    • Why HF Erw?
    • Welded Beam Customization
    • HF Erw Enables Lean Manufacturing
    • Applications
    • Weld Quality. Solid-state, high-frequency welding for ESS in general requires minimal heat input, produces a narrow heat-affected zone (HAZ), and results in improved weld properties. 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...

  7. high frequency electrical resistance welding square steel pipe Electric resistance welding - Wikipedia

    Low-frequency Electric resistance welding. Low-frequency electric resistance welding, LF-ERW, is an obsolete method of welding seams in oil and gas pipelines. It was phased out in the 1970s but as of 2015 some pipelines built with this method remained in service. Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape.

  9. high frequency electrical resistance welding square steel pipe Introduction to Welded Pipe Manufacturing - The Process …

    High Frequency Welding; Rotary Contact Wheel Welding. High Frequency Welding. Initially ERW manufacturing process used low frequency A.C. current to heat the edges. This low frequency process was used from the 1920’s until 1970. In 1970, the low frequency process was superseded by a high frequency ERW process which produced a higher quality weld.

  10. high frequency electrical resistance welding square steel pipe 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.
