Welding Meaning. Most people have seen or are aware of welding. In the DCEN circuit the current moves from the electrode to the workpiece.
Manufacturing nearly any modern product involves joining various separate components. In the DCEN circuit the current moves from the electrode to the workpiece. In fusion welding a heat source generates sufficient heat to create and maintain a molten pool of metal of the required size.
Welding is a fabrication process whereby two or more parts are fused together by means of heat pressure or both forming a join as the parts cool.
However owing to its extensive use providing information about the type and size of the weld through symbols becomes essential. To join metals by applying heat sometimes with pressure and sometimes with an intermediate or filler metal having a high melting point. DCEN and DCEP in welding are two important current polarities. In the DCEN circuit the current moves from the electrode to the workpiece.
