Embodiment Construction
[0013] Forged steel QD785 is used in the construction of a hull, that is, high-strength steel with a yield strength of 785Mpa. The steel has a structure of surfacing copper layer in the pressure-resistant channel locked by the slewing ring, and the copper layer surfacing process The level has a very important impact on the internal quality of the copper layer and the bonding performance with the steel substrate. The high-strength steel surfacing copper layer process of the present invention is used to surfacing the copper layer on the QD785 steel substrate. The process is as follows:
[0014] Welding method: molten inert gas shielded welding, the shielding gas is pure argon, the purity is not less than 99.99%;
[0015] Welding material: SCu6180, that is, S215, with a diameter of φ1.0;
[0016] Welding temperature: preheat 200℃~250℃ before welding, and preheat within 50mm of the area to be surfacing during preheating before welding.
[0017] During the welding process, keep th...
