Narrow Groove welding - Orbital welder
Orbital welding equipment to weld regular and multilayer high-chromium steel for power generation boilers, stainless steel for nuclear power generation equipment, Inconel® alloy and other high-alloy steels, and thick-wall stationary pipes. This process allows uniform welding with first-layer penetration in all positions. The wire feed and base metal fusion rates can be controlled independently, allowing the operator to select from a range of welding parameters.

Inside Diameter Welding
Special Inside Diameter (ID) orbital welding heads for cladding or welding from the inside diameter of pipes. Sophisticated heavy duty weld heads with AVC, Oscillator, and tilt functions that can be used with a wide variety of AMI torches and video monitoring systems. The weld heads are water cooled and are designed to allow easy set-up and operation. ID weld heads are often used for narrow gap welding of heavy wall pipes and cladding of pipes. Cladding heads are fully integrated and can be equipped with custom torch configurations.

Fusion Welding
AMI manufactures and sells the most extensive line of automatic orbital welding systems in the world. Our fusion tube and thin-wall pipe welding systems are designed to meet or exceed the critical welding specifications of industries as diverse as aerospace, bio-pharmaceutical, semiconductor, nuclear, food/dairy/beverage, and other industries and applications requiring high-quality sound and sanitary repetitive welds with 100% penetration.

Tube to Tube-sheet Welding
Tube to Tubesheet weld heads for autogenous or with filler wire welding.
Weld heads can be configured with a wide selection of torches and configurations to match all common tube sheet design. AVC function is standard on the more complex heads. AMI’s proven tube sheet weld heads provide productivity and ease of operation for our customers. Quick set-up, precision, and durability make the AMI weld heads the tube sheet manufacturers’ first choice

Integrated Welding Systems
Non-orbital, or fixed-head, automated welding systems for welding or cladding. A wide selection of AVC and Oscillator slides that can be configured to match the needs of the application. Turn-key welding packages include AVC, oscillator, wire feeder, power supply and touch screen controller. The weld heads can be easily integrated with the client’s existing positioners, manipulators, or other fixtures. On request, AMI can supply a welding system that includes the welding fixture or the positioning equipment

Thanks to its ability to realise high purity results, orbital welding found its place in the production of clean-room components for the semiconductor industry. Its application has now expanded to the construction of pipework and equipment for diverse industries like food processing, pharmaceuticals, chemical engineering, automotive engineering, biotechnology, shipbuilding and aerospace. Automated orbital TIG welding is also used in the construction of power stations, (thermal power plants). The construction materials used must be able to withstand the enormous mechanical loads produced by the high pressures and temperatures created by the media carried in the tubes. Notches, pores and inclusions in the weld seams must be avoided at all costs, as these create weak points that can lead to subsequent formation of cracks, which in turn can have serious consequences in terms of component failure. This means that tubes are often made from nickel-based materials with walls up to 200mm thick. One manufacturer has developed an orbital narrow gap welding system with hot-wire feed specifically for this purpose, which uses running gear that moves on a guide ring fixed around the tube. This new variant has excited a lot of interest in the sector, with the worldwide boom in power station construction fueling the never-ending search for increasingly productive manufacturing methods using new types of high-temperature steels.
