Perfect Welding

High-quality weld seams are a key criterion for many users of TIG welding processes. But in production environments which are constantly being streamlined to achieve maximum efficiency, time also plays an important role. With ArcTig, Fronius has developed a new TIG welding process for mechanized applications, which enables unprecedented speeds. The science behind ArcTig The newly developed ArcTig welding process builds on the foundations of traditional TIG welding. Yet in contrast to conventional TIG applications, the ArcTig welding torch…

What Is … Aluminum Welding with Alternating Current (AC)?

Posted on 4. July 2018

Welders carrying out TIG aluminum welding

We all know that AC/DC isn’t just the name of a hard rock band, but that it also stands for alternating current (AC) and direct current (DC). But what is alternating current really all about? What does it have to do with aluminum? What are half-waves in this context? And what is a “cap”? AC Welding Whenever aluminum is welded using the tungsten inert gas welding process, alternating current is used. Why? Welding aluminum is particularly difficult because the material…

Synchronized TIG Welding – Two Welders Working in Sync Saves Time

Posted on 6. June 2018

While TIG Welding is certainly a demanding process, requiring a high level of manual dexterity, synchronized TIG welding is on another level entirely. It requires a perfectly coordinated team that not only performs the same movements but also works together in synergy. This means that any process fluctuations caused by a welder on one side must be immediately compensated for by their colleague on the opposite side, either independently or when prompted to do so. The welders communicate via radio…

TIG arc between tungsten electrode and workpiece

What does “TIG” stand for? Why is inert gas used in this process? And what role do tungsten electrodes play? Welding is complex but the basics are actually pretty easy to understand. The Fronius “What is …?” series helps to build an understanding of welding and to maintain an overview of the basic terms. Tungsten Inert Gas Welding TIG welding is a process that enables top-quality weld seams. The arc burns between a temperature-resistant, non-melting tungsten electrode, and the workpiece.…

Automatic Welding Helmets for Safe, Efficient and Comfortable Working

Posted on 2. May 2018

Occupational safety/worker protection is the result of all measures and activities aimed at safeguarding the life and health of employees when carrying out their professional duties. This ranges from personal protection to health measures (e.g. noise or psychological stress) through to protective equipment, such as welding helmets. The key task for protective welding equipment is to protect the eyes and skin from glare and burns, and to protect the respiratory organs from harmful particles, dust, and vapors. Protection against Optical…

TIG Welding: Top-Quality Connections

Posted on 11. April 2018

Anyone wanting to carry out TIG welding will have to master their craft. While the welder guides the welding torch with one hand, they simultaneously add filler metal with the other hand. This not only requires a measure of coordination, but also a steady hand. The result is a spatter-free and smooth weld seam. Due to the high quality of the weld seams it produces, the tungsten inert gas welding process is used whenever the weld seam quality is of…

The importance of calibration for welding machines

Posted on 28. March 2018

If you want to guarantee that the quality of your welding equipment is up to scratch in the long term, you’ll need to calibrate them on a regular basis. For companies working with welding technology, it is essential that systems deliver consistent welding results without fail throughout their service life. The process of calibrating welding systems involves them being connected up to a calibration station to have their voltage, amperage, and wire feed speed measured. It is also an option…

Further development of power sources paves the way for digital business models

Posted on 18. December 2017

Digitisation and interconnectivity in industrial production is one of the most important topics of our time. Digitisation has become indispensable in our private lives. Social networks and online shopping are integral parts of our day to day lives. Now it is simply a matter of applying the benefits of interconnectivity to industry, for example by developing digital business models. In order for this to succeed, we must consider production processes holistically – it is no longer enough to identify and…

Industry 4.0 and welding technology

Posted on 19. September 2017

Interconnectivity, automation and digitalisation are questions that have to be tackled today in order to be a leader of tomorrow – and the welding technology sector is no exception. Thanks to the Internet of Things, welding is a high-tech process that is equally as sensitive to the influence of processors, control systems and software as it is to welding torches, electrodes or shielding gas. Smart factories as the product of the fourth industrial revolution Digitisation, automation and networking are the…
