Fusion Butt Welding

Arc Machines’ extensive line of automatic orbital fusion (GTAW, TIG) tube welding systems addresses the needs and outperforms the welding specifications of industries as diverse as food, dairy, bio/pharmaceutical, aerospace, semiconductor, power generation and ship building, just to name a few. Tube or pipe sizes from 3/32” OD (2,3 mm) through 7.5” OD (190,5 mm) in wall thicknesses up to 0.160” (4 mm) can be welded x-ray clear, with 100% penetration.  Our liquid-cooled weld heads are ideal for OEM jobs, high production usage or heavy-wall applications. Our extensive line of weld head and power supply accessories increases production rates, results in weld heads that are more adaptable to multiple applications, and makes difficult welds easy. Whether it’s an ultra-high purity process gas line, a titanium fuel line, a high pressure hydraulic, or steam line, Arc Machines orbital welding systems are unsurpassed in their ability to repeatably produce critical welds at the touch of a button.
