Chapter 29, Problem 1RQ
To determine
Name the principal groups of processes included in fusion welding.
Expert Solution & Answer
Explanation of Solution
The principal groups of processes included in fusion welding are listed below:
- 1. Arc welding: In this welding process, joining of two workpieces is accomplished by the heat produced by an electric arc between an electrode and the workpiece.
- 2. Resistance welding: This welding process uses the combination of both heat and pressure to achieve coalescence of two metal parts.
- 3. Oxyfuel gas welding: This welding process accomplished by a high temperature flame, which is produced by the reaction of various fuels with oxygen.
- 4. Other fusion welding: The fusion welding processes which are comes under “other” category are given below:
-
- Electron beam welding: In this process, heat used for welding is produced by hitting high-intensity and highly focused steam of electrons against the surface of the work metals.
- Laser beam welding: In this process, heat used for welding is produced by hitting highly concentrated and focused coherent light beam against the surface of the work metals.
- Thermit welding: In this process, heat used for welding is produced from the chemical reaction of thermit.

Question 1
The engine of a 3500-N car is generating a constant power of 50 hp (horsepower)
while the car is traveling up the slope with a constant speed. If the engine is
operating with an efficiency of € 0.8, determine the speed of the car. Neglect
drag and rolling resistance. Use g 9.81 m/s² and 1 hp = 745.7 W.
