Magnetic Arc Control - Industrial Applications

Magnetic Arc Control is used in these industries:

• Tube and Pipe Mills
• Fuel Tanks & Pressure Vessels
• Military
• Multi-pass Pipe Welding
• Repetitive TIG or Plasma Manufacturing

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.

An MP-1 magnetic probe is used in conjunction with precision wire feed to create a wide weave patterned weld bead, which has equally deep penetration on both sides. The magnetic arc oscillator eliminated the need for a mechanical oscillator.
