Polysoude presents its innovative, customer-focused solutions with its mechanised and automated TIG welding technology – a technology that has the power to weld tube, pipe and tube sheet applications, capable of withstanding severe mechanical stress, absorbing high dynamic loads and providing corrosion resistance.

TIG welding offers the flexibility of welding with or without filler wire. Using mechanised or automated TIG welding equipment, any desired number of welds can be produced with sustained reproducibility and with each individual joint exceeding the requirements of the strictest production objectives – the ‘Zero Risk/Zero Defects’ approach.

Polysoude orbital TIG Zero riskManual welding is not required, as operators take over by running the auto- mated TIG welding equipment. Results, therefore, are excellent, sustainable and quality is predetermined.

Pre-programming

Before mechanised or automated TIG welding takes place, the particular procedure and all related parameters are developed and approved customer-specific welding sequences and instructions are stored and transferred to the designated welding equipment by means of a PC or a USB flash drive – and this can be done in the workshop or on site.

Moreover, in the case of the most sophisticated equipment, such as Polysoude’s P6 welding system, programming is even further developed. This technology incorporates a touchpad, which has an easy-to-understand, intuitive graphical user interface (GUI). The virtual synoptic of the GUI (Figure 2) is presented on the touchscreen, not only allowing for complete weld data management, but also offering numerous auxiliary functions to support the development and finish of any TIG welding sequence.

The operator must ensure that the work-pieces are correctly positioned. However, after the welding cycle has started, the equipment is completely controlled and monitored by the uniquely designed power source, which initiates and controls all functions and movements of the power source and the welding head.

The TIG welding cycle begins with- out the addition of filler wire. Wire feeding speeds and pulsed wire feeding are programmed and managed by the power source. The welding current starts with a relatively low intensity, and without any movement between the electrode and the work piece, a pool of molten metal forms. Only then, is the current raised to the programmed final level, the movement of the torch or the rotation of the work piece starts and the filler wire is added.
