What POLYSOUDE does

POLYSOUDE SAS is a privately held French manufacturer of orbital and automated TIG welding equipment, headquartered in Nantes, France, and operating as a member of the Global Welding Technologies group. Founded in 1960, the company specializes in TIG (GTAW) and plasma welding systems, narrow gap welding, mechanized orbital tube and pipe welding heads, and weld overlay/cladding solutions. Its proprietary TIGer bi-cathode weld overlay technology, developed in 2013, enables deposition rates exceeding 1,700 mm/min, and the Smart Welding Station P3 UHP (17 kg) is positioned as the lightest automatic power source on the market with WiFi touchscreen control and OPC UA Industry 4.0 connectivity.

The company serves highly regulated, mission-critical industrial verticals including aerospace (high-pressure tube systems with over 1,500 welds per aircraft), nuclear and fossil power generation (with documented involvement in the ITER project), semiconductors (ultra-high-purity gas lines), pharmaceuticals and biotechnology, food/beverage/dairy, oil and gas, and chemical processing. Revenue is generated primarily through capital equipment sales (Smart Welding Stations P3/P4/P6 series, UHP closed-chamber heads, MW/MU IV/TS heads, Polycar carriages) supplemented by recurring spare parts and consumables, technical services, calibration/repair, training, equipment rental, and retrofit/upgrade programs. Distribution combines wholly-owned subsidiaries in the USA, UK, China, Italy, Germany, and Benelux with exclusive regional distributors (e.g., Banner Industries for the US semiconductor market).

POLYSOUDE employs 251–500 staff and operates through a sales-led model with field enterprise sales, application specialists, and active participation in global trade events (FABTECH, ADIPEC, SEMICON, ACHEMA, Schweissen & Schneiden, World Nuclear Exhibition). Pricing is not publicly disclosed; a 24-month warranty on Smart Welding Stations was introduced in 2024. The company maintains a multilingual website in seven languages and runs content marketing through a knowledge center and YouTube channel.

Core offering

POLYSOUDE designs and manufactures orbital welding equipment for tube and pipe welding applications, including TIG (GTAW) power sources, welding heads, carriage systems, plasma welding solutions, and weld overlay/cladding equipment. The company focuses on automated and mechanized welding solutions for industrial production environments.

Product overview

POLYSOUDE offers a comprehensive portfolio of orbital and automated TIG welding equipment. The core offering centers on Smart Welding Stations (P3 UHP, P4, P6) that serve as power sources for a range of welding heads. Welding head portfolio includes closed-chamber UHP series (UHP 1000, UHP 1025, UHP-250/500/625) and MW range for high-purity applications, open-chamber MU IV and TS heads for standard orbital welding, and carriage-type Polycar heads (51 LRC, 100 LRC, 100 LAC) for mechanized applications. Specialized technology includes TIGer bi-cathode weld overlay for cladding at speeds over 1,700 mm/min, plasma welding, and narrow gap welding. Add-on modules include Polyview HD video monitoring for real-time weld observation. The product line serves demanding industries including semiconductors, pharmaceuticals, aerospace, nuclear, and food/beverage requiring high-purity and ultra-high-purity welding standards.
