Rapid Welding has worked with Kemppi since the company opened in 1990. Co-founder and Managing Director Roy Edwards highlighted the principles behind that 36-year partnership, from choosing the right welding solution and supporting equipment throughout its life to addressing the skills shortage and finding the right place for automation and laser welding.

Eurosatory 2026 highlighted a clear shift in modern defence manufacturing. While defence systems are becoming more digital, networked, and autonomous, their foundation remains physical. From armoured vehicles and artillery to industrial resilience, welding quality, steel structures, and production discipline remain paramount to defence readiness.

One of the most important elements in developing welding equipment has long been improving welding processes and creating new process variations. Modern measurement and arc control methods have made a wide range of variations in the arc welding process possible. These advanced welding processes significantly improve welding production efficiency and weld quality. This article presents the special processes and operations developed by Kemppi for MIG/MAG welding.

The welding industry is under constant pressure to improve productivity, maintain high quality, and address a growing shortage of skilled labor. Collaborative robots, or cobots, provide a flexible and efficient way to automate welding tasks without fully replacing the human operator. Kemppi’s cobot solution stands out with its unique approach: a practical, cost-effective combination of proven hand-welding technology and smart integration tools.

Welding equipment faces raised expectations due to more demanding base materials. In the welding of stronger steel grades, Kemppi has optimized arc control as a practical solution. WiseSteel is a MAG welding process developed by Kemppi for welding structural steel. The process can reduce the risk of welding defects at high welding speeds. It also enables the use of the low heat input required for stronger steel grades.

Once a welding machine has reached the end of its life cycle, or a company expands its operations, it's time to find a new best friend for the welder. There is a wide range of welding machines on the market, and in many cases, comparing different brands and models is challenging. What kind of things should be considered when purchasing a welding machine?

A skilled and experienced welder can handle different kinds of material, welding applications and positions – even in demanding conditions. However, it is not only the skills that count – without appropriate high-quality welding equipment, excellent welds are only a dream. The performance of a welding machine also has a direct impact on the time spent on welding tasks. Significant cost-savings are only possible when work is done in minimal time with maximum results.

In MIG/MAG welding, arc ignition plays a key role in welding quality. Any instability will result in the post-weld cleaning of spatters, which eats up resources and hinders productivity in industrial environments. Available in modern welding equipment, new ignition-enhancing technologies offer additional control of the arc and support the craftsmanship of welders.

The quality requirements in welding production increase with the optimization of structures as well as the development of materials and welding processes. Welding defects can, at worst, cause serious accidents and structural damage, so it is important to avoid them and understand the mechanisms that create them. In this text, we present the most common MIG/MAG welding defects and the ways to best avoid them.
