List the five joint types used in welding.
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.

The heat rate is defined as, HR Qbioler Wnet where Qbioler is the heat transfer rate (Btu/h) to the water in the boiler due to the combustion of a fuel and Wnet is the net power (kW) delivered by the plant. In comparison, the thermal efficiency of the power plant is defined as, nth Wnet Qbioler where the numerator and denominator have the same units. Consider a power plant that is delivering 1000 MW of power while utilizing a heat transfer rate of 3570 MW at the boiler. Determine the heat rate and thermal efficiency of this power plant.arrow_forward
