Steel Transfer Technology

High-tech for steel welders

High-productivity welding of steel puts a great deal of strain on both man and machine. To achieve the bestpossible working conditions in such a tough environment, the operating behaviour and user friendliness of the equipment have to meet the most stringent requirements. Factors like optimum functionality, energy efficiency, mobility and reliability also have a positive impact on the bottom line. With this in mind, Fronius developers devised a solution called Steel Transfer Technology.

The Digital Revolution changed the face of welding technology for ever. With the TransSteel product family, the Fronius developers have placed their know-how at the exclusive disposal of welding professionals working in mechanical engineering and structural steelwork, in the construction of pipelines, cranes, rail vehicles, tanks and vessels, and in shipyards and other steel-processing sectors. Where both the manpower and every part of the welding equipment used for joining heavy steel workpieces are stressed to the maximum, what counts above all else is system performance. “Man and machine must understand one another with eyes closed” was the developers’ declared aim. To achieve it, they uncompromisingly “went the whole way” with TransSteel: ease of operation and rugged reliability, plus perfect welding properties.

Uncompromisingly reliable

Steel Transfer Technology is a result of decades-long Fronius experience in both inverter technology and digital welding technology. The products of the TransSteel series stand out for their compact shape, low weight, minimal dimensions and elegant, functional styling. The central control and adjustment unit is linked to the digital signal processor and ensures that the desired target status is maintained throughout the entire process. This results in a process that is always precise and reliable and permits exactly reproducible welding results. For topquality joints between weldments made of “classic” and even galvanised steels, users can choose from remote-control, manual and robot welding options.

Ignition control for three types of arc

Perfect welding properties are the product of complex interrelationships between ignition, arc and burn-off behaviour. Steel Transfer Technology means that TransSteel comes fully loaded with expert knowledge, making this welding system the ideal equipment for its chosen field of use.

A key characteristic feature is its special ignition control. It prevents the nuisance of droplet-formation at welding startup. Three types of arc can be selected, in the form of characteristics: “Steel root”, with its fine, soft and stable arc is suitable for e.g. welding root passes and filling wider gaps. “Steel dynamic” is characterised by its concentratedly hard, dynamic yet stable spray arc, with which the welder can penetrate deep into the plate-metal parts to be solidly joined. The third option is the standard arc “Steel”. It can be used to cover a large part of the welding-range for steel. All the parameters needed for joining steel are easy for the welder to select, at the push of a button.

The whole: much more than the sum of its parts

All in all, operators profit from the system’s lower susceptibility to faults and from a minimised defect rate, and save on both time and costs. The strict focus on the requirements and needs of steel welders brings not just greater process reliability and ease of operation but also a cost advantage in terms of the capital outlay. Other beneficial aspects that are worth considering include the comprehensive warranty, which can be flexibly adapted as needed, and the benefits of having just one “communications interface” to a single system partner. Another aspect of the economic advantages is the environmental and social responsibility that they imply. For durability and long-term technological viability mean that careful use is being made of resources. The A-to-Z system performance of the TransSteel system also takes less of a toll on precious human resources like productive energy and quality of life.
