Row protection, prevents welding position from aoxidizing.The oxygen that screw tap head and screw tap bar are run into after heating up in air during due to welding is easy
Aoxidize, welding rear oxidation layer is merged together with weld tabs in welding position, and impurity is formed in welding position, causes welding strong
Degree declines.Oxidation just forms nitrogen blanket after heating starts around welding portion, dispels the air of surrounding,
Prevent the generation of oxidation so that welding position is more uniformly distributed.Simultaneously as the product temperature after welding is very high, Temperature fall
Process it is slower, also easily aoxidize, using air gun by nitrogen jet to welding position improve cooling rate, protect weld part
Position, the generation of oxidation reaction is reduced, improve welding efficiency and weld strength.In addition, nitrogen jet is carried out using air gun so that spray
The nitrogen gone out has certain speed, it may also be used for the cleaning of screw tap head and screw tap bar before and after welding, removes attached to it
Impurity and residual.
Above-mentioned embodiment is the preferred case of the present invention, is not intended to limit protection scope of the present invention.
