Is brazing stronger than soldering?
Properly brazed joints can be stronger than the pieces being joined, but are not as strong as welded joints. Brazing also has minimal effects on the two metal parts. Soldering is a low-temperature analog to brazing.
Alloys commonly used for electrical soldering are 60/40 Sn-Pb, which melts at 188 °C (370 °F), and 63/37 Sn-Pb used principally in electrical/electronic work. 63/37 is a eutectic alloy of these metals, which: has the lowest melting point (183 °C or 361 °F) of all the tin-lead alloys; and.
- The melting point of most solder is in the region of 188°C (370°F) and the iron tip temperature is typically 330°C to 350°C (626°F to 662°F). Soldering Basics: Although tip temperature is not the key element in soldering you should always start at the lowest temperature possible.
- The typical reflow temperature range for Pb-Free (Sn/Ag) solder is 240-250°C with 40-80 seconds over 220°C. It should be noted that the recommended Sn/Pb reflow temperature range are less critical, and that minor deviations in temperature of equipment and components generally do not create soldering problems.
- Which property of solder makes it suitable for welding electrical wires ? Accepted Answer: Solder is an alloy of lead and tin. It is used for welding electric wires because of its low melting point.
