Welding Principle of ERW Steel Pipe

The emergence and maturity of high-frequency welding technology has directly promoted the huge development of the longitudinally welded pipe industry. It is a key process in the production of ERW steel pipe. The quality of high-frequency welding directly affects the overall strength, quality level and production speed of welded pipe products.Welding Seam Toughness Impact of ERW Steel PipeERW steel pipe welding process is the use of the skin effect of high frequency current generated by the principle of hot-rolled coil edge heated to a molten state, and then by mechanical extrusion welding method.

Welding Seam Toughness Impact of ERW Steel Pipe

Through this process of production of welded pipe fusion center will appear as a white line on both sides of the heat affected zone will produce fusion line extending from the middle toward the surface and the inner and outer metal flow lines. Since ERW steel pipe is used as the base material using welding materials, so its properties of the weld and base metal properties have What is Common Defects for Welded Steel PipesCommon defects for welded steel pipe. We will take a look at some common defects that occur on welded steel pipes and they are explained below 1. Lack of fusion This is simply the poor adhesion of the weld bead to the base metal. A weld bead that doesnt begin at the weld grooves root is known to be incomplete penetration.

Carbon Steel Seamless Pipe Schedule 40 CS ERW and Welded

For instance, a welded pipe has a longitudinal seam that is absent in a Carbon Steel Seamless Pipe. The presence of a seam could be problematic in some instances. For example, in the presence of high pressure, there could be chances of a welded seam failing and if not properly welded, it could get corroded on the seam area.Difference Between Seamless And Erw PipeIn a welded pipe, the seam or the weld-joint is the weaker part of the pipe limiting the strength of the pipe to the strength of the weld-joint. Generally, the process of supplying weld pipe begins with the rolling of a steel coil to the desired gauge thickness to form a flat strip.

Difference between Seamless & ERW Stainless Steel pipe

Nov 24, 2014Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.Differences Between ERW Steel Pipe and HFW Steel Pipe What is a Welded Steel Pipe About Welded or ERW SteelMay 16, 2018ERW is the general designation of resistance welded steel pipes. It can be sorted into two types alternated current welding (AC) and direct current welding (DC). According to different frequencies, AC welding can be divided into low-frequency welding, intermediate frequency welding, ultra frequency welding, and high-frequency welding.
