Abstract
The invention discloses a welding method of copper-nickel alloys. The welding method comprises the following steps that a groove is machined, and two to-be-welded copper-nickel alloy plates are machined into the groove; the plates are ground, and the surfaces of the copper-nickel alloy plates on the two sides of the groove are ground till the metal luster is exposed; the two copper-nickel alloy plates are erected by a certain included angle; welding equipment is selected and is a direct current argon arc welding electric welding machine, the diameter of a nozzle of a welding gun is phi 14 mm,and the distance between the nozzle and the copper-nickel alloy plates ranges from 10 mm to 15 mm; a tungsten rod serves as the electrode of the direct current argon arc welding electric welding machine, argon serves as protective gas, the purity is 99.7%, and the flow ranges from 14 L / min to 15 L / min; multi-layer welding is carried out, wherein multi-layer welding is carried out according to thethickness of the copper-nickel alloy plates; and evaluation testing is carried out, wherein evaluation testing is carried out on the multiple welded copper-nickel alloy plates. By means of the weldingmethod, welding to the copper-nickel alloys is achieved, and the quality is high after welding.
Description
technical field [0001] The invention relates to the field of welding, in particular to a copper-nickel alloy welding method. Background technique [0002] B30 copper-nickel binary alloy has good corrosion resistance and high mechanical strength, and is not easy to produce stress corrosion cracks. It has high chemical stability in corrosive media such as seawater and various salt solutions of organic acids. The copper-nickel alloy is made into various corrosion-resistant components such as condensers, heat exchangers, and lye storage tanks in shipbuilding, power stations, and petrochemical industries. [0003] When making these corrosion-resistant components from copper-nickel binary alloys, welding of copper-nickel binary alloys is required. Therefore, how to use a simple and convenient copper-nickel alloy welding method to make the corrosion-resistant components after welding have good quality and high safety is very necessary.
