What exactly is … gas shielded arc welding?

iWave

Gas is invisible, sometimes odourless, sometimes not, but always explosive and dangerous. Isn’t it? Think again! Many gases are in fact quite stable and safe. In the world of welding they have even come to be vitally important. Welding processes such as MIG/MAG, TIG and plasma have come to depend on these so-called shielding gases to produce a stable and flawless weld just like we depend on the air we breathe. Which is why we speak of gas shielded arc…

From TIG Welding System to Multiprocess Welding System: The Development of the New iWave Series in 10 Steps

Tried and tested countless times, with proven handling and outstanding weld seam quality: So why even bother making further improvements to the TIG welding system? Our iWave series proves that it was absolutely worth the effort: Its multiprocess welding systems are suitable for both TIG and MIG/MAG welding, 100% prepared for Industry 4.0, and offer significantly optimized welding processes. But how did the initial concepts for a new TIG welding system become a market-ready multiprocess system?…

Cleaning stainless steel welds: Three tried-and-tested methods compared

Why should you clean stainless steel welds thoroughly after TIG welding? There are two compelling reasons for this. Firstly, it just looks better. And secondly – and this is the real clincher – properly cleaning welds prevents corrosion, i.e., the long-term degradation of the stainless steel. So, the only question that remains is how best to remove annealing colors from TIG welds.…

What does an electric arc technician do?

It’s like playing with fire: arc plasma at up to 20,000 degrees, dramatic changes from one microsecond to the next, and a huge impact on materials. Natural lightning and arcs during welding work according to the same physical principles. But what’s the role of electric arc technicians? To transform something inherently unstable, volatile, and intangible into something steady and reliable. In other words, to develop a stable arc that makes welding fast, convenient, and reliable.…

Pulsing as a universal solution in steel welding

An all-singing, all-dancing solution? In many areas of life, they still don’t exist yet. But is it true that there is now ONE universal solution in the field of welding systems? Is there one system to suit all applications? Is there ONE ideal process? Of course not. However, we are talking exclusively about the area of steel welding and the MAG process. One thing quickly becomes clear: where pulsing is used, many things become much easier, and this also applies…

Highly professional TIG welding: HF ignition

HF-Zündung

Driving on ice: assuming you have at least four wheels and have undergone intensive training, this should be possible. However, if the driver wishes to drive on mountain slopes with high precision and maximum safety, a vehicle with all-wheel drive is advisable – almost as a basic requirement. There are also parallels with TIG welding here. The maximum quality welding process which demands fine dexterity is also suitable for domestic use with simple touchdown ignition. However, for anyone wanting to…

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…
