Stainless Tube Mill
Using two MA-40 magnetic arc controls, two MP-4 probes, and an AVC-5 system,
the TIG arc is compressed and oscillated to reduce arc drag
and porosity. Increased penetration, consistent seam fusion
and very high travel speeds were achieved using the first
arc for preheating (oscillating the arc longitudinally) and
the second arc for compressing the arc for full penetration
welding. |
