Abstract
The invention discloses an impact-resistant thin-diameter self-protection bead weld flux-cored wire, which belongs to the field of the welding in the material processing engineering. The impact-resistant thin-diameter self-protection bead weld flux-cored wire is mainly applied to the bead weld repairing of mechanical parts which resist massive impacts of materials such as rock, mud and mineral. The impact-resistant thin-diameter self-protection bead weld flux-cored wire is characterized in that the core comprises the following ingredients in parts by weight: 10-50% of high carbon ferro-chrome, 1-4% of ferromolybdenum, 1-4% of high-silicon ferrosilicon, 8-14% of manganese metal, 25-35% of ferrovanadium, 2-6% of ferroboron, 5-8% of ferrocolumbium, 2-5% of aluminium powder, 3-6% of rutile, 2-5% of potassium carbonate and 1-3% of sodium fluoride. The invention aims to overcome the deficiencies of the traditional bead weld repairing method and material, and the impact-resistant thin-diameter self-protection bead weld flux-cored wire which can carry out field welding and bear massive attack, has a small thermal input in the bead weld process and has a small possibility of causing the thermal deformation of a workpiece is provided.
Description
Technical field
Belong to the field of thermal spray in the Materials Processing Engineering, the manufacturing of each type component under the industrial and mineral conditions such as that this invention is mainly used in is wear-resisting, corrosion-resistant, high temperature resistant, shock resistance, reparation and pre-protection.
Background technology
Some components of machine such as fan blade, turbine blade, bagger blade, jaw etc. suffer serious impact in the course of the work, need frequently to change, and have increased cost greatly.And adopt the method for built-up welding that the parts that lost efficacy are carried out the built-up welding reparation, and because at most only accounting for, rehabilitation expense more renews 1/3rd of part, can save cost greatly.Therefore, built-up welding is a kind of recovery technique of present extensive use.No matter but all there is defective greatly in present recovery technique on method and material, from overlaying method, main welding rod and the gas protection wire of adopting comes built-up welding now, and welding rod is because utilization rate is low, and not only production efficiency is low, and the increase cost; The reparation of many parts all is on-the-spot open-air the reparation mostly, in case wind-force greater than level Four, gas protection welding just can not normally be carried out.And above-mentioned parts all belongs to thin, and when adopting traditional welding method (welding rod and 1.6mm gas protection wire) built-up welding, the heat input is too big, very easily causes workpiece deformation.
The diameter of welding wire directly has influence on the heat input of workpiece, thereby influences the distortion of workpiece.The relation of gage of wire and welding procedure is as shown in table 1.
Problem to be solved by this invention; overcome the deficiency of above-mentioned traditional build-up welding repair method and material exactly; provide a kind of can open-air welding, can suffer serious impact and in the weld deposit process heat input less, be difficult for causing the shock-resistant thin footpath self-shield flux-cored wire of workpiece thermal deformation.
Summary of the invention
Wear and shock-resistant self protection pile-up welding flux core welding wire provided by the present invention is characterized in that, described drug core component quality percentage composition scope is as follows:

Wherein each component effect is as follows:
High carbon ferro-chrome: to the weld metal transition alloy elements;
Molybdenum-iron: to the weld metal transition alloy elements;
High silicon ferrosilicon: to the weld metal transition alloy elements, deoxidation, protection molten bath;
Manganese metal: to the weld metal transition alloy elements, deoxidation, protection molten bath;
Vanadium iron: to the weld metal transition alloy elements;
Ferro-boron: crystal grain thinning, improve weld strength;
Ferro-niobium: to the weld metal transition alloy elements;
Aluminium powder: denitrogenation, stable arc;
Rutile: slag making, protection molten bath;
Potash: stable arc;
Sodium fluoride: stable arc.
Preparation method of the present invention adopts prior art, may further comprise the steps:
(width is 8 ~ 12mm, and thickness is 0.3 ~ 0.6mm) to be rolled into U-shaped, adds in the U-lag to account for welding wire of the present invention again with steel band
The powder core of the present invention of gross weight 15 ~ 35%;
U-lag is healed up, make powder core parcel wherein, by wire drawing die, by road drawing, tube reducing, its diameter is reached
0.8 ~ 1.2mm obtains final products.
