Electric Fusion Welding Pipe Process

Electrofusion is an electrical fusion process by which an external sleeve fitting incorporating an element is installed to poly pipe or fittings and with application of electrical current they are welded to each other.

Electric fusion welding pipe process.

Efw pipe vs ssaw pipe. Efw electric fusion welding steel pipe refers to an electron beam welding the use of high speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt the formation of the weld. Welding process employed is gtaw for root pass and saw tig for final pass with suitable filler wires as prescribed by aws specifications and asme. The weld of the high quality erw welded pipe can reach the same level of toughness as the base metal which cannot be achieved by the submerged arc welding process.

It is mainly used for welding dissimilar steel welding sheet or which high power density metal weldment can. Fusion welding is a process that uses heat to join or fuse two or more materials by heating them to melting point. The process may or may not require the use a filler material. Fusion welding is a generic term for welding processes that rely on melting to join materials of similar compositions and melting points.

Efw is the abbreviation of electric fusion welding. Efw steel pipe is formed by rolling plate and welding the seam. The efw pipe divison consists of a jco forming press helical spiral mill inside and outside welding system heat treatment furnace and testing facilities. Fusion welded method of new polyethylene pipe.

Electric fusion welding efw steel pipe refers to an electron beam welding the use of high speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt the formation of the weld. Electric fusion welding efw steel pipe refers to an electron beam welding the use of high speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt the formation of the weld. Due to the high temperature phase transitions inherent to these processes a heat affected zone is created in the material. The current applied to the fitting is regulated and supplied by an electrofusion welding machine which controls the amount of voltage amps and welding time supplied to a.
