Learn the Basics of Orbital Welding

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…

A Review of 5 Common Welding Defects

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….

Welding With Brass

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…

An Overview of Ultrasonic Welding

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…
