The solid-state weld process uses less heat input because high-frequency (150-400 kHz) electromagnetic energy is used in conjunction with high pressure to join two materials. The material isjoined under heat and pressure instead of melted together with a filler material. Controlling key welding process parameters, such as frSee more on thefabricator h f erw welding steel pipe in stockHigh Frequency Welding(HFW) - Welded Steel Pipe, High Frequency Welding.

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.

Differences between ERW Steel Pipe and HFW Steel Pipe

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.Differences Between ERW and HFW Steel PipeHigh frequency welding (HFW) is mainly used for ordinary or thin-walled steel pipes. It includes contact welding and induction welding. DC welding is usually used for small diameter steel pipes. Generally, HFW is one of ERW production methods, which uses high-frequency welding technology. Therefore, ERW steel pipe includes HFW steel pipe. Tips: ASTM A53 covers seamless and welded steel pipe Differences Between ERW Steel Pipe and HFW Steel Pipe h f erw welding steel pipe in stockMay 16, 2018 · High-frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHz.

Difference between Seamless & ERW Stainless Steel pipe

Electric 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.Dealing with Low-Frequency-Welded ERW-jfkWith the use of high-frequency current, the problem of contact resistance is virtually nonexistent. As a result, high-frequency-welded pipe tends to be relatively free of the bondline defects that were common in the low-frequency and d.c.-welded material. The performance of ERW materials has improved steadily with time as shown in Table 1.Common Defects of ERW Steel Pipe WeldingERW steel pipe is fed into the molding machine, deformed into a cylindrical tube through an induction loop or contact welding angle, the magnetic field around the induction coil current is induced by the edge of the strip, the strip edge due to its resistance generated thermal resistance is heated, the heated extruded strip edge forming roll extrusion welds.
