In the last session, we had discussed gas welding process and arc welding process and whereas in today's session, we will discuss on Resistance Spot Welding along with its Definition, Construction, Working Principle, Applications, Defects, Advantages, and Disadvantages. Definition of Resistance Spot Welding:The heat required for melting and joining of the plates obtained through the Scrubbers:The Major Types of Industrial ScrubbersThis sorbent can be mixed with the acid gas in two ways. There are two different types of dry industrial scrubbers. The first is called dry sorbent injection. During this process, the gas is mixed directly with the alkaline sorbent. The second method is the spray dryer absorbent method. In this method, the contaminated gas is processed through
Advantages of Explosive Welding . Large surfaces may be welded; High quality bonding:high strength, no distortions, no porosity, no change of the metal microstructure; Low cost and simple process; Surface preparation is not required. Disadvantages of Explosive Welding:Brittle materials (low ductility and low impact toughness) cannot be processed; Types of Heat Exchangers Shell and tube, Plate typeJun 30, 2019 · As in all mechanical devices, each type has its advantages and disadvantages. Types of heat exchangers Shell and tube type. The most basic and the most common type of heat exchanger construction is the shell and tube type. This type of heat exchanger consists of a set of tubes in a container called a shell. Welding and Metal Fabrication
