EFW welding is a process in which a metal is heated by one or more consumable electrodes and workpieces to heat the metal. The arc fully melts the metal and filling material, and no pressure is needed to make the metal parts full of work. All from the electrodes. The operation procedure is as follows:


According to the operation requirement of welding wire of welder, setting correct welding parameters can adopt manual or automatic input mode.
(2) Check correctly, start the welding machine, enter the welding process, when the welding time is over, the machine will automatically enter the cooling state.
When the pipeline is completely cooled, remove the welding machine.
(4) Cutting the pipe with a plastic pipe cutter or a cutting device with a fine saw, the end of which is perpendicular to the pipe shaft. Cut the inner edge of the hair with a knife, scrape the welding area on the side of the pipe or socket, and clean the welding area.
_Special fixture can be used to connect the parts to be fixed. The roundness of the pipe should not exceed 1.5% of the diameter of the pipe, or it should be corrected in the corresponding fixture. Pipeline and fittings should be suitable for clearance. Generally, it is appropriate to insert micro-power. Excessive or small clearance will affect the quality of the interface. Check the insertion depth, slide the socket fittings into the socket end and place them correctly.
