Question

Advantage disadvantage application of resistance welding

Answer 1

Resistance Welding : Principle, Types, Application,Advantages and Disadvantages. ... It is named as resistance weldingbecause it uses electricresistance to produce heat. It is a very efficient pollution free welding process but itsapplications are limited due to its high equipment cost and limited material thickness.

Answer 2

Advantages and disadvantages of resistance welding

Advantages of resistance welding are the following below :
It is very economical process because there are no consumables used in this process.Heating of the work piece is confined to a very small part so less distortion.Very little skill is required to operation resistance welding machine.By this process also weld dissimilar metal as well as metal plate of different thickness.Suited for mass production as they give a high production rate.Welding speed is very high.

Disadvantages of resistance welding :

Resistance welding machine are highly expensive.Lower tensile and fatigue strength.It is limited only to lab joints.Limit of sheet metal thickness is less than 3 mm.
