B.
O Cast iron, mild steel, aluminium, copper
C.
O Copper, cast iron, mild steel, aluminium
D.

Answer 1

Question :-

The correct sequence of the given materials in ascending order of their weldability is:

A. Mild steel, copper, cast iron, aluminium.

B. Cast iron, mild steel, aluminium, copper.

C. Copper, cast iron, mild steel, aluminium.

D. Aluminium, copper, cast iron, mild steel.

Answer :-

• Aluminum < copper < cast iron < Mild steel.

Explanation :-

• The easy with which welding of a give material can be done without producing any defect is called weldability .
• Weldability is considered as ease of accomplishing a satisfactory weld joint and can be in determined from quality of the weld joint, effort and cost required for developing the weld joint.

Extra :- The weldability of some more metals in ascending order is :- Stainless steel < Low alloy steel < Cast iron < Steel < Iron.

{ Low carbon steel = Good weld ability.

High carbon steel = Poor weldabilily. }
