Specialized Welding Services: MIG/MAG and TIG
Welding Technologies at Alpha Group
Selecting the appropriate welding method is essential to achieving optimal mechanical properties and weld aesthetics. At Alpha Group, we utilize two primary, complementary methods:
MIG/MAG Welding
MIG/MAG welding (methods 131 and 135 according to ISO 4063) is our primary technique for creating fast, cost-effective joints in thick materials. This is an arc welding process in which a consumable wire electrode is continuously fed through the welding gun.
MAG (Metal Active Gas): Used for welding carbon, structural, and low-alloy steels. It utilizes active gases (such as $CO_2$ or argon/$CO_2$ mixtures) that actively participate in the chemical process within the arc. This method is characterized by high productivity and deep penetration, making it ideal for high-volume production and high-strength components, such as frames, machine housings, and load-bearing structures.
MIG (Metal Inert Gas): Primarily used for welding aluminum, stainless (acid-resistant) steels, and other non-ferrous metals. It uses inert gases (such as argon or helium) that do not react with the weld pool. This ensures a clean weld and minimizes the risk of defects.
What this means for Alpha Group clients: Fast turnaround on large-scale projects and economical joining of structural components while maintaining all required strength standards.
TIG Welding
TIG welding (method 141 according to ISO 4063) is a technique focused on the highest quality and precision. In this process, a non-consumable tungsten electrode generates the arc, while the filler material is fed either manually or mechanically. The welding takes place under a shield of inert gas (pure argon).
Applications: TIG is ideal for welding stainless (acid-resistant) steels, aluminum, and thin-gauge sheet metal. This method is indispensable whenever weld aesthetics and joint integrity are paramount, such as in the food and pharmaceutical industries, or the production of pressure vessels and pipelines.
Key Advantages: TIG welds are exceptionally clean and smooth, featuring zero spatter and excellent mechanical properties. This technique provides total control over the process, which is essential when working with heat-sensitive materials.
What this means for Alpha Group clients: A guarantee of aesthetic, high-precision, and defect-free welds—critical for visible components or those that come into direct contact with a product.
