WELDING IT IS A PROCESS OF JOINING TWO OR MORE SIMILAR OR DISSIMILAR METALS WITH OR WITHOUT APPLICATION OF HEAT, WITH OR WITHOUT APPLICATION OF PRESSURE, WITH OR NITHOUT APPLICATION OF MATERIAL. WELDING IS SIMPLE, EASY,FAST AND REDUCES OVERALL PRODUCTION COST IN MANY WAYS IT IS SUPERIOR TO BOTH CASTING AND FORGING
TOP 5 ADVANTAGES OF WELDING 1.It provides a permanent joint.The welded parts becomes a single entity 2.Welding has replaced riveting because of being faster and noiseless.It gives a stronger and leakproof joint. 3.Welding joint can be stronger than the parent materials if a filler metal is used that has strength properties superior to those of the parents,and if proper welding techniques are used. 4 Welding is usually the most economical way to join components in terms of material usage and fabrication costs.Other mechanical assembly (rivets and bolts)is usually heavier than a corresponding weldament 5.The alterations and addition to the existing structure is easy. And since there are no extra plates added(like riveting),so it keeps the structure light.
TOP3 DISADVANTAGES OF WELDING 1.Most welding techniques are inherently dangerous because they involve the use of high energy. 2.weldingjoints are more brittle and therefore their fatigue strength is less than the members joined. 3.The inspection of welding work is more difficult and costlier than the riveting work because the defects like internal air pockets and slag inclusion are difficult to detect. e e o
