**Adhering- Gluing**
**Fusing (welding)**
New cards
12
Permanent
\ Methods used to permanently bond or join materials together, creating a strong and lasting connection.
e.g. Welding, Brazing, Soldering (joining metals by melting a filler metal), Pop riveting

**Adhering- Gluing**
once formed, cannot easily be separated
New cards
14
**Fusing (welding)**
Permanent process involving the heating of the surfaces such as metals and plastics. This process isn’t recommended when considering design for disassembly
New cards
15
Temporary
(non-permanent fastening)
Fastening or joining materials mechanically through the use of screws, rivets, bolts, pins, clips, nails, press studs and snaps.

Adv and Disadvantages of permanent vs temporary
Temporary:
ease for disassembly at the expense of permanent damage to the materials used eg. installing screws
Adjustability: Temporary joining methods offer flexibility in terms of adjustment and alignment of the joined parts.
\ Permanent:
Strength and durability: Permanent joining techniques, such as welding or adhesive bonding, can create strong and durable connections between materials.
Seamless appearance
Load distribution: Permanent joining techniques distribute the load across the entire joint, minimizing stress concentration.
