high frequency welded steel pipe erw Description

What are the requirements for a pipeline welder?What are the requirements for a pipeline welder?The qualifications you need to become a pipeline welder vary by state and employer. In general, you need a high school diploma or G.E.D. certificate as well as experience working with various tools and welding equipment.Reference ziprecruiter/e/How-to-Become-a-Pipeline-Welder How does RF welding work?How does RF welding work?Radio Frequency (RF) welding is a process that uses electromagnetic energy to bond materials. Also known as High Frequency (HF) welding, this process creates an oscillating electric field that shifts and moves polar molecules within the materials between a tool and the platen. The movement of these molecules releases energy in heat form.Reference jtemachines/how-does-rf-welding-work/ 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.
