Weldability |
Automatic submerged arc welding produce austenitic wire for manual two-sided, the back weld of the root and width of the weld pad in the cutting not less than 15 mm. |
Macrostructure and pollution |
The macrostructure of the forgings on the other 14-1-3085-80 should not have traces of shrinkage, porosity, cracks, bubbles, placenow and foreign inclusions visible to the naked eye. Evaluation of the macrostructure is produced in the points e should not exceed: Central porosity ≤ 2.0 points, for all other types of ≤ 1.0 points according to GOST 10243, layer-by-layer crystallization and the bright circuit ≤ 3.0 points according to GOST 10243. |
