FAQ
Frequently Asked Questions
In American English, yes, it is typically silent (pronounced 'sodder'). In British English, the 'L' is pronounced.
Soldering joins metals using a filler metal (solder) that melts at a lower temperature than the base metals. Welding melts the base metals themselves to fuse them together.
For small electronics, a soldering iron is essential. For larger joints, like in plumbing, a propane torch can be used to heat the metal and melt the solder.
Due to health and environmental regulations (like RoHS), lead-free solder alloys are now standard in commercial electronics to reduce toxic lead waste.
