Welding and Hygiene in the Food and Beverage Industry

The hygienic requirements of the food and beverage industry place high demands on the welds that hold tanks, pipes and vessels together.

The requirements for a high-quality weld and weld surface finish are paramount in the dairy and other food and beverage industries, as the consequences of poor surface and weld quality can be costly and dangerous.Process tank

Recent contamination scares in the dairy sector provide some examples of the consequence of not getting things right. In effect, every metre of weld inside a storage or process tank or vessel represents a risk to be managed. Fabricators must make significant efforts to ensure that both the weld integrity is adequate and that the surface finish meets the specified requirement for hygiene.

Automatic plasma arc welding (PAW)

Automated welding equipment produces higher quality welds with improved efficiency

PAW enables an excellent weld quality to be produced, with the introduction of minimal heat and with no removal of parent material required for weld preparation. Unlike the TIG process, which is susceptible to tungsten inclusions from the exposed electrode, PAW has no exposed electrode and, consequently, significantly reduced risk of inclusions.

Weld quality is evidenced by the superior radiography test performance that results from the PAW method. Butt welds up to 8 mm thickness can be completed in a single pass with only a gas backing shield required. Weld reinforcement is minimised and this assists in the subsequent surface treatment to obtain a smooth weld finish suitable for sanitary applications.

Automated systems not only reduce fabrication time and costs, but result in a consistently smooth and high-quality finish to weld seams that is integral to achieving a sanitary finish. The surface roughness of the internal weld seams is specified in ‘Ra’ — a measurable roughness, in micrometres, which is obtained using an Ra meter. Traditionally, surface roughness has been specified in ‘grit’, which is not practical in a sanitary application. Grit refers to how course the polishing medium is. The finished surface is not measurable in grit and may have a varied roughness when completed by different operators. This is not ideal when working within hygienic environments.
