Welding site should be cleaned, do not mix the debris into the flux, including flux pad flux should be issued according to regulations, preferably at about 50℃ to be used, timely do a good job of flux recycling, to avoid pollution; Continuous use of flux with 8 mesh and 40 mesh sieve respectively and remove impurities and fine powder, mixed with three times the new flux after use. Before use, it must be dried at 250-350℃ and kept for 2 hours. After drying, it should be stored in an incubator at 100-150℃ for next use. It is forbidden to store in the open air. In case of complex site or relatively high humidity, timely manage the operation site, keep it clean, conduct necessary tests of flux resistance to moisture and mechanical mixture, control moisture absorption rate and mechanical inclusions, avoid disorderly heap and confusion of flux.
Sintered flux is mainly used for automatic submerged arc welding. The welded steel includes all kinds of carbon structural steel, stainless steel, heat resistant steel and composite steel. It is widely used in shipbuilding, boiler, chemical container, bridge, lifting machinery and metallurgical machinery manufacturing industry. The unique advantages of submerged arc welding are no pollution and no arc radiation.
