1 . Description :

Precision alloys include soft magnetic alloys and expansion alloys which have special physical and mechanical properties, and are extensively applied in the key elements and devices of precision motor, electric appliance, instruments and meters, telecommunications equipment.

Invar36 use oxyacetylene welding, electric arc welding, welding and other welding methods. Since the coefficient of expansion and chemical composition of the alloy is related should be avoided due to welding causes a change in the alloy composition, it is preferable to use Argon arc welding welding filler metals preferably contains 0.5% to 1.5% titanium, in order to reduce weld porosity and crack.
