Germs and bacteria have no business being present in the food industry. For this reason, surfaces and welded joints must be as smooth and as flat as possible. Weld seams that come into contact with liquids must always be ground flush. In addition, container walls and pipes must not exhibit any spatter or temper coloration after welding. Industry and regional or international standards are authoritative.
WELDING PROCESSES FOR CONTAINER AND PIPELINE CONSTRUCTION
TIG and TIG-related welding processes comply with strict regulations and standards.
Due to the high quality requirements, only TIG and TIG-related welding processes such as ArcTig or Plasma are considered in pipeline and container construction. High-alloy steels such as CrNi, nickel-based alloys, titanium, copper, or duplex are the main materials encountered. In order to avoid temper coloration and associated corrosion at the root (also called pitting), forming is essential.
