50+ Dc Tig Welding Aluminum Pics. This post may contain links that will earn us a commission at no cost to you. Thick aluminum parts where distortion limitations are tight, large aluminum parts that would otherwise need to be preheated, tack welding thick aluminum to prevent cracking of tack welds.
DC TIG Welding Aluminum With Argon and Flux from hildstrom.com Dcen should provide good penetration. The short of it is that dc is appropriate for welding steel and iron, but ac is what you need to weld aluminum. When tig welding aluminum, alternating current (or ac) is almost always used.
Aluminum also has a tenacious oxide film on the surface and when ac switches to electrode positive, it helps to remove the oxide and clean the surface.
Welding some aluminum on dc with stick electrodes with decent results. Waveform control, high frequency starts and arc balance provide optimal tig performance for welding aluminum. So some applications for tig welding aluminum using dc are: Tig welding aluminum since ac supports welding at a higher temperature.
