What is Electric Fusion Welding (EFW) and Electric

Electric fusion welding is the combination of metal and metal by heating one or several consumable electrodes and the workpiece.Electric resistance welding is a welding process that uses a strong current to pass through the contact point between the electrode and the workpiece to generate heat from the contact resistance.The arc of electric fusion welding melts the metal and the filling What is Electric Fusion Welding (EFW) and Electric Electric fusion welding (EFW)is the combination of metal and metal by heating one or several consumable electrodes and the workpiece.Resistance welding is a welding process that uses a strong current to pass through the contact point between the electrode and the workpiece to generate heat from the contact resistance.What is EFW steel pipe - pipelinedubaiStandard of EFW steel pipe ASTM A672 API 5L,ASTM A53 B,ASTM A178,ASTM A500/501,ASTM A691,ASTM A252,ASTM A672,EN 10217.ASTM A672 standard specification for electric fusion welded steel pipe for high pressure service at moderate temperatures.This specification covers electrical-fusion-welded steel pipe for high-pressure service at moderate temperatures.
