🔗What is the difference between Cold Riveting and Hot Riveting
Depending on the how riveted plates are placed, the riveting classified mainly into two i) Lap joint ii) Butt joint
Lap joint: In lap joint, plates overlapped each other. The rivets are inserted in the overlapped region.
Butt joint: In this type of riveting, the plates to be joined is kept in alignment butting/ touching, without forming an overlap. Another plate known as cover plate is placed over either one side or on both side of the main plates, then it is riveted with main plates.
Based on number of cover plates used, the butt joint again divided into two, Single strap butt joint and double strapped but joint.
Single strap butt joint: Type of but joint in which only one cover plate is placed on the main plate.
Double strapped but joint: Type of but joint which uses two cover plates. One cover plate is placed both sides of the main plates then riveted.
Based on how many rows of rivets in joint
Single riveted joint: The riveted joint has one row of the rivet in a lap joint or when there is only one row of the rivet on each plate of butt joint
Double riveted joint: Two rows of rivets are used in a lap joint or two rows of rivet are used in each main plate of but joint.
Similarly, there are triple riveted, quadruple riveted joints are there.
Based on the arrangement adjacent rows of rivet
Chain riveted: The rivets in the adjacent rows are opposite to each other (in same transverse line).
Zigzag riveted: When the rivets in adjacent rows are not in chain arrangement.
