Purging

Measuring devices are another key factor in orbital welding. Our oxygen analysers and purge pressure analysers can measure and document the residual oxygen content in ppm (parts per million, during welding < 30 ppm = 0.0030 %) and the purge gas pressure inside the tube before and during welding.

As a one-stop supplier for orbital welding systems, we also offer purge bungs and other accessories for optimum alignment of all parts and tools.

Before welding, the oxygen level inside the tube is crucial. The Oxy EVO and Oxy Smart measuring devices provide precise and reliable results.

Purging

Proper purging is absolutely essential to guarantee high-quality welding of high-alloyed, corrosion-resistant components. Our Oxy EVO oxygen analyser can be connected to our orbital welding controllers for the purpose of inspecting and documenting the residual oxygen content and evaluated. You are free to choose the value in ppm entered in the controller.

Unless specified otherwise, a value < 30 ppm is generally sufficient for starting welding. The controller will not allow welding to commence until the measured value drops below the entered value. The equipment is calibrated so that it measures with an accuracy of +/- 2 ppm in the welding-related area below 30 ppm in the case of inert gases.

Analysers that display values as percentages are not recommended ➝ 0.1% = 1,000 ppm!
