Keyhole welding – definition and variants

Stichlochschweißen in PC Position

From the food industry through to the aerospace sector, wherever top-quality even weld seams are required, many companies rely on TIG welding. This process could be compared with a premium limousine: high class but lacking somewhat in terms of speed. And this precise problem can also quickly become a problem in production processes that use TIG welding technology: the TIG process can be inefficient due to its low speed, particularly for thicker materials that require multiple passes. But there is…

What is an arc and how does arc welding work?

A bright, bluish light. Everything’s fizzing and crackling. You can feel the tension in the air. This is what springs to most people’s minds when they hear the word “arc”. Lightning is an arc that you might see during a thunderstorm. On the railroad as well, an arc sometimes forms briefly between the catenary and the pantograph. Welders use an arc in a targeted way to join metals. But what precisely is going on? Lightning Railroad arc What is an…

MIG/MAG pulse welding – why do we use it?

Advantages and disadvantages of the pulsed arc compared to the standard arc Cruising along at high speed on the freeway – in a modern sedan, you feel as if you are simply gliding along rather than putting up a fight against the centrifugal forces. It mirrors the lightness of being, and enables greater distances to be covered with ease. But what would it be like if these driving dynamics and lightness were transferred to country roads or even urban traffic?…

Welding and Its Various Challenges in Shipbuilding – A Customer Story

Welding in shipbuilding – a Herculean task. The Gulet shipyard in Croatia primarily builds cruise ships in the form of large yachts, so is well placed to report extensively on the extreme welding challenges faced in the industry: limited space requires great skill and reliable selection of the suitable welding position. Welding while lying down or kneeling are par for the course here. The rugged, rocky Adriatic coast of Croatia spans 6000 kilometers. Set against the backdrop of turquoise waters…

Clean and hygienic: TIG welding in the food and drinks industry

Technological equipment in the dairy plant, ©Shchipkova Elena

Be it in the brewing trade or in cheesemaking, extremely strict legal requirements apply in the food and drinks industry. One hundred percent compliance with hygiene regulations is therefore of the utmost importance. In order to prevent germs and bacteria from taking up residence, welded joints must be as smooth as possible and, above all, non-porous. This is why the food and drinks industry relies on stainless steel, which is of course distinguished by its corrosion resistance and the fact…

How do I correctly apply the welder settings?

Schweißgerät einstellen

When is the user actually ready for welding? When they’ve prepared the workpiece, put on their gloves and helmet, the system is switched on, and the gas hose is already connected? What’s next? Our blog article provides answers using the example of MIG/MAG manual welding. 1) The parent material Long before it becomes a question of how the welder settings need to be applied, it is necessary to identify the metal the workpiece is made of – the basis for…

Assistance systems for robotic welding

WireSense

Driver assistance systems in cars and robotic welding in industrial production – are there any similarities here? If we look at the development stages of the motor vehicle first, it was initially analog systems such as power steering that made driving so much easier. Over time, more and more digital helpers in the field of passive safety were added, for example ABS, ESP, lane departure warning systems, and many more. Today the age of the self-driving car is almost upon…

MIG/MAG welding torches: special versions and wearing parts

Absaugbrenner

In the second part of our series on MIG/MAG welding torches, we take a closer look at special versions. The choice of MIG/MAG welding torches in particular is almost unlimited, with a version for every process variant, welding challenge, and personal welder preference. High-tech welding torch The more specialized and complex the application and welding process, the more high-tech the welding torch solution. The push-pull welding torch: In addition to the wirefeeder in the power source that pushes the wire,…

MIG/MAG Welding Torches: Making the Right Choice

MIG/MAG Brenner

Gas metal arc welding falls broadly into two categories: Metal Inert Gas (MIG) welding and Metal Active Gas (MAG) welding. Within these two groups, the market offers endless choice, with a host of solutions for different processes and control options. Yet the design of the welding torches is almost identical, with only a few small internal differences depending on the process in question. So what exactly is a “welding torch” and a “MIG/MAG welding torch” in particular? Read on to…

TIG Torches: What are the Differences and Which Torch does What?

WIG Brenner Varianten

If you google for TIG welding torches, one thing soon becomes clear: There’s an almost infinite choice. From the torch bodies, through all the various types of TIG gas nozzle, to the wide range of handles. But what exactly are the differences between all these TIG torches, and what does each one do? Which Torch Body is Suitable for What? The main thing is to hit the spot – that’s what it’s all about. Because even the most comfortable and…
