🔩 Weld Mark Cleaning Liquids – Production, Formulation and Properties
Overview:
Weld Mark Cleaning Liquids are specialized formulations designed to remove welding stains, heat tint, oxide films, and discoloration from stainless steel and other metal surfaces.
They play a vital role in metal finishing, fabrication, and maintenance, ensuring a clean, uniform, and corrosion-resistant surface after welding.
These liquids restore the metal’s natural shine and maintain its protective oxide layer, improving both the appearance and durability of welded components.
They are used extensively in industrial equipment, pipelines, construction, and automotive manufacturing where high-quality surface finishing is critical.
Production and Formulation:
Weld mark cleaning liquids are formulated using a balanced combination of acids, surfactants, corrosion inhibitors, and wetting agents.
The production process involves controlled mixing to achieve chemical uniformity and optimal reactivity.
Acids help dissolve welding residues and oxides, while inhibitors protect the base metal from corrosion.
Wetting agents improve penetration into weld areas, ensuring complete cleaning even in fine crevices.
The formulation can be adjusted for manual brushing, spraying, or immersion cleaning, depending on application needs.
The final product is stored in acid-resistant containers for industrial use.
