Study Notes
Advanced Joining Processes
- The presentation covers various advanced joining processes, focusing on joining by forming.
- Types of joining include: force-closed joining, form-closed joining, and material-closed joining.
Joining by Forming
- This method involves applying pressure or force to create a connection between materials without melting
- Three main types of joining by forming are discussed: force-closed, form-closed, and material-closed
- Force closed joining relies on interference pressure and applies pressure to one tube, causing expansion and contact with another tube
Forming Mechanisms - Force-Closed Joining
- The tubes are precisely positioned.
- Pressure is applied to one tube, causing it to expand, and create contact with the other.
- Both tubes slightly deform.
- This technique creates a strong durable joint due to residual stresses.
Forming Mechanisms - Form-Closed Joining
- This technique involves an interlocking design between parts, often involving grooves, threads, or knurls.
- These components have specific shapes which interlock and are formed to achieve a durable bond.
- The design is a critical factor in determining the strength and durability of the joint.
Forming Mechanisms - Material-Closed Joining
- Two materials are joined under high pressure and velocity.
- The materials deform plastically, forging a metallurgical bond.
- Methods include: magnetic pulses, explosion welding, and high-velocity impacts.
Mechanical Joining by Forming
- Main categories include tubular and planar components.
- Joining methods explained using various visuals (diagrams).
Advantages and Disadvantages of Joining Methods
- Different joining methods (force-closed, form-closed, material-closed, rolling, hydroforming, crimping, electromagnetic forming, plastic instability) have different advantages and disadvantages.
- Factors include materials compatibility for joining, equipment costs, complexity, process controls, durability.
