Tanks for milk & beverage transportation
Tank trailers are, among others, used for economic transportation of milk, water or other beverages. The tank may consists of several ring segments or is made by only one ring. The material therefore often used - depending on regulations by the authorities - are aluminium or stainless steel. Sheets of this material are joint together by Plasma Keyhole Welding or eventually Plasma Seam Welding.
The Plasma Keyhole Welding plays the advantage that wether filler wire, nor a joint preperation is needed, making the whole process economic and competeable to other joining processes.
