Welding technology is facing ever-increasing demands. Processes must be made more efficient, safer and more environmentally friendly, while at the same time the highest quality standards must be maintained.
Particularly low-spatter and silicate-free welding is a decisive factor in saving time and costs and increasing productivity. Low-activity shielding gases such as Arcal 14, Teral 24-7 and Arcal M24 from Air Liquide offer tailor-made solutions for the industry. “A precise weld seam without spatter and silicates is the key to higher productivity and cost efficiency today,” explains Norbert Semsch, expert for gases for welding and cutting at Air Liquide.
Why low-spatter and silicate-free welding is essential
Flawless weld seams with minimal reworking are the goal of every welding application. Spatter, which occurs when molten metal comes into contact with the welding surface, and silicates, which appear as glass-like slag on the seam surface, cause additional work steps such as grinding or cleaning. These processes are time-consuming and cost-intensive. In addition, the reduction of welding fumes is a growing concern. The particles and gases produced affect the health of welders and the environment. “Our low-active gases significantly minimize these undesirable by-products and thus contribute to a safer working environment,” emphasizes Semsch.

Low-active shielding gases optimize welding technology
Low-active shielding gases combine argon as the base gas with precisely balanced proportions of oxygen and carbon dioxide. This mixture has a positive effect on the entire welding process:
– Argon stabilizes the arc and protects the weld seam from oxidation.
– Oxygen improves the flowability of the molten bath, reduces the surface tension and minimizes splashing.
– Carbon dioxide ensures deep penetration and stabilizes the arc.
The targeted composition of these gases offers an optimum balance between penetration, process stability and seam quality. “With our shielding gases, we enable clean, smooth seams and efficient production at the same time,” says Semsch.
A look into the future of welding technology
The demands placed on weld seams are constantly increasing, especially due to modern coatings and high-precision applications. Low-activity gases such as Arcal 14, Teral 24-7 and Arcal M24 offer solutions that not only improve quality and efficiency, but also make the working environment safer. “Our gases are more than just technical aids. They are an essential part of modern production processes and play a key role in ensuring that companies remain competitive,” concludes Semsch. With innovative shielding gas solutions such as the Arcal line, Air Liquide is setting new standards in welding technology – for efficient, safe and sustainable production processes.
