Welding Properties
Manual Metal Arc Welding of Q690D(20mm):
Welding at preheating temperature 100℃ by using heat input of 16KJ/CM;
Impact energy of welding metal: >100J;
Maximum impact energy through Heat Affected Zone: =70J
Tensile strength of welding joint:920MPa, close to base material.
Bending test of welding joint: no cracks shown after root bending and face bending.
Hardness of a quarter welding joint and hardness of root: <350 (HV0.5), corresponding to the microstructure of HAZ at the joint;
Hardness of upper and lower surface in HAZ: ≤400(HV0.5)
Microstructure of welding joint:
1.Weld: mainly bainite;
2.Overheated Zone: mainly bainite, also showing martensite and a small amount of ferrite.
Application
Mainly used in large ships, Bridges, power plant equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery, mining machinery and other large welded structural parts.
