Abstract
The welding electrode is a surfacing welding electrode whose deposited metal is a manganese-boron steel bainite/martensite complex phase structure. The hardness of the deposited metal in an after welding state can reach H<RC> 50 to 60, and the welding electrode has the advantages of dual purpose of an alternating current and a direct current, good processing property and little splash. The welding electrode can be used for the surfacing welding repair of worn parts, such as engineering machines, agricultural machines, crushers, etc.
Description
The invention belongs to surfacing welding alloy and surfacing welding electrode.
The deposited metal that at present domestic and international hardfacing is adopted mostly is chromium-molybdenum alloy system, and chromium-manganese alloy system or high mangaenese steel system are as using heap 212, serial welding rods such as heap 207, heap 256, these alloy systems all adopt high alloy to strengthen alloy consumption height, and element such as chromium, molybdenum costs an arm and a leg, domestic resource shortage.High manganese steel surfacing electrode is the manganese content height not only, and welding technological properties is bad, and deposited metal is prone to crackle, and its application is subjected to certain restriction.
The objective of the invention is to develop few hardfacing alloy of alloy content and welding rod thereof.
Formation of the present invention is with manganese-boron steel core wire, is equipped with a small amount of alloying element of coating transition, so that deposited metal is the manganese-boron steel of bainite/martensite heterogeneous structure.
Particular content of the present invention is to adopt manganese-boron steel core wire, and neutral slag system coating based on the core wire composition, is equipped with the transition of a small amount of alloying element in the coating again, reaches the composition of deposited metal institute palpus.Core wire of the present invention adopts manganese-boron steel welding wire, its composition can be C0.36～0.7%Si0.4～2.0% Mn, 2.0～3.5% B 0.0005～0.0035%, and all the other are Fe(weight %) coating recipe is: marble 16～22 fluorite 5-10 rutile 10～20 micas 5～8 titanium dioxides 10～12 ferrotianiums 8～10 feldspars 6～8 ferromanganese 8～10 ferrosilicon 3-8 graphite 0～2.5
In order to obtain the deposited metal of different carbon content, can adjust the content of graphite in the coating.
The pulverizing of compositions of surfacing metal and granularity etc. are all identical with common process, and no particular requirement is made binding agent with water glass, squeeze medicine machine or oil press production with spiral.
Welding rod of the present invention is not because alloying element passes through the coating transition, so the weight coefficient of welding rod is identical with common structural steel electrode, can simplify extrusion process and minimizing is splashed, and owing to adopt neutral slag system coating, so can AC/DC.The deposited metal of welding rod of the present invention is manganese-boron steel, can be at the as-welded bainite/martensite heterogeneous structure that obtains, and its hardness can reach HRC=50～60, and its friction durability, other resurfacing welding materials than same rigidity were high.
The deposited metal composition of welding rod of the present invention is:
All the other are Fe(weight % for C 0.30～0.7% Si 0.4～2.0% Mn 2.0～3.5% B 0.0005～0.0035%)
When the carbon content of deposited metal is 0.30～0.50%, weldprocedure is stable, and overlay cladding flawless hardness is H
RC=50～55, surfacing hardness can reach H when the carbon content of deposited metal is 0.51～0.70%
RCA small amount of transverse crack may appear in=55～60 overlay cladding surfaces.
Welding rod of the present invention also can add one or both following alloying elements, to improve the deposited metal performance and to improve its hardness in coating on aforementioned coating recipe basis.The alloying element that adds can be Ti, V, Re.
The advantage of welding rod of the present invention is to adopt manganese-boron alloy system, and alloy content is few, and by the coating transition, processing performance is not good for alloy, the as-welded hardness height of deposited metal, and flawless, wear resisting property are good.
No. 1 the core wire composition is:
C 0.36～0.46% Si 0.4～2.0%
Mn 2.0～3.5% B 0.0005～0.0035
Surplus is Fe(weight %)
No. 2 the core wire composition is:
C 0.47～0.7% Si 0.4～2.0%
