List the five joint types used in welding.
Expert Solution & Answer
To determine
The five types of joints in welding.
Explanation of Solution
Welding joints are of five types:
- Butt joint
- Lap joint
- Tee joints
- Outline corner joint
- Edge joint
Butt joint:
It is a type of welding in which the edges are welded. This do not increase the width of the metal. It has flexibility of being welded from both sides. Edges of metal are kept parallel for welding.
Lap joint:
In this welding, edges of the metal are overlapped to perform the welding operations. A fillet weld is used for performing lap joint. Welds can be performed on either side of the metal pieces.
Tee joints:
In this welding, the surface of one metal is placed over the surface of other metal. The angle between the parts to be welded is right angle. This welding is done by fillet welding.
Outline corner joint:
In this welding, a piece of metal is brought in contact by making an angle of 90-degree. Corners of edged are put together for welding.
Edge joint:
Even edges of two metals are put together by side to perform welding. These joints can be welded from one side only.
Types of welding can be seen in given figure.

A piston–cylinder device contains 50 kg of water at 250 kPa and 25°C. The cross-sectional area of the piston is 0.1 m2. Heat is now transferred to the water, causing part of it to evaporate and expand. When the volume reaches 0.26 m3, the piston reaches a linear spring whose spring constant is 100 kN/m. More heat is transferred to the water until the piston rises 20 cm more.

Determine the work done during this process.
The work done during this process is kJ.
A 4-m × 5-m × 7-m room is heated by the radiator of a steam-heating system. The steam radiator transfers heat at a rate of 10,000 kJ/h, and a 100-W fan is used to distribute the warm air in the room. The rate of heat loss from the room is estimated to be about 5000 kJ/h. If the initial temperature of the room air is 10°C, determine how long it will take for the air temperature to rise to 25°C. Assume constant specific heats at room temperature. The gas constant of air is R = 0.287 kPa·m3/kg·K (Table A-1). Also, cv = 0.718 kJ/kg·K for air at room temperature (Table A-2).
Steam enters the radiator system through an inlet outside the room and leaves the system through an outlet on the same side of the room. The fan is labeled as W sub p w. The heat is given off by the whole system consisting of room, radiator and fan at the rate of 5000 kilojoules per hour.
