TIG advantages - ✔️✔️welds more metals and metal alloys than any other process,
high quality and precision, pin point control, aesthetic weld beads, no spark or spatter,
no flux or slag, no smoke or fumes
why is aluminum so widely used in industry today. what are some of its desirable
properties. - ✔️✔️so abundant, light, strong. low density, light weight, high strength,
superior malleability, easy to machine, good corrosion resistance, good thermal and
electrical conductivity
threads into the head of the torch and aligns the tungsten in the gas cup - ✔️✔️collet
body
inserts into the collet body and secures the tungsten electrode by threading and
tightening the back cap - ✔️✔️collet
attached to the collet body, either threaded or held in place by friction fit. directs
shielding gas to the weld area - ✔️✔️nozzel
what does GTAW stand for - ✔️✔️Gas tungsten arc welding
TIG disadvantages - ✔️✔️lower filler metal deposition rates, good hand eye
coordination, brighter UV rays then other processes, slower travel speeds then other
processes, equipment costs tend to be higher
how do you strike an arc for TIG/ how hot is the arc - ✔️✔️use the foot peddle /
11,000* F
why does TIG not require flux - ✔️✔️it has shielding gas
TIG safety concerns - ✔️✔️UV rays bad for your eyes
secures tungsten by threading into torch head and tightening the collet against the collet
body - ✔️✔️back cap
common TIG shielding gases and pressure. how is it measured. what would helium be
used as a shielding gas for - ✔️✔️Argon, carbon dioxide, helium, oxygen. 15-20CFH.
