The majority of soldering guns and irons are used to join electrical wires, which requires less heat. Those tools just do not heat up sufficiently to melt bigger jewelry metals. Sterling silver has a melting point of 1640 degrees Fahrenheit, or 893 degrees Celsius. Only the most powerful soldering irons can reach that temperature.
The tip of the iron becomes very hot when you turn on the power supply. Because silver is such a good conductor, even though the body of the iron stays cool, the tip gets hot very quickly. Once you put some silver in your furnace, you would better leave it there until it melts down or runs out of energy!
The metal fabricator should be aware that if any part of an object contains silver, then the entire object should be considered toxic. Even if you follow all the safety procedures, someone could still be hurt by contact with this material. You should never eat, drink, or breathe while working with silver objects. These are just some of the many dangers we risk every day by using metals for jewelry. It is important to use caution and common sense when working with metals!
Because gold has a rather high melting point, melting it with a soldering iron will be difficult. To effectively solder a gold product, you will require a heat source capable of producing high-temperature levels. The gold may simply burn if you attempt to seller it using a regular iron.
The best way to solder gold is with a torch. Otherwise, use silver solder to help protect the gold from burning while it melts.
Soldering irons are available in gold or silver. Both have their advantages and disadvantages. A gold soldering iron can withstand higher temperatures so it's good for welding components made of copper or aluminum together. Silver soldering irons work better at lower temperatures which is important when working with delicate materials. Either one can be used to solder jewelry provided you take into account the differences between the two metals.
When soldering gold, wear protective gear. A face mask is recommended because gold particles can get into your mouth and go down the throat. They won't cause any harm but they won't do any good either. Wear gloves to prevent gold skinning onto other objects. Finally, use with care! Gold is very precious and burns easily so be careful not to let it get away from you.
Most common metals, including mild steel, stainless steel, copper, brass, cast iron, and dissimilar metals, can be joined with silver solder. Because silver is a soft metal, the surface must be hardened before soldering to prevent damage to the article being joined.
The easiest way to join these types of materials is to use silver solder. Silver solder has lead removed from it so it will not poison you or your children if it gets into something you eat or drink. It is also non-toxic and won't break down into toxic substances over time.
There are two types of silver solder: pure silver and silver-based. Pure silver solder requires melting in a furnace at about 400 degrees F (204 degrees C) for several hours or using a torch to heat it directly. This process is expensive and not very practical for most people. The cheaper alternative is silver-based solder which can be bought in tube form and used like paint. It needs to be heated to about 300 degrees F (149 degrees C) to make it flowable. Then it can be applied to the joint as usual. After cooling, the piece can be cleaned with soap and water.
This is typical practice in many tinsmithing tasks, which is why a soldering iron is regarded as one of the most important tinsmithing instruments. A soldering iron is the equipment used to melt the solder that will be used to fuse the two metals. This device is 40% more powerful than the two types it replaces, making it ideal for soldering.
The tinman uses his soldering iron to join metal strips or sheets together to make containers such as soup cans or jars. He also uses it to attach objects such as nameplates and handles to these containers. The most common use of a soldering iron in tinsmithing is to fuse metal strips onto can ends or onto sheet metal upholstery fabric to make body panels. These body panels are then attached to the can bodies to finish them off.
The term "soldering" comes from Latin word "sodalicium", which means "solder". In fact, the first solderers were actually tin miners who needed a way to connect seams of metal ore together to form long strips they could work with. By heating the seam and adding molten tin to each side, they created a joint that held strong while they worked.
In tinsmithing, a soldering iron has two main purposes. First, it melts the solder that will bind the two metals being joined together. Second, it heats the metal above its melting point so that it can be worked on without burning your hand.
