Our crew at Industrial Motors & Machining Inc. provides top-quality welding and fabrication in the greater Denver area. We love this work and always enjoy learning more about our craft. Even though most folks don’t often stop to think about it, welding has played an absolutely pivotal role in the development of modern civilization. Here are five fun facts about welding. The Deepest Underwater Weld In 2005, the U.S. Navy set the record for deepest underwater weld, which was completed at 2,000 feet below the surface—twice the previous record. Space Welding In space, astronauts are able to use a process called “cold welding,” through which two pieces of metal instantly weld together when they come into contact. When in space, the metal automatically binds because there’s no oxidation in the way of the metals’ molecules. “Cold welding” in space first occurred in 1969. Welding is Used for Most Man-Made Products Over half of constructed products that go to market involve some type of welding. From personal computers to vehicles to home appliances, we constantly used welded products in our day-to-day lives. Superfast Ship Construction As World War II raged on, there was a need for warships to be completed at a much faster speed. Great resources were poured into large-scale welding projects, which led to the SS Robert E. Peary being built in just over four and half days. Ultimately, this ship was present for D-Day. The First Functional Industrial Robot General Motors employed the first functional industrial robot. In 1961, the robot, named Unimate, began work as a single-armed unit designed for spot welds. Unimate weighed more than 4,000 pounds and followed commands that were stored in an attached magnetic drum.

There are various types of electric motors that serve different purposes. Because electric motors exist largely out of sight, it’s easy to overlook their importance as they help us during our daily routines by powering machines such as home appliances, small electronics, and industrial equipment. At Industrial Motors and Machining, our local machine shop provides expert electric motor sales and service in the greater Denver area. Here’s a short overview of four common types of electric motors. AC Brushless Motors For successful operation, AC brushless motors depend on permanent electromagnets. To turn the stator and rotor in sync, they use induction of a rotating magnetic field. AC brushless motors are quite popular because they are easy to use and have many applications. Also, they make less noise and are easier to maintain than other electric motors. DC Brushed Motors DC brushed motors continue to be used for industrial purposes such as paper machines and steel rolling mills, though in some situations brushed motors are being replaced with brushless models because the brushes can wear down and necessitate replacement. With DC brushed motors, the brush orientation on the stator is what governs current flow. DC Brushless Motors DC brushless motors tend to be smaller than their AC brushless counterparts, making them excellent options for small spaces. These motors rely on an embedded controller for operation, rather than a slip ring or commutator. Linear Motors These motors, which generally feature greater speed and accuracy than rotary motors, generate linear force along the device’s length by way of an unrolled motor and stator.
