Description
The carbon steel and low-alloy steel welding wire produced by Zhima Xing Welding Material Co.,LTD is used to protect gas in electric-arc welding. It has excellent welding performance and welds with co2 as protection gas. The welding wire is steady to transfer wire, the welding line is formed beautifully, the welding fog and splash is little and also it has good fluidity and anti-crack resistance. The welding slag is thin and easy to fall and the welding line has good breaking strength and anti-low temperature impact resistant performance.
Application
1. mineral machineries,engineer machineries,ships,bridges,pressure vessels, building constructions;
2. welding of other 500Mpa level carbon steel and low alloy steel
3. high-speed welding of light gauge plate and pipe line steel.
