What does TIG stand for in welding?
Analysis & Theory
TIG stands for **Tungsten Inert Gas** welding, using a tungsten electrode.
Which of the following is used as an electrode in TIG welding?
Analysis & Theory
TIG welding uses a **non-consumable tungsten electrode**.
In MIG welding, the electrode is:
C
A continuously fed wire
Analysis & Theory
**MIG welding** uses a **consumable wire electrode** that is fed continuously into the weld pool.
Which inert gas is commonly used in both TIG and MIG welding?
Analysis & Theory
**Argon** is commonly used as a shielding gas in both TIG and MIG welding.
Which process is more suitable for welding thin metals with high precision?
Analysis & Theory
**TIG welding** provides better control, making it ideal for **thin and delicate metals.**
Which welding process is faster and more suitable for mass production?
Analysis & Theory
**MIG welding** is **faster** and preferred in **industrial and mass production environments.**
Which welding technique generally requires more operator skill?
Analysis & Theory
**TIG welding** requires **high skill and steady hands** for quality welds.
Which of the following is a disadvantage of TIG welding?
C
Slow process and higher cost
D
Cannot weld stainless steel
Analysis & Theory
TIG welding is **slower and more costly**, though it produces high-quality welds.
MIG welding is best suited for:
A
Outdoor windy conditions
B
High precision aerospace parts
C
High-speed welding of thick metals
Analysis & Theory
**MIG welding** is used for **fast welding of thick metals**, often in fabrication and manufacturing.
Which welding process uses a non-consumable electrode?
Analysis & Theory
**TIG welding** uses a **non-consumable tungsten electrode**.
