Types of Cracks in Weld:
1.Hydrogen Cracks or Cold Cracks or delayed Cracks.
2.Hot Cracks or Sulphur or Phosphorous Cracks.
Flux Composition:
1: Mn + S Mns ( Slag) Removal of S&P to reduce Hot cracks in weld
2: Mn + P Mnp (Slag)
4.Na + H NaH ( Slag) ( Removal of Hydrogen to reduce Hydrogen Cracks.
5.Ca + H CaH ( Slag)
6.K + H KH
7.Si + O2 SiO2 (Removal of oxygen to reduce stress corrosion cracks in weld.
