Particle flux with a certain degree requirements, the right size to make a certain permeability Welding Electrode , revealing a continuous arc welding process does not prevent the formation of pores of air pollution pool. Flux is generally divided into two types, a common size is 2.5-0.45mm (8-40 mesh), the other is fine-grained 1.43-0.28 mm (10-60 mesh). Less than the specified size of the powder is generally not more than 5%, greater than the specified size is generally greater than 2% of the meal, to make the distribution of particle size on the Nickel Alloy Welding Electrodes detection test and control, used to determine the welding current.
