Embodiment Construction

[0024] The present invention will be further elaborated below in combination with specific embodiments.

[0025] A gas-shielded solid welding wire for steel with a yield strength of 460MPa, comprising the following components: by mass percentage, C: 0.04%-0.12%, Mn: 0.9%-1.4%, Si: 0.4%-0.8%, Ni: 0.8%-1.1%, Mo: 0.08%-0.2%, Ti: 0.02%-0.05%, B: 0.0015%-0.0030%, Cu: 0.20%-0.25%, Al≤0.01%, S≤0.010%, P≤ 0.020%, O≤0.005%, N≤0.005%, Ce: 0.0050%-0.010%, the balance is iron powder and unavoidable impurities.

[0026] A method for preparing a gas-shielded solid welding wire for steel with a yield strength of 460MPa as described above: take each component according to the mass percentage, smelt the steel ingot, roll the wire rod, anneal the wire rod, draw and reduce the diameter, finish drawing and The copper plating process finally obtains ΦY1.2mm finished welding wire.

[0027] Examples 1-5 are all high-toughness gas-shielded solid welding wires suitable for 460MPa steel. The composi...

Abstract

The invention relates to a gas shielded solid welding wire used for steel with the yield strength being 460 MPa and a manufacturing method. The gas shielded solid welding wire comprises, by mass, 0.04%-0.12% of C, 0.9%-1.4% of Mn, 0.4%-0.8% of Si, 0.8%-1.1% of Ni, 0.08%-0.2% of Mo, 0.02%-0.05% of Ti, 0.0015%-0.0030% of B, 0.20%-0.25% of Cu, less than or equal to 0.01% of Al, less than or equal to0.010% of S, less than or equal to 0.020% of P, less than or equal to 0.005% of O, less than or equal to 0.005% of N, 0.0050%-0.010% of Ce, and the balance iron powder and unavoidable impurities. Whengas shielded welding with 80% of Ar and 20% of CO2 is conducted, the mechanical properties of deposited metal reach welding requirements of steel with the yield strength being 460 MPa and used for marine engineering, impact energy at -40 DEG C is over 120 J, and NDT is below -60 DEG C.

Description

technical field [0001] The invention relates to the field of welding materials, in particular to a gas-shielded solid welding wire for steel with a yield strength of 460MPa and a manufacturing method thereof. Background technique [0002] Steel plates with a yield strength of 460MPa are widely used in high-end technical fields such as marine engineering, construction machinery, and bridge construction. Structural steel plates in these fields are generally thicker, and the service conditions are relatively harsh, so higher requirements are put forward for the corresponding welding materials: (1) Good welding processability, which can meet the welding needs of different positions, and can adapt to many (2) It has excellent low temperature toughness and good impact value at -40°C. In addition, due to the harsh service environment of marine engineering, the drop weight test can be used to measure the zero plastic transition temperature (NDT) of steel, which can characterize the...
