Model 52 Heavy Duty Precision Weld Head
4Pages

The widest range of orbital welding equipment in the world The Model 52 is engineered and designed for high-deposition circumferential and flat welding in heavy industrial and harsh field applications where quality requirements are stringent and the use of the GTAW process is beneficial. It is intended for all-position, automated welding of pipe, plate or fittings using the Cold or Hot Wire Feed GTAW (TIG) process. The Model 52 weld head provides all functions necessary for high-quality orbital pipe welding and other elements required for an automated pipe welding system, such as precision guide rings, and one of several AMI Power Supplies.

STANDARD FEATURES Synchronized torch oscillation. 4” (102 mm) arc and oscillator slides. Cross-seam steering. Exclusive, zero-backlash dual gear drive. Digital encoder feedback on all functions. Water-cooled main housing. Tool-less mounting mechanism. On-board wire feed mechanics, single or dual wire feed system. TORCH OPTIONS The M52 weld head provides a durable, extremely versatile, heavy-duty platform for using a variety of torch options: Single or dual wire entry torches. Narrow-Gap Torches up to 12” (305 mm) deep groove. Torches for remote welding with Vision. Hot or Cold Wire options....

Í2 HEAVY-DUTY PRECISION WEID HEAD The AMI NGT (Narrow-Gap Torches) were designed to perform narrow groove heavy-wall pipe and vessel welds, with less heat input and shorter weld times than conventional narrow gap equipment. These torches use a rotating tungsten, which provides mechanical manipulation of the arc and wire feed within the groove. The integral gas cup provides direct gas shielding of the tungsten and the weld melai. The rotating electrode assures excellent side wall fusion and minimizes weld defects. The rotating electrode in conjunction with the narrow preps, allows deposition...

OPTIONS The Model 52 weld head and torch are just two of the elements required for an automated pipe welding system. Precision guide rings providing positive, gear-driven traction, AMI’s Model 415 Power Supply, and many other options offer a complete system suitable for high-quality orbital pipe welding of a wide range of applications with excellent productivity. 10 or 40 IPM Travel (rotation) Motors: for applications requiring more torque or faster travel. 300 IPM Wire Feed Motor: for use with special-application torches. Oscillator Cross-Seam Stroke: 4” (102 mm) standard, range increases...
