The system is specially designed for pipe to pipಞe butt joint TIG orbi🍒tal welding, and the welding range could reach Φ300mm and above.

  Cold wire/hot wire TIG DCꦺ/pulse all-position automatic welding crawling trolley for larg🎃e diameter pipe and pipe;

  Pipes with different diameters are equඣipped with different positioning guide rings, and the guide rings are driven by rack and pinion;

  Self-contained integrated wire feeder realizes unwinding wire feedin🌜g;

  Automatic arc length tracking, yaw ꩲ🅺cover function;

&nbs𒁃p; The efficiency of hot wire welding is 3~5 times higher than that of cold wire wꦆelding;

  The groove form of the woꦺrkpiece can be V-shaped or U-shaped;

  S𒁏uitable for welding carbon steel, stainless s꧃teel, duplex steel and other alloy materials;
