Carbon Arc welding

The carbon-arc welding is the one type of arc welding. Where carbon or graphite are used as an electrode. There are two methods is used for produced an arcs, the single-carbon process and another is the twin-carbon process. The main difference is, the twin-carbon arc welding carried electrically independent torch. The carbon-arc welding is invariably carried out with direct current. The heat is produced between carbon electrode and work piece, base metal melts with this heat and additional filler metal can be added where extra metal disposition is needed. The essential point of this carbon-arc welding is that the filler rod quite difference from the ordinary filler rod. Because it can not be connected with current source.
