Welded Metal Tube - Grade 904l, Length Options: 3m, 6m, 18m, Sizes: 1/2 Inch, 1 Inch, 2 Inch, 3/4 Inch | Galvanized Surface, Astm/asme Tolerance, Ideal For Oil And Gas Control Lines

Welded tubes are a type of structural metal tubing that has a weld seam along its longitudinal axis. It can be made from essentially any type of metal or metal alloy that can be welded such as carbon steel, stainless steel, low-alloy steel, and aluminum. Welded metal tube is typically available in the following shapes:

Round
Square
Rectangular


Used to Make Welded Tube?
Electric Resistance Welding (ERW)
High Frequency Welding
Laser Beam Welding
Gas Tungsten Arc Welding (TIG welding)
Plasma Arc Welding
Submerged Arc Welding


Used to Manufacture Welded Tubes?
There are many reasons why one welding process may be chosen over another to manufacture welded tubing. Perhaps the most common method is high frequency welding. To use high frequency welding to make welded tube, a high frequency welding power source activated . Once the power source is activated, leads from the power source which are placed in close proximity to the formed but unwelded tube begin to emit high frequency energy. This energy excites the molecules in the tube until a temperature level at which they can be joined is reached. At this point the two heated edges of the unwelded tubing are forced together through another die and a weld is made.
