The TIG (or Tungsten Inert Gas) welding process uses non-consumable tungsten electrode which passes the current to welding arc. This Tungsten Inert Gas Welding process is also known as Gas Tungsten Arc Welding or else by the first letters GTAW. The tungsten and other hot materials are protected by inert gas by the cooling effect.
Tension leveling is the process of pulling the strip beyond its yield point to permanently change the shape of the strip and make it flat. The material is run through an entry and exit set of bridle rolls, with the corrective leveler located between them. If you have an edge wave, the concept is to
At American Steel, customers often ask us about the differences between hot rolled steel and cold rolled steel. Fundamentally, there are some differences between these two types of metal. The differences aren’t related to the product specification or the grade but in the way these metals are processed at the mill. Knowing the differences between
Tube mills produce pipe and tube by taking a continuous strip of material and continuously roll forms it until the edges of the strip meet together at a weld station. At this point, the welding process melts and fuses the edges of the tube together and the material exits the weld station as welded tube.
