__________ metal is a metal similar in composition to the metal being joined. It strengthens the
weld by filling the gap created between the two pieces of metal during welding. filler
What is the primary purpose of welding?
To join two or more materials together by melting and fusing them.
What does MSSC stand for in the context of welding?
Manufacturing Skill Standards Council.
What is the difference between MIG and TIG welding?
MIG welding uses a continuous wire feed as an electrode, while TIG welding uses a non-
consumable tungsten electrode.
Which gas is commonly used in MIG welding to protect the weld from contamination?
Argon or a mixture of argon and carbon dioxide.
What is the main advantage of using TIG welding?
It provides greater control and produces high-quality, clean welds.
In welding, what does the term “heat affected zone” refer to?
1
, The area of the base metal that has had its microstructure altered by the heat of welding.
What type of welding is often used for joining thin sections of stainless steel?
TIG welding.
What safety equipment is essential when performing welding operations?
Welding helmet, gloves, and protective clothing.
Which welding process is typically faster, MIG or TIG?
MIG welding.
What is the significance of the welding symbol on a blueprint?
It provides essential information about the type and size of weld required.
What type of welding is best for heavy steel structures?
Shielded Metal Arc Welding (SMAW).
What is the function of a filler material in welding?
To provide additional material to fill the joint between the workpieces.
