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

Posted on 16. March 2022

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?

Posted on 16. March 2022

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

Posted on 27. September 2021

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

Posted on 11. January 2021

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

Posted on 4. December 2020

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?

Posted on 29. October 2020

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?

Posted on 13. October 2020

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?…

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…
