• TIG Welding Aluminum with Alternating Current TIG Welding Aluminum with Alternating current Characteristics of TIG Welding Aluminum **with Alternating Current (AC) **Process The welding of aluminum by the gas tungsten-arc welding process using alternating current produces an oxide cleaning action. Argon shielding gas is used. Better results are obtained when welding aluminum with alternating current by using... Read more >>
  • TIG Welding Aluminum with Square Wave Alternating Current  TIG welding aluminum with square wave alternating current differs from conventional balanced wave TIG welding in the type of wave form used. With a square wave, the time of current flow in either direction is adjustable from 20 to 1. In square wave gas tungsten arc welding, there are the... Read more >>
  • TIG Welding Aluminum with Direct Current Straight Polarity (DCSP) Characteristic of TIG Welding Aluminum with direct current straight polarity This process, using helium and thoriated tungsten electrodes is advantageous for many automatic welding operations, especially in the welding of heavy sections. Since there is less tendency to heat the electrode, smaller electrodes can be used for a given welding... Read more >>
  • TIG Welding Aluminum TIG Welding Aluminum The TIG (Tungsten Inert Gas) arc welding process is used for welding the thinner sections of aluminum and aluminum alloys. There are several precautions that should be mentioned with respect to using this process. Alternating current is recommended for general-purpose work since it provides the half-cycle of...
