INTRODUCTION
GTAW
Gas Tungsten Arc Welding
TIG
Tungsten Inert Gas
Las Argon
Proses pengelasan yang memanfaatkan panas dari arc (busur api) yang tercipta antara
ujung non consummable electrode (tungsten) dan workpiece.
Inert gas digunakan sebagai shielding gas yang melindungi arc terhadap kontaminasi
udara sekitarnya.
Umumnya filler rod digunakan sebagai matrial pengisi dan diumpan secara manual ke
welding pool, beberapa aplikasi tidak menggunakan filler.

PRINCIPLE OF OPERATION
1. Memanfaatkan panas dari arc
antara non consumable
tungsten electrode dan base
metal
2. Kawat pengisi (filler metal)
tidak digunakan pada matrial
tipis
3. Filler metal tidak ditrasfer
melalui arc melainkan mencair
karenanya
4. Arc dilindungi oleh inert gas
yang mengalir melalui ceramic
nozle
5. Hasil pengelasan halus dan
hanya memerlukan sedikit
finishing
