Stainless Tube Mill
Using three AVC-5 arc length control systems, two MA-40 magnetic arc pattern controls and two MP-4 probes,
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. |

AVC
with Seam Tracking
This system utilizes several components
to track the edge of a large-diameter pipe. A magnetic oscillator
and TIG wire feed system work together with an AVC for high-deposition
multi-pass welding. A seam tracking system compensates for side-to-side
irregularities. |

Tube-to-Fitting Stainless Steel
The AVC system enables a two-pass weld
consisting of a precise, low-voltage fusion root and then
a second fill pass and cap at a higher amperage and voltage.
Magnetic oscillation and wire feed were used only on the second
pass. |
