Welding is, at its core, simply a way of bonding two pieces of metal. While there are other ways to join metal (riveting, brazing and soldering, for instance), welding has become the method of choice for its strength, efficiency and versatility. There are tons of different welding meth...
Soldering is the process of using a filler material (solder) to join pieces of metal together. Soldering occurs at relatively low temperatures (around 400 degrees Fahrenheit) as compared to brazing and welding, which actually melt and fuse the materials themselves at higher temperatures. In solderin...

Metal contacts connect the wiring to the halves of the tip. The tip is as important to the tool's abilities as the circuitry. We'll examine the tip, including what it's made of, next. The Cold Heat Tip Solder: burninated. Tip: broken. The original marketing materials for the Cold ...
The most common method of making magnets today involves placing metal in a magnetic field. CRStocker/Shutterstock To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needl...
people have been using currency for the exchange of goods. Before the advent of coins, the exchange could have been in the form of ax heads, jewels, pieces of fabric, and even shells. Around 650 BC, metal coins began to appear in Western Europe; these were small ingots of a specific ...

An MOV has three parts: a piece of metal oxide material in the middle, joined to the power and grounding line by two semiconductors. These semiconductors have a variable resistance that is dependent on voltage. When voltage is below a certain level, the electrons in the semiconductors flow in...
Plumbing pros recommend a non-hardening sealing paste. After applying the paste, hand-tighten the fitting until snug, then tighten one to two more turns at most. This is all that’s required for a stress-free connection that won’t leak. Avoid using a wrench if possible. ...
