The plasma cutting process starts when the high voltage of a pilot arc is struck between the nozzle and the cathode/electrode. This particular type of reduced energy electric arc partially ionises the section between the plasma torch and the piece to be cut.
The high heat energy produced by the arc and the very high kinetic energy of the Plasma gas melt the metal to be cut with excellent cutting precision and perfectly squared cut edge.
The melt is consequently expelled from the cutting area by means of the same kinetic energy produced by the flow.
Plasma Cutting also offers other advantages, such as the production of a reduced area of heat flow and considerable cutting speed. This type of “cold” cutting also guarantees the safety of personnel, avoiding burns caused by distraction.
Venturi Acciai has two, made in Italy, latest generation plasma cutting systems in addition to other high quality metal sheet cutting methods. One of the two systems has been replaced with a new system equipped with rotating head which, during the plasma cutting process, makes it possible to prepare the edges for the subsequent welding operations, with different incidence angles. The rotating head or bevelling head is an additional service we offer to our customers that assemble the product.
Venturi Acciai staff that works in the DRY Plasma Cutting department is fully qualified and trained and follows courses organised by the manufacturer of the machines. The machines are perfectly integrated in the production layout and they operate by means of programmes that are cyclically updated.
This department fully meets the health and safety requirements as regards the workers and the environment: the two plasma cutting systems are installed in a large area with suction systems.
This is an important aspect because the high melting temperature inevitably produces metal vapours; if for any reason some chemical components reach boiling point, beyond the melting point, this could cause significant damage in an unsuitable work area; this would also be the case with the inevitable use of high voltage electricity sources.
The Venturi Acciai Plasma Cutting department is therefore composed of two machines supported by high performance Hypertherm generators mounted on two adjoining work stations, each one 3 m wide and 30 m long for a considerable total length of 60 m. They are totally accessible from the lifting and handling systems of the metal sheets to be cut.
The maximum and most suitable thickness to cut is 60 mm, for a well defined shape and a cutting surface ready to be welded or ready for any other type of finishing process.
The cutting and bevelling equipment is controlled by personalised nesting programmes, calculated by our technical staff after the correct and controlled interpretation of the data provided by the customer.
We have invested in the installation and upgrading of these modern systems to satisfy customer requirements, and above all to optimise the pre-processing of high and very high quality metal sheets to which Venturi Acciai has always given priority.
It would not be productive to stock high quality metal sheets manufactured by the world’s best steelmakers, without installing the right tools to enhance and underline their different technical, geometrical and surface characteristics.
One of the points of excellence of Venturi Acciai is therefore the Plasma Cutting department which, upon receipt of an order to transform the sheets, readily demonstrates its full efficiency; this department also reflects the company’s commitment to the revival of our markets of reference.
