Description
Technical field
The invention belongs to welding wire technology fields, and in particular to a kind of wear-resisting welding wire with flux core.
Background technique
It usually requires to have worn away the built-up welding of position welding material in wear resistant tools or jig when maintenance wear resistant tools or jig
Filling, then using machining by dimensioned to required precision range.It is welded currently on the market dedicated for the medicine core of built-up welding
The HRC hardness number of silk is 35-60 or so, and the hardness of overlay cladding is too high, and it is big to machine difficulty after maintenance, especially maintenance tool or
Since machining is difficult when jig, if being directly difficult to control size by repair by welding.If not using bead welding wire, and use
The flux-cored wire of general structural steel welds, and welding layer HV hardness also only has 200 or so, and surfacing hardness is relatively low, after maintenance
Tool or jig wearability are inadequate.Furthermore import is depended on dedicated for the flux-cored wire of built-up welding at present, price is very expensive.
Summary of the invention
The purpose of the present invention is to provide a kind of wear-resisting welding wire with flux core, to solve problem above.
The technical solution of the present invention is as follows: wear-resisting welding wire with flux core, medicinal powder constituent mass percentage are as follows: silicomangan 20~
