Hard facing welding is widely used in equipment manufacturing and repair in steel industry.
Hard facing welding technology can not only restore the size and surface properties of products, but also help to improve the lifetime of products.
Hard facing welding Application
1. Hard facing welding of Casting roller
◆ Welding wire NO.:
ALLOY-414N
◆ Welding process: Open arc welding
◆ Advantage: After hard facing welding, the lifetime of the roller can be increased by at least one time. The open arc welding process is simple and convenient, reducing smoke and dust and improving the working environment; High welding deposit rate, up to 10 kg/hour, and the production efficiency is 3 times of submerged arc welding.
2. Hard facing welding of Distributor Chute 3. Hard facing welding of single tooth roller & grate plate
◆ Welding wire NO.:
ALLOY-145 ◆ Welding wire NO.:
ALLOY-145
◆ Welding process: Open arc welding ◆ Welding process: Open arc welding
◆ Advantage: The lifetime can be more than 3 times longer ◆ Advantage: After welding, it can withstand high temperature
than ordinary high chromium. Generally, it can be used above 650 ℃, and its lifetime can be at least
for 2 campaign periods. doubled.
