Difference Between Soldering and Brazing


Main Difference

The main difference between Soldering vs. Brazing is that Soldering is a technique of fitting together similar or dissimilar metals through a filler metal whose liquid temperature is high, and Brazing is perfectly suitable for fitting together of dissimilar metals and done at relatively low temperature.

Soldering vs. Brazing

Soldering is one of the eldest procedures of joining metals that lets electrical parts to be electrically joined, for instance, wires or cords, capacitors, regulators, etc. It also uses an additional material or filler metal named solder to fill the joint which makes an alloy or composite at the metal surface but the parent metal not melted. Whereas Brazing is a joining procedure used to join two parts of metal together employing a metallic filler that has been heated or melted and streamed into the joint. The soldering method uses filler alloys with melting temperatures under 450 °C (840 °F), while brazing mostly completed at a temperature above 450 °C but under the critical temperature of the metal. Soldering is the procedure typically used in mechanized production to form a lasting joining among the electronic parts, and brazing used in automotive productions. In brazing flux is used to stimulate moistening and to take out oxides from the base or parent material so that the adjunct metal attachments well with the metal parts. Soldering used in pipeline fittings, electronics, handiwork, engine maintenance, and metal works from irregular or flashing to ornaments. It is generally used to link wires to leads of workings such as switches; on the other hand, brazing is generally used to link all types of metals excluding aluminum and magnesium.

What is Soldering?

Soldering is a method in which two or more objects are linked together by smelting and placing an additive material into the joint, the additive metal having a lesser melting point. Soldering is a major method in the making of electronic tools. Soldering permits electronic components to be coupled electrically and also found in place. Therefore soldering is at the center of electronics production and manufacture for the collector and supporter or student along with for business establishments manufacturing electronic tools on a large scale. While soldering utilized in a range of different businesses as well as the sanitation business, used to join pipes and seal or cover them to stop water leaking out, and it used in the jewelry business between others, it is basic to the electronics manufacturing. There are diverse methods used for micro scaled and mass scale soldering. Labor-based schemes cannot use for huge scale production, where a high level of mechanization is required to deliver the output needed. Whereas small-scale manufacture for commercial initiatives requires soldering systems that do not need the large scale capital and set up required for bulk production.

What is Brazing?

Brazing is a method for connecting two portions of metal that comprise the utilization of heat and the adding of filling metal. This assistant material, which has a minor temperature of melting than the metals to be allied, moreover pre-arranged into the link as the portions or parts are heated — the temperature of the liquefied stuffing or filling be used brazing over 800° F (430° C). Brazed links or joints are generally more solid than soldered links. Brazing can be carried out or done on most metals, and the variation of current brazing mergers is increasing as new blends, and new provision desires introduced. Heating by the torch in the air is suitable, delivered the joint effectively fluxed. A comprehensive brazed joint can attain by the filler and parent materials should be metalwork well-matched, and the joint design should combine a gap into which the melted braze plaster or filler derived by wick or capillary forces. The imperative or needed combined gap is reliant on many aspects, comprising the brazing atmosphere and the structure of the base substantial or material and brazes alloy.

Key Differences

  1. Soldering is used to link two or more metal things together through filler solder material, and brazing distinct as the connection of two or more metal things to produce a combination of material.
  2. Whereas soldering accomplished at a temperature lower than 200°C, and brazing accomplished at temperature preceding 450°C but under the risky or critical temperature of the metal.
  3. Soldering is assisted in electronics industries to a combined capacitor, resistor, wire, etc. to the electric hobs. While brazing assisted in mechanical industries to different joint metals.
  4. Soldering junctions are poor or weak than brazing junctions. And brazing provides a harder or powerful joint.
  5. Soldering is a cheaper process; on the other hand, brazing is a costly process.
  6. The soldering procedure is very lean and easier to mechanize, while brazing is not so easier for mechanization, completed at automotive productions.


Equally soldering and brazing is the two more popular procedures used for connecting two or more parts of similar or dissimilar metals. Soldering uses filler compounds with melting temperatures under 450 °C (840 °F) while brazing performed at temperatures overhead 450 °C.
