AIR LIQUIDE CB MATIC SM 42X43 column and boom

AIR LIQUIDE CB MATIC SM 42X43 column and boom welding station was manufactured in 2016 in France by Air Liquide Welding – Oerlikon (now Lincoln Electric). The machine, designed for precision circumferential and longitudinal welding, is the perfect solution for companies specialising in the manufacture of, among others, steel structures, pipelines, tanks and wind turbine towers. The welding process is performed fully automatically by means of a welding heads system, which enables the welding of two welds simultaneously on tubes with a maximum diameter of 4000 mm and I-beams with maximum dimensions of 3000 x 800 mm. The use of this solution significantly reduces production time, while maintaining high precision and efficiency at the same time.

The CB MATIC SM 42X43 column boom welding system on offer has a tube welding head for submerged arc welding (SAW) with a range of safety systems, i.e. laser pointers, sensors and a vision system. It features a modular design and full integration with the wire feeder, flux management system and power source. The adjustment in many planes, programmed in the convenient control panel, allows the head to position perfectly on the weld spot. During machining, the head is guided automatically using an edge finder.

Each head is supplied with high-quality current, generated by a STARMATIC 1200i AC/DC welding source. The unit, based on inverter technology, is ideal for demanding welding applications requiring constant voltage, amperage and wire feed speed. It supports all the key characteristics, i.e. CV (constant voltage), CC (constant current) and CW (constant wire speed). In addition, DC+ and DC- as well as AC operation allows optimum results to be achieved when welding materials with different characteristics. All of this, together with the possibility of simple integration with other equipment, makes the welder the perfect solution for submerged arc welding (SAW).

All this is completed by the flux feed and extraction system, which is an essential element in automated welding processes. This system, connected to the tank, is responsible for recovering and reusing excess flux. In this way, the cleanliness of the station is ensured, while maintaining the highest weld quality at the same time.
