Shielded Metal Arc Welding (SMAW)
Shielded Metal Arc Welding is also known as “SMAW” or as “stick welding.” The stick in question refers to the electrode, which is coated in a protectant flux. An electrode holder holds the “stick” in place and an electric arc is created using either direct or alternating current. This in turn causes the electrode to slowly melt away while also melting the metals to be joined. At the same time the flux coating releases a gas vapor which, together with the slag, creates a shielded environment to protect the weld area from contamination.
Gas Tungsten Arc Welding (GTAW)
Gas Tungsten Arc Welding, also known as “GTAW” or “TIG welding” uses a tungsten electrode to produce the weld. Unlike SMAW welding the electrode is not consumed during the welding process. Instead the weld area is protected from atmospheric contamination by an inert gas, often Argon or Helium gas. The acronym “TIG” refers to “Tungsten Inert Gas.”
Gas Metal Arc Welding (GMAW)
Gas Metal Arc Welding, also known as “GMAW” or “MIG welding” uses a consumable wire electrode that is fed through a welding gun. An inert shielding gas such as Argon or a mixture of Argon and Carbon Dioxide is also sprayed over the welding puddle to protect it from contamination. MIG welding has become the most common welding method in industrial settings because of its versatility and relative ease. However, it is not ideal for use outdoors or in other areas with high air volatility.
Flux-Cored Arc Welding (FCAW)
Flux-Cored Arc Welding, or “FCAW,” is very similar to MIG welding; however, it features the use of a special tubular wire that is filled with flux. The flux may be sufficient by itself to protect the welding puddle from contamination or a shielding gas may also be used, depending on the filler material and other circumstances.
By heating a silver alloy we are able to join together two metals made of separate materials. As long as the metals being joined have a higher melting temperature they can be brazed or soldered together, allowing for hard metals such as steel, stainless steel, copper, brass, and many others to be combined. The joints produced through these methods are sealed, strong, and leak proof, and are able to stand up to the harshest of conditions. The brazing process can even join certain non-metals like metalized ceramics and produces less thermal distortion than welding.
Stellite Welding and Hardfacing
Stellite is a variety of cobalt-chromium alloys that also may contain tungsten, molybdenum, and small amounts of carbon. Stellite is known for its strong resistance to wear and ability to perform in even the most extreme of environments. We have the capabilities to both weld pieces of this “superalloy” as well as hardfacing it on the surface of other materials in order to make them stronger and more resilient.
