1. What is the process of project execution activity?

• Performing the activitiesneeded to meet the project
• Obtaining and manage quotations, bids and proposals as needed.
• Managing the projectteam and manage other resources.
• Collecting and analyse performance data.
• Generating projectdata for status reports and forecasts.
• Managing risks.

2. What are the types of joining processes?

Joining processes include welding, brazing, soldering, mechanical fas- tening, and adhesive bonding. Mechanical fastening can be used to provide either temporary or permanent joints, while adhesive bonding, welding, brazing, and soldering processes are mainly used to provide per- manent joints.

3. What is Resistance Welding & its application in the automotive sector?

Resistance Spot Welding (often just called spot welding) is a cost-effective joining technology that continues to be very popular in the automotive industry where high reproducibility and automation are essential criteria. ... Resistance Spot Welding is a pressure welding process.

4. What is fusion welding & types of fusion welding with its application in the automotive sector?

Each comes into contact with one of the pieces being welded. The two pieces of metal are then pressed together between the electrodes and an electric current is run through them. ... Resistance welding is a very prevalent form of fusion welding. It is used in the manufacturing of automobiles and construction equipment.

5. What is the 3-2-1 principle?

The 3-2-1 principle states that the six locators are sufficient to restrict the required degree of freedom of any work piece. In this, motion is restricted using clamps and locators. A three pin base can restrict five motions and six pins restrict nine motions.

6. Define Body coordinate system?

A constant rotation about an axis written in the Body system is made up of the three rotations. The origin of the body coordinate system will be at the centre of mass. ... The axes of the body coordinate system will be the principal axes of the object. These axes are rotating with the object.

7. Elaborate Body plane system & its essentials.
