Product List

Flux-cored wire welding equipment is the fourth generation of the most advanced welding materials developed rapidly in recent years. It has been widely used in industrial developed countries because of its incomparable advantages of other welding materials, such as high efficiency, excellent workmanship, less spatter, high welding quality and easy automation.
A. Rolling Flux Cored Wire Production Line
The main features of this production line are: large filling ratio can be obtained, and different types of flux-cored wire products can be produced, with high output and low cost. Suitable for carbon steel, hard surfacing, carbide, stainless steel and high alloy type, large diameter flux cored wire production. Disadvantage: It is difficult to adjust because of the large number of rolls.
