Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used.
What is soft soldering used for?
Soft Soldering. Soft soldering is a useful process for joining metals of many types, particularly small intricate parts which might get deformed or damaged with higher temperature processes. The process described here uses a gas torch as the heat source.
In what situations would you use hard soldering instead of soft soldering?
Hard Solder is Stronger
Hard soldering creates a stronger bond compared to soft soldering and involves higher temperatures to melt the solder material. This material is normally brass or silver and requires the use of a blowtorch to melt.
