Flux cored arc welding (FCAW) is an electric arc welding process that uses an arc between a continuously fed flux-filled electrode and the weld pool. The process is used with shielded gas from a flux contained within the tubular electrode with or without additional shielding from an externally supplied gas.

The flux cored and metal cored welding wires are commonly use in the off shore, pipe line, pressure vessels, ship building, earth moving equipment, rail car manufacturing segments and many others. They are becoming more and more popular within the robotic applications, for example in the automotive industry (cars, trucks, buses…) due to their higher deposition rate compare to the standard solid welding wires.

Tubular welding wires research and development are very active to further enhance the Submerged Arc Welding (SAW) process to obtain better mechanical properties of the welded joins, higher travel speeds with higher deposition rates than traditional solid wires. The tubular wire manufacturing process open a new window of opportunity to welding engineers for new wire and flux combinations to answer demanding customers.

Our Advanced Welding Wire Solution to produce tubular welding wire is composed of a strip pay-off, a tube mill line (forming, filling and closing stations), a rolling line (with micro cassettes) and a wire take-up.

ARC Welding Electrode

Arc welding is a process that is used to join metal to metal by using electricity to create heat enough to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes.

The welding region is usually protected by some type of shielding gas, vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated. First developed in the late part of the 19th century, arc welding became commercially important in shipbuilding during the Second World War. Today it remains an important process for the fabrication of steel structures and vehicles.

Welding Electrodes

Welding electrode E6013 is the most popular mild welding high titanium potassium type coating. It is able to provide excellent welding performance and satisfactory weld can be obtained in all position welding.

It is widely used in ordinary tensile strength mild steel structures especially suitable for intermittent welding to sheet steel and small work pieces as cosmetic welding with smooth and shiny appearance.

In arc welding an electrode is used to conduct current through a workpiece to fuse two pieces together. Depending upon the process, the electrode is either consumable, in the case of gas metal arc welding or shielded metal arc welding, or non-consumable, such as in gas tungsten arc welding. For a direct current system the weld rod or stick may be a cathode for a filling type weld or an anode for other welding processes. For an alternating current arc welder the welding electrode would not be considered an anode or cathode.
