Want to know about Riveted Joints?
Then you landed on the right place, Here you will get complete information, from scratch to end.
So, Come and stay with me while I start the engine of this knowledgeable journey on Engineers Rail.
So, Without further delay, let’s dive in from the basics to advanced-
Definition of Riveted Joints-
Riveted joints are those that can not weld or join by any means other than using rivets causing permanent joints of two separated components, known as Rivets Joints.
This can be the basic definition of Rivet joints, now let’s move to the types of rivets joints. So, Here we go-
Types of Riveted Joints-
Mainly Two types of riveting joints are used while riveting any metal sheets-
(I) Lap Joint Rivet
(II) Butt Joint Rivet
Lap Joint Rivet-
Lap joint rivet is done by Overlapping metal sheets from the corner side.
When a Single straight line of rivets is used in the lap joint, then it is called a Single row lap joint.
When a Double straight line is used to join two metal sheet corners in a lap joint, Known as a Double-row lap joint.
When a Double line of rivets is placed in the zig-zag dimension, then it is called a Double-row zig-zag lap joint.
Butt Joint Rivet-
When two metal sheet joints side by side together facing in the same direction, Knowm as Butt Joint.
When the jointing side of metal sheets comes together, then riveting is done by placing a piece of the sheet above the metal sheet.
This piece of sheet is known as Strap.
If a Single strap is used in butt riveting, then it is called a Single strap butt joint.
And, When a Double strip is used to riveting the butt joint, then it is called a Double strap butt joint.
When the single row of rivets and the single strap is used on both metal sheets i butt joint, then it is known as single-row single strap butt joint.
When the single row of rivets and two-strap is used on both metal sheets to fastening the butt joint, then it is known as the Single row double strap butt joint.
And, when two rows of rivets and the double strap is used on both metal sheets of butt joint, then it is called Double row double strap butt joint.
In special cases, Triple-riveted joints are used in both types of joints.

Failure of Riveted joint-
Here are some types of failure in riveted joints, This will help you to understand the possible cause of riveted joint failure.
- Bearing failure
- Net-tension failure
- shear-out failure
- Cleavage Failure
- Cleavage-tension failure
- Bolt Failure
- Fastener Failure
- Pull-through Failure
Above mentioned reasons are the main sources of Riveted joint failure.
Now, I am going to discuss the equation of Efficiency of the Riveted joint, So, it will be easy to calculate efficiency, If needed.
Efficiency of RIveted joint-
Here is the general equation for calculating the efficiency of the riveting joints.
Advantages of Riveted Joint-
Here are some advantages of the rivet joints-
- Used for metal and non-metal materials
- Enhance production rate
- Heavy duty
- Easy maintenance
- Quick Inspection
Disadvantages of Riveted Joint-
Here are some Disadvantages of the rivet joints-
- Reduction of Plate strength due to multiple holes.
- High labour cost
- High cost of materials in use
- Lack of grip
- Non-leak Proof
- Increase of weight due to strap and rivets
Applications of Riveted Joint-
Here are some applications and riveted joints uses-
- Structural Work
- Power Plants
- Aero Engineering
- For Vibration Reduction
Let’s have a look at this comparison-
Difference between welded joints and Riveted joints-
Here are some major differences of welded and riveted joints, Comparing side by side-
|Welded Joint||Riveted Joint|
|No holes are required to drill on the parent components in order to join them by welding||Riveting require a number of through holes in a specific location|
|The load capacity of the components before and after welding remains more or less the same||Due to the presence of holes on the components, effective area reduces, and thus load carrying capacity is also decrease after riveting|
|Many welding processes tend to change the metallurgical properties of the base plate surrounding the weld bead||Metallurgical properties of the base plate material remain unaffected in riveting|
|strength of the welded joint is very high, often it is more than the strength of base plates||The strength of the riveted joint is comparatively low|
That’s it for now, You gained knowledge of Riveted Joints and their types and the next failure reasons of rivet joints and thereafter, you knew the formula for efficiency calculation and next advantages, disadvantages and applications of riveted joints.
