Abstract
The invention discloses a fluoride welding rod which comprises a welding core and a coating coated on the outer wall of the welding core. The welding core is H08A. The fluoride welding rod is characterized in that the coating accounts for 45-50% of total weight of the welding rod, and taking total weight of the coating as a reference, the coating is composed of, by weight, 30-42% of rutile, 1.5-5% of titanium dioxide, 9-18% of potassium feldspar, 7-12% of cryolite, 6-10% of CaCO3, 3-8% of zircon sand, 4.5-10% of CaF2, 4-8% of NaF, 3-6% of metal manganese, 8-14% of metal chromium, 2-6% of metal nickel and3-7% of ferromolybdenum. Amount of diffusible hydrogen in a welding seam is lowered during welding by using the welding rod, gas traces in the formed welding seam are reduced, and the fluoride welding rod is used in a factory.
Description
Technical field
The present invention relates to the welding rod using in a kind of factory.
Background technology
Existing flux-cored electrode is generally used in the arc welding of base steel metal.These welding rods produce high-intensity welding with high speed of welding conventionally in single track welding and multiple tracks welding.Prepare these welding rods in order to provide solid, in fact atresia weld seam, it has tensile strength, ductility and impact strength to meet the needed final use in various fields.In the process of gas-shielded flux-cored wire arc welding, observe the phenomenon of gas tracking, wherein arrived the vermicular depression of class at the surface observation of weld seam.This phenomenon is mainly to observe in cooling fast slag system [rutile (rutile) base], and wherein slag solidifies more fasterly than weldpool.Due to the rapid solidification of slag, the gas shedding from the weld seam of fusing is partly kept here, has so just formed depression at face of weld.[0009], in view of the current state in the fill composition field being combined with flux-cored electrode, need a kind of energy to form welding rod high-quality, that gas tracking forms the weld seam of surperficial amount of recess reduction.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of fluoride welding rod of research and design, in order to solve the shortcoming of existing welding rod surface of the work that gas tracking forms depression.The technological means that the present invention adopts is as follows:
A kind of fluoride welding rod, comprising: core wire and coating, and described coating is coated on the outer wall of core wire; Described core wire is H08A; It is characterized in that: described coating accounts for 45～50% of welding rod gross weight, described coating, take the gross weight of coating as benchmark, counts by weight percentage, and the component of described coating comprises:

Metallic nickel: 2～6%;
Molybdenum-iron: 3～7%.
Be 5.40～5.90mm as the external diameter of preferred described welding rod.
The fill composition of described welding rod medicine core contains titanium oxide and is used for regulating the performance of the slag that forms in welding process as main slag forming agent and one or more fluorochemicals, to reduce or eliminate the existence of gas tracking on weld metal.In fill composition, can use and be permitted eurypalynous fluorochemical.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
