The EH36 marine steel plate yield strength is ≥355MPa, the tensile strength ≥490MPa, and the welding material should be the welding material that matches the grade of the base metal. Therefore, the front FCB method welding material uses the Japanese Kobelco welding wire (3Y grade), the grade is US- 36. The specifications are respectively φ4.8mm and φ6.4mm; the surface flux is PF-I55E, and the back flux is PF-I50R.
The reverse SAW finally adopted ESAB 5Y grade welding consumables after many tests: the welding wire grade is Autrod 13.27, the specification is φ 4mm; the flux is Flux 10.62.
Welding groove and bead design, the size of EH36 marine steel plate test plate is 2000mm*1500mm*49mm, and the test plate is Y-shaped groove. The bevel of the test board and the 20mm on both sides of the weld should be polished to remove the primer and oxide scale. After polishing, the EH36 marine steel plate test board should be positioned and assembled.
