Q:

Carbon steels can be fusion welded.

A) True B) False
 
Answer & Explanation Answer: B) False

Explanation: Carbon steels are best treated using forge welding, resistance welding, arc welding or by gas welding. Carbon steels essentially cannot be fusion welded, because, of the occurrence of cracks which may cause due to carbon pick up.

Q:

Low carbon steels need not be preheated before welding.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: Carbon steels which contain carbon in a very low amount are not compulsorily required to be preheated before undergoing welding if the large runs are made. This is because, in low carbon steels, unlike high carbon steels, there is no cracking seen on welding.

Q:

What is the temperature needed for preheating in cast irons?

A) 550?C B) 600?C
C) 650?C D) 700?C
 
Answer & Explanation Answer: B) 600?C

Explanation: Cast irons, upon the removal of welding heat, get solidified very quickly. This solidification takes place due to the surrounding cold mass and the air around. Because of such quick cooling, the carbon gets retained and hard metal stays in the weld. To overcome this, cast irons have to be preheated to 600?C.

Q:

Which of the following is not a material used for making an electrode in metal arc welding, for treating stainless steels?

A) Niobium B) Columbium
C) Titanium D) Potassium
 
Answer & Explanation Answer: D) Potassium

Explanation: Stainless steels are best welded using the electric butt welding method and then followed by annealing at around 750?C to 800?C. Stainless steels can also be welded using the metal arc welding methods. For this the electrode which is needed is made up of niobium, titanium and columbium. These materials avoid the occurrence of the defect called weld decay.

Q:

Stainless steels are annealed at what temperature?

A) 650?C ? 700?C B) 700?C ? 750?C
C) 750?C ? 800?C D) 800?C ? 850?C
 
Answer & Explanation Answer: C) 750?C ? 800?C

Explanation: Stainless steels are hardened by constant heating and cooling and the best method suited for this alloy is electric butt welding. As soon as the stainless steel alloy is electric butt welded, it needs to be annealed at a temperature in between 750?C to 800?C.
