Abstract
The present invention relates to a solder wire for welding, which is suitable for CO2 gas shielded welding. The operational environment for welding can be at the low temperature of-40 DEG C, and objects are high-strength structural members. The solder wire for welding comprises the following main ingredients: at most 0.15 % of C, 0.2 to 1.0 % of Si, 0.8 to 2.8 % of Mn, 0.03 to 0.3 % of Ti, 0.5 to 3.0 % of Ni and 0.2 to 0.8% of NO. The solder wire of the present invention has low spatter loss rate which can be less than 4%, and high strength which can reach 800MPa. The present invention which has favorable low temperature toughness has the advantages that the impact toughness of Sharpey's samples can be more than 40 Joules (J) at temperature of-40 DEG C, and the impact toughness can be more than 20 Joules (J) at the temperature of-20 DEG C. The present invention is a favorable solder wire.
Description
The present invention is a kind of welding wire that welds usefulness.Be applicable to CO
2Gas shielded arc welding.
CO
2Gas shielded arc welding is widely used in the production practices of high strength component owing to its unique advantage.Therefrom welding wire is also proposed various performance requirements, particularly some member desired strength height and low-temperature flexibility are good.Japanese kokai publication sho 55-114495 discloses the silicon Si of a kind of titaniferous Ti, the welding wire of manganese Mn series, improves CO
2Splashing property in the gas shielded arc welding welding procedure, but just seem not enough to improving intensity and low-temperature flexibility.U.S. Pat 3,527,920 also disclose a kind of high strength welding wire, and this welding wire is not enough to remedy at CO owing to silicon, manganese content are lower
2Silicon in the gas shielded arc welding process, manganese scaling loss and be not suitable for CO
2Gas shielded arc welding.
The objective of the invention is to propose a kind of intensity high and low temperature good toughness, be suitable for the CO of the high-strength structure of welding low temperature service condition
2Welding wire for gas shielded welding.
Technical scheme of the present invention is based on above-mentioned United States Patent (USP), improves the content of silicon Si, manganese Mn, titanium Ti, thereby makes welding wire be applicable to CO
2Gas shielded arc welding, and the effect of intensity high and low temperature good toughness is arranged.
Mainly containing of the prescription of welding wire of the present invention: C :≤0.15%, Si:0.56～1.0%; Mn:1.5～2.8%; Ti:0.03～0.3%, Ni:0.5～3.0%, Mo:0.2～0.8%.
Use the welding wire that prescription of the present invention is made shown in the following table
Numbering C% Si% Mn% Ti% Ni% Mo%
1 0.10 0.61 2.25 0.18 1.85 0.78
2 0.14 0.92 1.54 0.06 0.8 0.25
Make the test for tensile strength of deposited metal, σ with the welding wire that is numbered 1,2
bCan reach more than the 800MPa, the low-temperature impact toughness of subzero 20 ℃ of summer shellfish samples can reach more than 60 joules (J).The low-temperature impact toughness of subzero 40 ℃ of summer shellfish samples can reach more than 40 joules (J).Spatter loss coefficient can reach＜and 4%.
Practice confirms that welding wire of the present invention has the intensity height, and the feature that spatter loss coefficient is low, low-temperature flexibility is good is suitable for carbon dioxide gas arc welding and uses, and is applied to high strength component, service condition low temperature, or even subzero 40 ℃ environment.
