New employees are first introduced to TIG welding in a basic training lasting several months. Only then are the first products manufactured for customers, whereby the following topics are handled in a multi-year development process, which includes the welding test for the tube welder CrNi relatively early: Material requisition Additional materials Gas protection Interpass temperature and welding temperature Maximum material temperature during welding Cleaning the weld seam Welding distortion Mechanical seam load

The pressure regulator can be tightened by hand without the need for a spanner. It reduces the stored bottle pressure from max. 200bar (on request 300bar) to an outlet pressure which is adjusted at the flowmeter. The flowmeters are used to set the required flow in l/min. Important: The pressure regulator has a constant outlet pressure of 2.5bar which is necessary to protect the gas flow sensor of the orbital unit. Versions: — Special Argon Pressure Regulator with twin flowmeter, brass — Special Pressure Regulator with twin flowmeter for H2-gases, brass — Special Argon Pressure Regulator with triple flowmeter, brass Pressure regulators with different connections and for use with other gas types or nickel-plated version available on request.

VSG systems offer a poven and economic solution for the inductive melting of metals or alloys under vacuum or protective gas atmosphere and subsequent casting. Applications: The VSG furnaces can be universally employed for melting and casting under high vacuum or different gas atmospheres in the laboratory or production, e.g. alloying, degassing, purification melting, re-melting processing of noble metals highly pure, highly alloyed steel. • Processing of: ◦noble metals ◦ processing of highly pure, highly alloyed steel ◦ High temperature resistant materials on Fe- Ni- Co- basis ◦ Solar-silicon and other special material ◦ Special- / super alloys
