A certain degree of abrasion and corrosion occurs, surface working size is changed, and the normal work of internal combustion engine is influenced whether when serious
Make.Therefore need timely to change the air inlet valve and air outlet valve of internal combustion engine of abrasion, but replacement cost is higher, discarded internal combustion engine
Air inlet and exhaust valve is not also recycled timely, causes the serious wasting of resources.
The content of the invention
In order to solve deficiency of the prior art, the present invention proposes a kind of air inlet valve and air outlet valve of internal combustion engine continuous casting casting rod and its weldering
Connect technique.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of air inlet valve and air outlet valve of internal combustion engine continuous casting casting rod, include the component of following mass percent：
A kind of welding procedure of air inlet valve and air outlet valve of internal combustion engine continuous casting casting rod, the processing step are：It is carbonized using oxy-acetylene
Flame overlaying method or tungsten argon arc soldering method carry out built-up welding to workpiece.
The pre-heat treatment should be carried out before the welding, is preheating to 320 DEG C, 280 DEG C of built-up welding interlayer temperature.
Workpiece heap postwelding should carry out hidden lino removal immediately.
The beneficial effects of the invention are as follows：The present invention by special component by means of technique for overlaying, so as to be welded on internal combustion engine
The abrasion of air inlet and exhaust valve, the position of corrosion, realize the reparation of size, meanwhile, it is capable to further improve air inlet valve and air outlet valve of internal combustion engine
Corrosion resistance, wearability, extend the service life of air inlet valve and air outlet valve of internal combustion engine.The present invention suitably reduces phosphorus content, adds
More nickel, so as to improve the toughness of overlay cladding and comprehensive mechanical performance, in terms of corrosion resisting property, then excellent property is presented
Energy.
