Automatic Gouging Machine 
Girth Seam Gouging Machine is designed for grinding of inside tank girth seam. By use automatic disk gouging, it highly improves the grinding efficiency.
It has features as following:
- Gouging by gouging disk;
- Gouging speed:0-2600mm/min;
- Gouging efficiency is 15 times of manual gouging;
- Widely used in the gouging of carbon steel, high strength steel, low temperature steel, stainless steel and so on;
- Saving labors and costs
