JCTD-32
Description:
JCTD-32 self-shielded flux cored wire with DC positive (welding wire connected to the negative), the arc jet, spatter less, and has good welding performance, with a continuous wire, without gas protection, strong wind resistance, production efficiency High, low overall cost, good welding quality and so on.
use:
Suitable for railway rail (U74 ﹑ U71Mn ﹑ PD3 ﹑ rare earth rail) and combined frog wear ﹑ low collapsing, scraping and peeling repair.
