Welding Test Questions And Answers 100%
Pass.
Name three principle types of welding. - Answer✔Gas welding, electric arc welding, and electric
resistance welding.
What are some advantages of gas shielded arc welding? - Answer✔The weld is stronger, more
ductile, and more corrosion resistant.
Which method of welding is less likely to cause buckling or warping of thin metal sheets? -
Answer✔Electric arc (or TIG) welding.
What is the purpose of shielding an arc weld with and inert gas? - Answer✔The gas prevents
atmospheric oxygen and/or nitrogen from contaminating the weld.
What is a common method of controlling expansion when welding a joint? - Answer✔Place tack
welds along the length of the joint.
What is the effect of inadequate penetration on a weld? - Answer✔The weld will be weak.
What is the purpose of the flux used with brazing and silver soldering? - Answer✔The flux
cleans the base metal by removing any oxide film.
What type of flame is used when torch brazing or silver soldering? - Answer✔A neutral flame.
What must be done to soldering iron tip to increase the amount of heat transferred from the tip to
the work? - Answer✔The tip must be clean of all contaminates and properly tinned.
What is the preferred for welding aluminum? - Answer✔Tungsten Inert Gas (TIG)welding.
What is the preferred method of welding magnesium? - Answer✔Tungsten Inert Gas
(TIG)welding.
What precautions must be observed in order to weld titanium? - Answer✔All traces of oxygen
and nitrogen must be kept away from the weld area.
Describe one type of repair that could be made to a dented steel tube cluster joint? - Answer✔A
formed steel patch plate could be welded over the damaged area.
How can a soft flame be obtained without reducing the heat output of the torch? - Answer✔Use a
larger tip and adjust the gas pressure accordingly.
What factors determine the amount of heat delivered by a gas welding torch? - Answer✔The size
of the torch tip and gas pressure.
