Why Choose Us?

Professional Welding Supplies Manufacturer.

Oldwelders (Luoyang Hanrong welding materials Co., Ltd. ) is a professional welding machine, equipment and material manufacturers with wide product range covers automatic submerged arc welding, electroslag pressure welding, smelting flux, new flux and sintering flux, the plant covers an area of 1000 square meters and has six production lines, which can supply 100 tons a day. The raw materials of the flux products produced by the company are excellent dolomite, bauxite, cryolite, silica, fluorine ore and other ores, which are melted at 2000 °C. Our fluxes have three processes: melting, sintering and crushing. After finishing, grinding, sorting, granulating and packaging, we make welding slag with stable quality. The fluxes are mainly HJ431 and sj101, HJ107 and hj260. The product quality is stable and the price is reasonable. At present, we have established supply relations with many dealers all over the country. 

In addition to submerged arc flux products, the company also produces and sells brown corundum (BFA), grinding wheel, welding wire, flux medicine box and other related welding supplies. The company began to carry out export business in May 2020. Its products are exported to Brazil, Thailand and other countries, and the quality has been recognized and praised by overseas customers.
