Welding & types of welding

 Welding :

Welding is the process of joint which are joint two or more parts are joint by fusion of metal or nonmetal process by the heat and allowing cooling so formed that joint is known as welding process.

there are two types of welding 

1. Solid types  welding :

  Forging welding   : In this welding process metal are pressurized (without melting) and produce the heat between the metal joints by friction process that types of joint is called solid state welding .

2.Fusion type welding  :

In this welding process , metal to metal fusion (with melting ) are melt so molecule of atom are charged and start motion to other metal pieces so formed the joint is called fusion welding process.

Continuity equation & types of flow |FLUID MECHANICS ||PART -4

Image
Basic terminology of fluid mechanics  Steady flow : In this flow velocity of fluid particle don't change with time at fixed point of fluid is called steady flow. Unsteady flow: In this flow velocity of particle change with time at fixed point of fluid is called unsteady fluid . Uniform flow : In this flow the magnitude of flow don't change (same ) at point of fluid . Non-uniform flow: In this flow the magnitude of flow  change (different) at point of fluid . Laminar flow :   In this flow fluid particle move in smooth and regular in motion is called laminar fluid is called laminar fluid and it is also  called steam line flow . Turbulent flow :   In this flow fluid particle move in randomly  and irregular  in motion is called laminar fluid is called laminar fluid. Continuity equation : According to this law the inlet fluid is equal to outlet fluid this law based on the conservation of mass . Q = p.A.V   Where the Q is discharge of fluid and p is...

CASE STUDY at ZOMATO

Image
Case study at zomato :   Zomato initially named as Foodiebay was started in 2008 by Mr. Deepinder Goyal. It is a restaurant searching platform providing in-depth details with autonomous reviews and ratings. Foodiebay, the initial name was changed to Zomato in November 2010 to increase their reach among people. To differentiate themselves from their competitors, Zomato concentrated on adding approx. 18,000 new places to eat from. Along with they also decorated many special features, such as pointed to particular dishes or opening times”. To be the largest resource in food supply market, Zomato bought urbanspoon, a leading restaurant service providing portal for $52 million to enter US, Canada and Australia to leverage local insights and experience and to expand their business in overseas seeing the future goal and objective.   To expand to more 50 countries Milestones: Number of listed restaurants: in 2008 it was 4000 restaurants which increase to 94000 in 2013 and current...

Interview questions for mechanical engineering

Q.  What is elasticity?  Ans. It is the propertyof material where apply deforming force on the body  so body is deformed,  it will regain its original shape after removing deforming force.  Q. What is plasticity?  Ans. It is the property of material where apply deforming force on the body so it will permanently deformed after removing deforming force.  Q. What's brittleness?  Ans. It is the property which is distortion  of material when applying impact load  or it will break in small parts.  Compressive strengh is high and tensile strength is low.  Q. What is creep?  Ans. It is the property of material which have slow permanent deformation  within temperature along long time.  It's occure in belt  Q. What's toughness?  Ans.is the property of material,Which is resist the high impact load for short time. That is callled toughness.  Q. What's Malleability  ??  Ans.  It the property of m...
