Effect of micro-additions of barium on the quality of industrial pipeline welded joints
- 20 Downloads
The effect of barium on the desphosphorization of weld metal of cold-resistant steels is studied. The optimum concentration of barium metal in the electrode coating and phosphorus in the weld metal is established, and this makes it possible to provide a high strain capacity and crack resistance for welded joint metal made by electrodes with the basic form of a coating.
