JCTD-33
Description:
JCTD-33 self-shielded flux cored wire is DC positive (wire connected to the negative), the arc jet, spatter less, and has good welding process performance, without gas protection, strong wind resistance, continuous wire, to achieve rail butt The automatic welding, high production efficiency, low overall cost, good welding quality of a new welding method.
use:
For rail rail (U74 ﹑ U71Mn ﹑ PD3 ﹑ rare earth rail) joint continuous welding.
