Sustainable Welding in Practice

Posted on 23. October 2019

Our environment can only take so much. That is why sustainable action and the conscious use of resources and energy is extremely important. Sustainable Welding is also playing an increasingly important role in industrial production. A number of factors are decisive for welding technology, including the correct welding process and a higher welding speed combined with less rework. How does sustainable welding work? The use of modern and sophisticated welding technology is extremely important when it comes to achieving sustainable…

Underwater Welding: Weightless Welding Under Probably the Toughest Conditions

Posted on 10. September 2019

The deep underwater world of our planet can be as alien as outer space. Bridges, oil platforms, and other structures reach into and over these areas requiring skilled workers to build and maintain them. Above the surface, welding, cutting, and assembling these structures requires only the training and skill to do the job. Performing those same jobs underwater requires an entirely new set of skills, understanding, and equipment. Welcome to the world of commercial diving, and more specifically, underwater welding.…

What is … tandem welding?

Posted on 24. June 2019

Tandem welding represents a milestone in the history of gas metal arc welding (GMAW). Perfect welding quality and high productivity were key considerations in its development, since welding processes that fulfill these conditions are increasingly in demand. But, what exactly is tandem welding? What advantages does the process offer and where is it used? How does it differ from double-wire welding? Basics The process involves high performance MIG/MAG welding using two wire electrodes. It is only used in fully automated…

Multiprocess Welding Systems—What Is the Purpose?

Posted on 23. May 2019

Multiprozess-Schweissen-MIGMAG-WIG-EHand

Metalwork fitters “Heißeisen” have a major order—the job involves processing a wide range of materials in a modern building complex: Numerous shelving units made from unalloyed steel in the storeroom and the chrome-nickel stair railings are joined using the MAG welding process. For detailed work on the handrail, weld seams now have to be 100% satisfactory both in terms of visual appearance and touch; this calls for the TIG process. A literal highpoint for “Heißeisen” was the final assembly work…

Welding for Space Travel: The Ultimate Challenge

Posted on 11. October 2018

Space travel is undoubtedly the biggest adventure in the history of mankind. Satellites, space flights, and space stations head ever deeper into the endless expanse of the universe – all the while braving conditions that are unlike anything that can be found on Earth. In order to guarantee the safety of those onboard and the machinery, the quality requirements for manufacturing are exceptionally high, including for the welding technology. The challenges of the cosmos Right from the beginning of…

Renting welding equipment instead of buying it? Here’s why.

Posted on 25. September 2018

Imagine the scenario: you have landed a huge order for a considerable steel structure, but you do not have enough skilled workers or welding equipment at your company. No problem, you will immediately strengthen your team with agency staff that can be recruited at short notice. But you also need additional welding equipment to cope with the peak workload. What do you do? You could buy some new machines quickly, but at a high, and not necessarily fully foreseeable, cost.…

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…
