HS v2022 Code: 831110

About electrodes; coated, of base metal, for electric arc-welding

HS code 831110 covers the import and export of coated electrodes made of base metal, primarily used for electric arc-welding. This industry plays a crucial role in the broader manufacturing and construction sectors, as these electrodes are essential for joining and fabricating metal components. The demand for these products is closely tied to the health and activity levels of industries such as automotive, shipbuilding, and infrastructure development.

Production process

The production of coated welding electrodes typically involves a multi-step process. First, a core wire made of mild steel or other base metal is drawn to the desired diameter. The core wire is then coated with a layer of flux, which can consist of various minerals, alloys, and binding agents. This coating helps to stabilize the arc, shield the weld pool, and improve the overall quality of the weld. The coated electrodes are then cut to the appropriate lengths and packaged for distribution.

Production inputs

The main inputs required for the production of coated welding electrodes include the base metal wire, flux materials, and specialized manufacturing equipment. The base metal wire is typically made of mild steel, but can also include other alloys such as 720720 Nickel-chromium alloys or 720810 Stainless steel. The flux coating can be composed of a variety of minerals, including 252100 Limestone and 281800 Magnesium oxide, as well as binders and other additives. The production process also requires specialized welding equipment, such as wire-feeding machines and ovens for drying the coated electrodes.

Production outputs

The primary output of this industry is the coated welding electrodes, which are then consumed by various manufacturing and construction industries. These electrodes are used in a wide range of applications, including 842121 Machinery for filtering or purifying gases, 870120 (Tractors (other than tractors of heading 8709)), and 940320 Metal furniture. The welding electrodes produced under HS code 831110 can also be used in the production of other 831120 Welding rods and cored wire, of base metal, for soldering, brazing or welding by flame.
