Frequently Asked Questions (FAQs)
1. What was solder used for?
Solder is commonly used to bond metal workpieces together in various industries such as electronics, heating, air conditioning, mechanical systems, fire sprinklers, radiator manufacturing, repair, sheet metal work, jewelry, and stained glass work.
2. Is solder as strong as welding?
No, soldering does not produce as strong of a joint as welding. Welding is suitable for load-bearing and structural metal connections, while soldering only creates a connection as strong as the solder used. Welding different metals together may require specialized equipment and techniques.
3. What is the golden rule of soldering?
The golden rule of soldering is to ensure that the area to be soldered is clean, dry, and free from grease. It is recommended to clean the area with a solvent if necessary and abrade the metal surface to remove oxidation. The metal should be bright and ready to take the solder. Additionally, a suitable flux should be used to prevent new oxidation from forming when heating the metal.
4. What material does solder not stick to?
Solder does not stick to all metals. For example, it will not stick to aluminum. However, with compatible metals, solder can be used by preparing the metal surface to remove oxidation and using a suitable flux. The flux helps prevent new oxidation from forming when the metal is heated.
5. Will solder weld to steel?
Soldering steel can be more challenging than soldering carbon steel due to the presence of a tenacious oxide film on stainless steels. However, with correct techniques and proper preparation, stainless steels can be successfully joined by soldering. It is important to note that the joint strength of soldering is generally lower than brazed or welded joints.
