3
Types of Welding
  • Ultrasonic
  • Hot Gas
  • Spin (Friction)
  • Adhesive

4
Adhesive Process
  • Adhesive Applied
  • The Parts are Joined
  • Bond hardens

5
Types of Thermoplastic Bonding
  • Monomer Cements
  • Solvent Cements

6
Types of Thermoplastic Adhesives
  • Cellulose Acetate
  • Cellulose Acetate Butyrate
  • Cellulose Nitrate
  • Polyvinyl Acetate
  • Polyamide
  • Acrylic

7
Types of Thermosetting Bonding
  • Catalyze Bonding
  • Flexible Sheets

8
Types of Thermosetting Adhesives
  • Cyanoacrylate
  • Polyester Isocyanate
  • Urea Formaldehyde
  • Melamine Formaldehyde

  • Tongue and Groove
  • V Joint
  • Lap Joint
  • Align Dependant
  • Butt Joint
  • Beveled Joint
  • Other Joints
  • Multiple Tongue and Groove
  • Tenon Joint

10
Self Aligning Joints
  • Tongue and Groove
  • V Joint
  • Lap Joint

11
Align Dependant Joints
  • Butt Joint
  • Beveled Joints

12
Other Joint Considerations
  • Multiple Tongue and Groove
  • Tenon Joint

13
Special Considerations
