Tricathode TIG/Plasma


WELDING IN LINE PIPE INSTALLATION
 Applications : Lincoln Electric proposes solutions for in line pipe welding to be integrated into pipe mills:
● Monocathode installation with MEC4 TIG torch for tube thickness 0.5 to 3 mm,
● Monocathode installation with SP7 plasma torch for tube thickness 2.5 to 8 mm,
● Tricathode installation with E16 torch for tube thickness 0.5 to 1.5 mm,
● Tricathode installation with E25 torch for tube thickness 1 to 3.5 mm,
● Tricathode installation with combination of TIG + PLASMA + TIG torches for tube thickness 2.5 to 8 mm,

  

  

Process: TRICATHODE welding consists of a sequence of three dual-flow TIG processes using a special welding torch. The first arc is fitted with an electromagnectic arc deviation device. Compared to other welding processes used for this type of fabrication, Lincoln Electric’s TRICATHODE process is of particular interest in terms of performance flexibility, investment/performance ratio and operating costs.
