As the name implies, the heat generated by the weld power is a result of the material's resistance to the flow of electrical current. The pressure comes from rolls that squeeze the tube into its finished shape. The two main types of ERW are high-frequency (HF) and rotary contact wheel.

How to Identify Seamless or ERW Stainless Steel pipes? To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the pipe. If it is ASTM A53, Type S means seamless. Type F is furnace but welded, Type E is Electrical resist welded. Thats how. It is the easiest way to identify wether pipe is seamless or ERW.

Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, because the manufacturing process is fast, it is ideal for large production runs of small (<= 24 in.) diameter sections.
