Automatic GTAW Tank Welder with Laser Seam Tracking

CHALLENGE

This Good Customer had multiple hand welders making circumferential seam welds on a wide range of Pressure Vessel Round Tanks for the Aerospace Industry.

The Weld Quality required Full Penetration with positive weld bead reinforcement on both the O.D. & I.D. along with 100% X-Ray clear inspection and a clean Dye Penetrant inspection.

The hand welders needed to be very skilled, and the weld times and purge times were very long with no gas purity validation, tank orders were running very late, and they needed a low skill highly productive weld cell to get caught up with late orders.

SOLUTION

Weldlogic Engineers & Weld Specialists selected our AWS- Advanced Weld System controller to manage the entire cell to insure repeatability of 1% or better.

The system included a 400 Ampere D.C. power supply, Arc Voltage Control, A.C. Servo Driven Wire Feeder, A.C. Servo Driven Dual Spindle Lathe.

Quick Purge to evacuate the tank to less than 100 P.P.M in 2 minutes, 2-D laser Seam Tracker to track over weld seam, and custom software to fit the customers requirements.

Resulting in a High Quality , High Production X-Ray clear , family of pressure vessels automatically welded to the highest standards to enable the customer to meet delivery requirements.
