At first glance, Monel® (a trademark name that refers to several different alloys) looks a lot like chrome-molybdenum steel, and there are some overlaps in how these alloys are used, for instance, in highly corrosive environments. However, Monel is a nonferrous alloy of nickel and copper with some unique properties….

Tungsten has the highest melting point of all metals at 3422° C (6192° F), has three times the density of steel, and is the favorite metal of those who want to punch large holes in objects. However, tungsten can also create as well as destroy, and these properties make it…
Many welders don’t pay as much attention to the guidelines laid out by the U.S. Occupational Safety and Health Administration (OSHA) as they should. In part, this is because of the sheer number of OSHA regulations that exist. This makes it difficult to determine which, if any, OSHA welding safety…
Every weld receives a visual inspection. It could be as simple as the welder looking at the weld and deciding that it’s fine. However, the term “welding visual inspection” generally refers to a formal qualification process designed to certify the weld and catch unsatisfactory welding. In pipe work, the finalized…
When comparing welding methods for pipe and tubing, it’s clear that orbital TIG welding offers quantifiable advantages over manual welding, particularly for repetitive, high-volume welding applications or in situations where access to the pipe or tube is obstructed. For these applications, orbital welding methods deliver consistent weld quality and accomplish…
The needs of a project are what define an acceptable weld, and those needs, in turn, are defined by the end-user with guidance from various resources, codes, standards, and government regulations. Depending on the industry and region, many standards and regulations may apply to a project. Highly specialized projects like…
The repetitive task of surface hardening is usually thought of as a punishment by most welders, but this welding process fulfills an important role. It is most often used to build up the contact surfaces of heavy equipment after use has worn them down. Surface hardening is also used to…
One of the few constants in this world is the deadline. Whether a project is in manufacturing, construction, or facilities maintenance, it will have a date by which it must be completed. One major factor in whether or not a project is completed on time is the deployment of skilled…
Shielded Metal Arc Welding (SMAW), also known as stick, is generally the default welding process for pipe. A simple internet search for pipe welding yields countless images of welders using this process along with many tutorials on how to weld pipe correctly using stick welding. However, in spite of its…
Welding in the overhead position—with the workpiece directly above the welder—is widely thought to be the most difficult welding position. Pipe welding is also well known to be particularly challenging welding work. The perception that both are especially difficult types of welding is born out by the fact that each…
