In 1998, a new type of system control revolutionised conventional arc welding technology by using digital instead of analog signals. In the process, modern information technology (IT) made a successful entrance into the world of welding.

Since then, digital controls have penetrated all areas of processing and equipment control. This offered users previously unimaginable advantages and new perspectives. The platform concept from Fronius played a significant role here, as it represents the intelligent basis for different gas-shielded (MIG/MAG) welding methods.

The processes involved include short-arc welding, pulsed-arc welding and spray-arc welding, as well as CMT (Cold Metal Transfer) and TimeTwin. Digital systems are also available for welding with DC and AC current, tungsten inert gas (TIG) or the high-performance LaserHybrid method.

In accordance with the company's approach of developing solutions that meet the real needs of users, customers can order digital technology for all techniques and variants. Innovative solutions allow users, for example, to join thin sheets above 0.3 mm thick; to join aluminium to steel; and to braze or weld without any spatter. Users can rely on consistent a-dimensions and safe penetration to achieve pore-free results that display a high degree of fusion. Any number of welding systems can be interlinked, and all the processes can be managed from a PC environment that acts as a virtual control station.

Users also benefit from stable arcs, together with excellent droplet detachment, high deposition rates and high welding speeds with the associated low level of heat input.

So what exactly are the benefits of a platform concept?

Manufacturers supply mature component hardware that has been successfully tried and tested in a number of different systems and under varying conditions. The hardware is designed for modular use, which means that it can be used in different systems, reducing the diversity and quantity of replacement parts.

Examples of this include torches; hose packs; wire feeders; and cooling devices. In everyday use there are also a number of "soft" factors that are at least as important; identical surfaces and identical operating logic reduce training requirements, familiarisation time, and help to maximise flexibility.

One of the intrinsic advantages of the system is that its "intelligence" now lies in the software, rather than in the hardware. The software is inexpensive; almost freely interchangeable; and functions can be upgraded, allowing developments that are currently not even at the planning stage to be incorporated and implemented later on.

Accordingly, the second decade of digital welding technology will feature numerous further innovations, including more efficient and more simplified systems for standard processes.
