FILLER METAL
REMARKS
2Cr-2Fe-2Mo
Not recommended for
welding, because
brittle when cooled.
8Mn
Not recommended for
welding.
3A1-l3V-llCr
3A1-13V-llCr
Can be satisfactorily welded
using inert-gas-shielded
tungsten arc without filler
or with consumable filler
electrode. Also, it can be
seam and spot welded.
6A1-4V
6A1-4V AMS4954,
Weldments have lower ductility
3A1, or commercially
than parent metal, however,
pure AMS4951
useful fusion and resistant
welds can be made with proper
precautions. Complete inert
gas shielded required for
either tungsten arc or
consumable electrode fusion
welds. Resistance welding
is accomplished by technique
similar to those used for
austenitic stainless
7A1-4Mo
See 6A1-4Mo.
8A1-IMo-lV
Only limited data available.
Fusion and resistance welding
of sheet accomplished ping
technique common to other
titanium alloys. Stress relief
recommended after welding.
