In a previous blog my colleague Koen van Bindsbergen and I explained how we were able to achieve superior welds in the assembling process of our Bronkhorst hygienic flow meters making them suitable for food and sanitary applications. In this blog, I want to highlight a completely different viewpoint to welding: how can gas flow meters and pressure controllers be applied to optimise your welding process?
Most of these welding processes utilise gas to protect welds from oxidation and to ignite and maintain the welding arc. Manufacturers of welding equipment can capitalise on some of our flow meters’ features. Accurate flow and pressure control of shield- and backing gases used during your welding process will provide a constant and stable weld and thereby improve the quality of the welds.
After welding, the colour of a weld is an indication of its quality. The lighter the colours, the better the quality of the weld, with no discolouration being the best. Orbital welding, for instance, often produces very high-quality welds since processing occurs in chambers filled up with inert gas. For austenitic stainless steels and nickel-based alloys, the most used gases are argon, mixtures of argon and helium and even a mixture of argon with hydrogen. This latter one is particularly interesting as its reducing properties binds oxygen from the weld. An additional advantage is that less energy is required to complete the weld.
Flow instruments are used to provide a constant and stable gas mixture resulting in an excellent welding quality with hardly any discolouration. Bronkhorst flow meters and pressure controllers can help with creating the right mixtures, at the right time with astonishing accuracy.
Flow instruments can help the mechanised or robotised welding processes in three distinct ways:
Ultrasonic flow meters for the food industry need to comply to high-quality industry standards like 3-A for hygienic design. One of the requirements is hygienic welds.
