Characteristics of microstructure for welding pieces of maximum strength weld area. Found a structure which contains the nanai hostel af main ingredient is elemental structure premium 18-20 percent and 8-10.5 percent nickel element structure resembles the FCC crystalline and crystalline structure of the wife are makha scattered intergranular carbide. Structural hot-growth impact area is den ไดร์ท. Expansion into the molten puddle and microstructure of weld area 70 percent slash in the impact section, the heat has changed because there is heat. There are grainy, making the new arrangement. Reducing the density of granular chromium carbide and Krone Gregory grainy of the hostel, there are bigger nanai resulted in decreased average hardness values.
