Fielding a competitive race car requires tires engineered specifically for the vehicle, track and course condition. Unfortunately, too many fabricators using orbital GTAW systems slap on the equivalent of discount, all-season tires when they use generic tungsten electrodes.
Making the right choice will create the possibility to optimize results. A proper orbital GTAW process requires a tungsten electrode system that focuses on geometry, surface roughness, shielding gas choice and other factors that influence arc starts, arc stability, total heat input, and bead characteristics. Aligning all of these factors leads to working cycles longer than compared to generic electrodes. That’s why AMI is the only brand on the market that offers a permanent solution.
