Understanding TIG Welding

What does TIG stand for in TIG welding?

• Titanium Integrated Gas

• Tungsten Inert Gas

• Titanium Inert Gas

• Tungsten Integrated Gas

Which gas is typically used in TIG welding?

• Oxygen

• Argon

• Hydrogen

• Nitrogen

What is the main advantage of using a TIG welder for aluminum and chrome-moly steel?

• Faster welding process

• No need for filler material

• Higher quality and precision welds

• Cheaper than other welding methods

What type of electrode does TIG welding use?

• Consumable tungsten electrode

• Non-consumable carbon electrode

• Non-consumable tungsten electrode

• Consumable carbon electrode

What is the purpose of the inert gas in TIG welding?

• To create a hotter flame

• To make the weld more brittle

• To protect and cool the tungsten and weld puddle

• To increase the welding speed

Which of the following is NOT a control feature of a TIG machine?

• Variable amperage control

• Balance control

• Pulsed mode

• Flame size adjustment

What is the recommended gas flow rate for TIG welding?

• 5-10 cubic feet per hour

• 10-15 cubic feet per hour

• 15-20 cubic feet per hour

• 20-25 cubic feet per hour

What is a common filler rod for welding aluminum?

• 4043 alloy

• 5356 alloy

• 6013 alloy

• Both 4043 and 5356 alloys

Why is it important to control the heat when TIG welding alloy steels?

• To speed up the welding process

• To make the weld more flexible

• To reduce the need for filler material

• To prevent thermal shock

What should you do if the tungsten electrode touches the workpiece?

• Continue welding

• Stop welding and clean the tungsten

• Increase the gas flow

• Replace the workpiece
