Polysoude has found the eye of the TIGer in its latest cladding technology and is proud to highlight its features and main fields of application.
In this system, Polysoude has built on the main principle of Hot Wire Technology, being the preheating of filler material to reduce the quantity of energy taken from the electrical arc required to melt the filler, assuring increased productivity of cladding speed and deposition rate.
In addition to the pre-heated filler wire, TIGer incorporates a unique system of two tungsten electrodes in tandem configuration. This allows the ignition of two electrical arcs which, by way of mutual attraction, combine to convey a single heat source with a lower arc pressure than in classic tandem configurations, yet it is capable of reaching much higher cladding speeds and deposition rates than the standard TIG/GMAW HW process.
The TIGer system allows for enhanced process applications in cladding, being ideally suited to horizontal and vertical cladding, both inside and outside components.
With cladding speeds and deposit rates capable of reaching 950 mm/min with a deposit rate from 2.7 to 5.8 kg/h, the system has had conclusive results from adherence checks on cladded layers, indisputable outcomes from intergranular corrosion tests and positive outcomes from chemical analysis.
