Welding technology

Automated orbital welding carriage The Gullco Pipe KAT ® is an automated orbital welding carriage designed for pipe welding applications. Suitable for field pipeline manufacturing and power

plant construction, the Pipe KAT is a fully integrated welding system that includes a remote control pendant to allow adjustment of critical application parameters during the welding process, including oscillation width, speed, dwells, wire feed speed and voltage adjustment. The carriage operates on a track band made of durable aluminium extrusion by engaging the track with self-aligning wheels and a rack and pinion drive. This wheel assembly uses a lever to engage the track, making it quick and simple to install the carriage. Gullco International Ltd – Canada

Workshop welding machine The Alfa 400 Easy Life workshop welding machine is designed to fabricate fittings by joining pipe segments with the help of special jaws. crosses and wyes from 90 to 315mm (4" to 12" IPS).

The built-in memory allows the machine to store 4,000 welding cycles (including the set diameters and SDR). The welding data can be transferred to a PC through a serial port (a USB adaptor connector is available) and data management software, and a printer can be connected to the serial port to obtain a welding report at the end of each welding cycle. The heating plate features a new, automatically operated horizontal sliding system that enables fast side- sliding of the plate during the exchange period. The milling cutter, for levelling the ends of pipes and/or fittings, slides on recirculating ball slideways, with an electronic device for a soft start. The machine, which is available in 230V and 400V versions, also features an upper cylinder, to be positioned on the jaws, for welding extra-thick pipes or for when it is necessary to use high pressures.

It is composed of a machine body with two carriages, one of which is driven by a hydraulic system; and a control panel that features the Easy Life system, which allows a complete welding cycle to be carried out in a simple, intuitive and repeatable way, reducing operator involvement to a minimum.

It can also weld special and moulded fittings such as elbows, tees and flange necks, with the use of different jaws. The machine can handle elbows from 90 to 400mm (4" to 16" IPS), and tees,
