Abstract
The invention relates to a special nuclear power welding rod matched with an SA-738 Grade B steel plate for an AP-1000 pressurized water reactor containment vessel, and the formula of the coating of the welding rod comprises the following components in parts by weight: 35-50 parts of marble, 18-30 parts of fluorite, 5-10 parts of electrolytic manganese, 5-10 parts of quartz, 10-15 parts of rutile, 8-18 parts of iron powder, 5-10 parts of silicon iron, 0.5-1.5 parts of CMC and 0.8-1.6 part of soda ash. The welding rod has the characteristics of less splashing, beautiful forming and easiness in deslagging, all position welding can be carried out, and the performance requirements of a welding material matched with the SA-738 Grade B steel plate can be completely met.
Description
Technical field
The invention belongs to the flux material field, relate to a kind of low-alloy steel welding rod of nuclear power special use.
Background technology
Along with the development of China's nuclear power, nuclear power domesticizes at the eyebrows and eyelashes with wlding.Welding is the critical process during the nuclear bearing device is made, and welding point is examined the weak link of bearing device often.Therefore, the nuclear reactor bearing device occupies crucial status with welding material and welding procedure in design, construction and the man-rate of nuclear power station, be directly connected to the feasibility and the security of the construction of nuclear power station.Just be based on high request for security, nuclear-electric welding material have than common wlding higher enter barrier, but simultaneously, because domestic wlding quality and quality and external wlding still have certain gap, the nuclear power nuclear island wlding of pressurized water reactor (PWR), steam generator nucleuses such as (SG) depends on import substantially, so nuclear-electric welding material production domesticization space is huge.At present domestic also do not have and the AP-1000 type presurized water reactor containment supporting welding material of SA-738Grade B steel plate, therefore development is supporting and satisfy the welding material of nuclear power required standard system and quality assurance system with steel plate, form the production technology of the supporting welding material of nuclear power plant containment shell, help country and save cost, the control quality guarantees the nuclear power engineering progress.
Summary of the invention
In order to fill up the vacancy of domestic market nuclear power special welding material, the invention provides a kind of and the supporting low hydrogen type low-alloy steel welding rod of three generations's nuclear power AP1000 steel containment vessel (SA738B steel plate).The present invention's selected by to alloy system adjusted prescription, obtains good welding procedure and deposited metal performance.
The present invention solves the technical method that its technical problem takes: by analyzing and the characteristic of research material, through proportioning test repeatedly, the chemical coating of welding electrode prescription (in weight proportion) of selected employing is marble 35-50, fluorite 18-30, electrolytic manganese 5-10, quartzy 5-10, rutile 10-15, iron powder 8-18, ferrosilicon 5-10, CMC0.5-1.5, soda ash 0.8-1.6.Be made into welding rod crust spice by said ratio, add waterglass or other adhesive, be coated on H08A special-purpose steel core wire or other high-quality steel core wire through electrode extrusion press and make welding rod, drying typing again is made for the welding rod of all sizes such as diameter of phi 2.5, Φ 3.2, Φ 4.0, Φ 5.0.
The present invention is a welding rod of material being matched, adjusted composition.Electrode coating of the present invention is mainly protected with slag, by component and alloy material in the adjustment coating, thereby obtains satisfied deposited metal performance.Show through test of many times, it have splash less, moulding is attractive in appearance, easily take off advantage such as slag, can carry out all-position welding, satisfy fully and the supporting performance requirement of SA-738Grade B steel plate with welding material.
