Date:2019-05-30 Author: Click:

Sj102 flux for roller protection is a special flux for steel structure, with excellent welding process performance, stable arc combustion, easy slag removal and beautiful weld formation. The following is a brief introduction to the process of sj102 flux used in steel structure.






1. The performance of cutting and welding equipment for sj102 steel structure fabrication and installation shall meet the requirements of the selected process.






2. Before flame cutting, rust spots and oil stains on the steel surface within 50 mm from the cutting edge shall be removed. The oxygen purity should reach 99.5% - 99.8%, and propane should reach the national standard purity. The cutting process of oxygen, acetylene and propane should meet the requirements of parameters.






3. Sj102 welding groove can be cut by flame or machined, but the groove type and size after machining shall meet the requirements. During flame cutting, there should be no crack on the incision and no edge defect larger than 1.0 mm. After cutting, the oxide, nugget and spatter on the edge should be removed. There should be no steps on the surface during machining.
