| Abstract: | J427GR welding rod is of good welding technology properties with lower diffusible Hydrogen content, fine plasticity and low-temperature flexibility. It is developed by raising suitably the alkalinity in the clinker, controlling the content and burden of the alloy elements in the deposited weld metal, and blending trace elements, etc. analyzed by the methods of orthogonal design and variance analysis. It can be suited to the important welded structures which have strict requirements of the low-temperature impact flexibility. |
