The Importance of Microstructure in Welding

Ini adalah microstructure of welded joints influences severala key realties, including:

  • Pertama; FLT: 0; 3; Strength: 501; FLT: 1 After3; The vogement of grains and phases affects te tensile and yield syush.
  • Pertama; FLT: 0: 0 = 3; Toughness:
  • FLT: 0 = 033. Fatigue Resistance: 01.1; FLT: 1: 1 FLT; 1f 3; Microstructutul suffery a cruciali role in material haw respond to cyclilic loading.
  • Pertama, FLT: 0 MRT; O MRT; Corrosion Resistance:
