What does TIG stand for in TIG welding?
Answer: Tungsten Inert Gas
TIG stands for Tungsten Inert Gas, a welding process that uses a non-consumable tungsten electrode and a separate filler rod, shielded by an inert gas.
What is the correct shade number for a welding lens when MIG welding at 200 amps?
Answer: Shade 10
AWS recommends shade 10 for MIG welding in the 150–250 amp range to protect the eyes from the intense arc light.
What type of weld symbol on a blueprint indicates a weld all around the joint?
Answer: A circle at the junction of the arrow and reference line
A small circle at the junction of the arrow line and reference line on a weld symbol means the weld is to be made all around the joint.
Which defect is caused by insufficient fusion between the weld metal and the base metal?
Answer: Incomplete fusion
Incomplete fusion occurs when the weld metal does not properly bond to the base metal or previous weld passes, creating a weak joint.
What is the function of flux in Stick (SMAW) welding electrodes?
Answer: To generate shielding gas and slag to protect the weld pool
The flux coating on SMAW electrodes burns during welding to create shielding gases and a protective slag layer that shields the molten weld pool from atmospheric contamination.
What is the minimum safe distance to store oxygen and acetylene cylinders apart when not in use?
Answer: 20 feet
OSHA requires oxygen and fuel gas cylinders to be stored at least 20 feet apart, or separated by a non-combustible barrier at least 5 feet high with a fire-resistance rating of at least 30 minutes.
