Orbital Welding is an automated process where the electrode orbits (or circles around) the pipe or tube while the object to be welded remains stationary. An experienced and certified welder programs the welding machine which stores the welding schedule in its memory. The machine can be programmed for a specific travel speed, amperage, voltage, and…
Welding defects include any flaws that compromise the quality of the weld. They can be defined as occurring any time there is a deviation in the size and shape of the metal structure that affects technical and design requirements. A defect can occur at any stage of the welding process. They can be either internal or external….
In welding, not all metals are created equally. Some metals are in fact much more difficult to weld than others. Often times, metals have what is called poor weldability, making them less ideal to work with. Poor weldability is when there are only a limited number of welding processes that can be used on the…
Whether you are a novice at Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), or have trained and worked in TIG welding for years, you may be in the market for your own TIG welder. TIG welding is known for clean, precise and strong welds, making it a great option!…
Brass is an alloy of zinc and copper which can be joined with other metals to make various products. Many musical instruments are made of brass such as trumpets, trombones, French horns, and tubas. Orchestras and concert bands both have brass sections made up of these instruments. Other common items you may not realize are made…
Often times, the words welding and fabrication are used interchangeably because both are used to work with metals. While they include the bending, shaping and manipulation of metal, different tools and methods are necessary in each process. Some metal fabrication jobs require a welder while others do not. A welder might only play a part…
Ultrasonic welding (USW) uses high-frequency sounds that are generally not heard by humans but instead perceived as vibrations. These high-frequency sounds cause rapid vibrations within the materials to be welded. The vibrations cause the materials to rub against each other which creates friction. The friction in turn creates the heat needed at the contact area…
Brazing metals together is a process that is three centuries old. Its origin has been traced to Ancient Egypt. Archeologists have found small golden boxes and intricately formed jewelry made by brazing that dates back to 2975 B.C. These artifacts appear to be gifts made for Egyptian Pharaohs and are made mostly out of gold…
Tungsten Inert Gas welding, commonly referred to as TIG, is a welding process that uses a tungsten electrode to heat the metal that is being welded. The tungsten electrode carries the arc but is not consumed. An inert gas, like Argon, is used in the welding process as a shield to protect the weld from…
Purchasing welding equipment is a substantial investment and it’s best to do your research before making this purchase. The equipment you buy will last for years to come so it’s important to consider the quality, life span, repair and labor costs that your particular welding equipment will require. Let’s take a look at these points…
