Automated metal removal system facilitates uniform U or J grooves in weld joint preparation

The Arcair-Matic® N6000 metal removal system from Thermadyne® Industries is designed for automated gouging of steels and other metals with the air carbon arc process.

The system is suited for metal fabrication, particularly for preparing uniform U or J grooves in weld joint preparation. Groove depth is maintained with a tolerance of ± 0.025 in. The system also is used for backgouging of seams and for removing defective welds and cracks.

The system measures minute variations in the arc voltage or amperage, compares them with present standards, and takes immediate action through its feedback control, maintaining the precise arc gap for optimum gouging, according to the manufacturer.
