With vacuum technology and computer applications, material titanium VAR method soon became titanium mature industrial production technology, and today the vast majority of titanium and its alloys ingots produced using this method. VAR method notable feature is the low power consumption, high melting rate and good quality reproducibility, VAR ingot smelting method has a good crystal structure and uniform chemical composition. Typically, finished ingot obtained by melting VAR method. Remelted at least twice. VAR method using titanium ingot production, process manufacturers around the world use similar, the difference lies in the use of different electrode preparation methods and equipment. Preparation of electrodes can be divided into three categories, one with the overall electrode feed continuous suppression medical titanium alloy of press parts, excluding the electrode welding processes: two monolithic electrode pressed into a consumable electrode welding. And by plasma welding or welding into one vacuum; the third is prepared using other casting melting electrodes.
