Achieving high quality welds with an orbital power source

Welding with an orbital TIG power source allows you to achieve high quality welds. These high standards are a requirement in a large range of industrial fields, where regulations and standards don’t allow for welding mistakes.

These rules also require a the traceability of every single weld.

Welding without any defects by perfect programming


Remember, with orbital welding, the DMOS welding instructions and parameters have to be controlled by specialized companies or institutions. Afterwards, the welding programs will be saved by means of a USB stick, each USB stick has the capacity to save up to 200 programs.

You can use as many USB sticks as you like, but most companies work with less than 100 programs.

Proving the quality of the welds


By orbital welding, you will have very low reject rates. This can occur when the environmental conditions change or the tolerances of the tube differ compared to the programed parameters.

For some applications you do not need 100% control of the welds, but some high purity industries control every weld, due to the high stakes. For this reason, the traceability of a weld is extremely important.

All AXXAIR power sources are equipped with a data acquisition system, which enables the welder to control and verify the welding process, second by second, for all ranges of tube diameters.

Thanks to this equipment, the experienced welder can modify the program -whilst using the information transmitted by the data acquisition system. He will have to get a new control number for the modified program.

This type of equipment programming is often presented as an option by other manufacturers, but we integrate them as a standard in our TIG power sources because of the importance of traceability in:

  • the food- and pharmaceutical industry,
  • biochemical and nuclear applications,
  • as well as the manufacturing of semiconductors.


Orbital power sources and risk management


Existing legislation which is similar in almost every country, as are the different industrial applications. A perfect weld has to be smooth, without any cavities or cracks, presenting nearly the same physical characteristics as the basic material.

All necessary information has to be registered in a data acquisition system, which proves all welding parameters for every weld. As stakes can be extremely high – imagine the cooling tank of a nuclear reactor – the responsibility must be quickly identified if a problem occurs.

By using TIG welding and a data acquisition system you can confirm, at any moment, the conditions in which the welds were achieved.

And, of course, you can find new markets with orbital welding and data acquisition systems - quality has become a most important factor for your customers and so for you.

Every welding mistake costs money in terms of material, working time, amortization of the equipment and, of course, the image of the company. Obtaining high level quality, at the first step, is a major challenge.
