Flux cored wire is a new welding material. Variety and amount of domestic flux cored wire are growing . There are advantages compared with solid wire flux cored wire.
⑴ advantages:
1) welding of various steel products. Ingredients and proportions adaptable to adjust the flux is extremely convenient and easy. The chemical composition of the weld can be provided required.
2) good process performance. Weld appearance using gas slag joint protection, get a good shape. Join arc stabilizer arc stability. Uniform droplet transfer.
3) deposition speed. High production efficiency at the same flux cored welding current large current density, melting fast, its deposition rate of about 85% -90%. Productivity is about 3-5 times higher than SMAW.
4) large welding current available all-position welding.
