Innovative orbital welding process THE choice to automate the welding process occurs for various reasons – technical, organisational and economical. Many agree that this is the ideal technique for obtaining clean and smooth welds.

the most difficult welds with ease. The SAXX suggests the control of the gas of the torch or weld head, but also of the internal shielding gas of the tubes. The gas flows are, for the first time, displayed digitally and are recordable. The system controls and records welding data every second. This data is stored on a USB stick and can be transferred to DMOS/ QMOS records via the ‘Weldreport’ software. It also allows the management of the residual ppm inside the tubes to guarantee a level of colouring of the interior of the weld. The measurement of ppm is carried out by connecting the SPPM-10 from Axxair to the SAXX. The software HMI as well as the general software can be updated by USB key. One USB stick can store up to 200 welding programs.

High-end industrial sectors like the aerospace industry, high-speed trains, nuclear or biotechnology lean towards it for obvious reasons of precision and dependability. In other areas, like in the pharmaceutical and chemical industries and in agribusiness, smooth welds are indispensable so as to avoid all risk of contamination or the possibility of corrosion in the area of the weld. Automated orbital welding involves rotating continuously at 360 o in an arc around a cylindrical shaped form. This is the best technical means to get clean welds, with uniform precision particularly for small diameters of thin widths. It allows for thrust control of the process with the help of the programming of the welding settings. To ensure work without irregularities, both on the inside and the

outside of the tubes, it is advisable to choose automation for smooth welds. Axxair has launched its latest generation of orbital welding power sources – a new technology to simplify the orbital welding process for applications in industries working with thin walled stainless steel tubes. The easy-to-use product is endowed with an extensive range of possibilities. Users have access to sophisticated functions allowing them to perform
