what is solidworks ? SolidWorks is a popular 3D computer-aided design (CAD) software that is used for creating and designing complex models and assemblies in mechanical engineering, product design, and other industries. It is developed by Dassault Systèmes, a French software company that also owns other popular software such as CATIA and SIMULIA. SolidWorks provides a range of tools and features for creating 3D models, such as sketching, surface modeling, solid modeling, sheet metal design, and assembly modeling. It allows users to simulate and analyze the performance of their designs before manufacturing, including motion analysis, finite element analysis (FEA), and computational fluid dynamics (CFD). It also supports collaboration and sharing of designs with other users through various formats such as STEP, IGES, and STL. SolidWorks is known for its user-friendly interface and intuitive design, which makes it easy for beginners to learn and use. It is widely used in industries such a
Welding :
Types of flame :
The different of flame can be produced by varrying the oxygen , acceteteyne ratio .
1. Neutral flame
2. Oxidizing flame
3. Carburizing flame
Neutral Flame :
- The ratio of oxygen and aceteyne is equal to 1:1 .
- The inner core will be yellow or red and outer cone will be light blue colour .
- The maximum temperature of neutral flame is 3100° that is inner core .
- Outer core temperature is 1275° .
- N is the size of inner core .
Oxydizing Flame :
- The ratio of oxygen and acetelyne is equal to 1.15 to 1.5 that is greater than 1
- The maximum temperature of oxydizing Flame is 3300 ° that is inner core.
- Outer temperature is 1350 °.
- In oxidizing flame exess amount of oxygen is present .
- Size of inner core is N/3 to N/2 .
- Oxydizing Flame is used to joining of high reactivd metals.like AL , Mg .
Carburizing Flame :
- The ratio of oxygen and acetelyne is equal to 0.85 to 0.95 that is less than 1 .
- The maximum temperature of carburizing flame is 2900 ° that is inner core .
- Outer core temperature is 1150° .
- The size of inner core is 2N to 3N.
- Because of short supply of oxygen the flame has to travel for a long distance .
- Carburizing flame is used to joining of high carbon steels , copper alloy and nickel .
