THE digital TIME process from Fronius, represented in Australia by Smenco , opens up even greater potentials for increased productivity with a 30% higher deposition rate when welding thick steel plates.
The basis for this comparison is the TIME high-performance welding process that has been around since the 90s.
In addition to excellent profitability, the new TIME process from Fronius stands out due to the advantages provided by digital systems such as outstanding welding characteristics, the 100% reproducibility of all results, digital microprocessor control and a modular system concept.
Above all, they benefit users who wish to use manual high-performance welding for greater weld lengths and cross-sections.
Machine constructors, structural steel fabricators, constructors of building machines, cranes and ships are now able to achieve deposition rates of up to 11 kg/h at 40% duty cycle. High-performance welding starts at deposition rates of 8 kg/h.
According to definition this applies for solid wire electrodes of 1.2 mm diameter and wire feed speeds over 15 m/min.
With the new TIME 5000 Digital welding system a 15 to 25 mm stick-out supports the high-performance welding process. This length, which is greater by up to 15 mm compared with normal MAG (metal active gas) welding, means that the wire is heated up which, therefore, makes higher wire feed speeds and deposition rates possible.
The power source is correspondingly designed for 500 A at 75% duty cycle and 25 °C ambient temperature. A disc-type motor powers the 4-roll drive of its wire feed unit at feed rates of up to 30 m/min.
The type of shielding gas is specific for TIME welding. Depending on the process and boundary conditions, the experts at Fronius recommend 2-component gases based on Argon/CO2 or 3/4- component gas based on Argon/CO2/O2/Helium.
Here too the advantages of the digital technology are evident: the parameter sets for numerous shielding gas mixtures are stored and can easily be called up by way of the synergic function. This also applies to further process know-how.
There is a built-in 3- parameter control to prevent welding defects when starting and stopping. Thus the user can set desired values regardless of the main output or can adjust the length of the arc to suit. There are also general advantages for investors and users arising from Fronius’ modular system design.
Components such as the welding torches and wire feed unit are interchangeable with those of the digital equipment series. Even the applications are characterised by their flexibility.
Although the TIME process focuses on low-alloy, non-alloy or low temperature-resistant special steels, the user can nevertheless use the TIME 5000 Digital welding system to weld other materials such as aluminium or CrNi steels.
