There are two basic types of soldering: hard and soft. Hard soldering typically uses a silver mixture and is good for projects such as jewelry making because it provides a strong joint.
Soft soldering uses other types of metals and costs less to perform. It can be used on items like radios and televisions and provides a suitable bond that is strong enough to withstand normal wear and temperatures that are not too extreme. However, this type of soldering still uses lead on a regular basis and is posing a threat to local water supplies.Learn more about Crafting
