White Martins

What White Martins does

White Martins, headquartered in Rio de Janeiro, Brazil, is the country's leading supplier of industrial, specialty, and medical gases, operating as a wholly-owned subsidiary of Linde PLC. The company was founded in 1912 and maintains the corporate entity White Martins Gases Industriais Ltda. Its product portfolio spans atmospheric gases (oxygen, nitrogen, argon), specialty and electronic gases, medical gases for hospitals and homecare, hydrogen including green hydrogen for industrial decarbonization, and calcium carbide — the latter produced at the largest and most modern facility in Latin America, in continuous operation for nearly 40 years. White Martins complements its gas business with proprietary welding equipment and consumables sold under multiple sub-brands: PROSTAR (wires, rods, and tubular wires), SOLDARC (inverter stick welders), SOLMIG (MIG/MAG machines), SOLTIG (TIG machines), and WM LaserStar (laser welding systems introduced in 2025).

The company serves more than 20 industry verticals in Brazil, including healthcare, food and beverage, electronics, oil and gas, construction, metallurgy and metalworking, chemicals, mining, glass and ceramics, pharmaceuticals and biotechnology, aquaculture, and paper and pulp. Distribution is executed via a multi-modal architecture: direct enterprise sales teams, on-site air separation units, multi-year pipeline (gasoduto) supply contracts, bulk liquid delivery (LIN, LOX, LAR), cylinder logistics, a B2B e-commerce platform for SMB and individual welders, an authorized technical assistance network of 15+ service providers, and a mobile application for customer engagement. Underlying technologies include industrial gas production (air separation), hydrogen generation (including green hydrogen), calcium carbide manufacturing, and inverter-based welding equipment with digital control.

White Martins earns revenue through subscription contracts for industrial and medical gas supply (cylinders, liquid bulk, on-site, pipeline), one-time hardware sales of welding machines, consumables, and accessories, professional services covering Industry 4.0 consulting and decarbonization solutions, and recurring medical gas supply to hospitals and homecare patients. As the Brazilian operational arm of Linde PLC, the company benefits from global R&D and engineering resources while selling under its own long-standing brand.
