° C. In practice, the operating temperature is higher than 600 ° C. Hard soldering differs from welding in that: The melting temperature of the solder is lower than that of the base material.
Where is soft soldering used?
The filler metal melts and joint is created. Soft soldering is carried out at much lower temperature than silver soldering. Soft soldering is best suitable where the joint is not exposed to high heat and vibrations. Soft soldering is used for joining metals in connecting valves and electronics components.
What is an example of soldering?
Small mechanical parts are often soldered or brazed as well. Soldering is also used to join lead came and copper foil in stained glass work. Electronic soldering connects electrical wiring to devices, and electronic components to printed circuit boards. Electronic connections may be hand-soldered with a soldering iron.
What does hard soldered mean?

Is silver solder hard solder?
Our Hard Silver Solder is perfect for Sterling Silver Jewelry making and repairs. It's high temperature melting point of 1,365°F (741°C) results in strong, solid Solder joints, and is recommended for more experienced Jewelers.
What are the 3 types of soldering?
In summary, there are three main types of solder: lead-based, lead-free, and flux.
What is soft soldering?
Soft soldering is characterized by having a melting point of the filler metal below approximately 400 °C (752 °F), whereas silver soldering and brazing use higher temperatures, typically requiring a flame or carbon arc torch to achieve the melting of the filler.
Which are the two types of soldering?
- soft soldering, which originally used a tin-lead alloy as the filler metal.
- silver soldering, which uses an alloy containing silver.
- brazing which uses a brass alloy for the filler.
What is the difference between soft soldering and brazing?
Temperature Range The main difference being the temperature! Solder alloys with melting temperatures below 840°F are considered to be soft and any soldering done above 840°F is referred to as brazing or “hard soldering”; also called silver soldering when a silver alloy is used.
Is brazing a hard soldering process?
Brazing is similar to hard soldering because the pieces of metal being bonded together are heated, but not melted, during the bonding process. Once you have the base metals heated, place solder material, called brazing filler metal, between the surfaces, It instantly melts.
Is soldering the same as brazing?
We receive many questions about the difference between soldering and brazing. The American Welding Society (AWS) defines brazing as such a process which involves a filler metal which has a liquidus above 450°C (842°F). Soldering, on the other hand, involves filler metals with a liquidus of 450°C or below.
