What is welding used for, and how does it work?
Welding joins metals by heating them to a high temperature, melting the edges, and fusing them together, often using a filler material. Common in construction, automotive, and metal fabrication.
What are the advantages of soldering?
Soldering is used for joining electrical components and small metal parts. It is low-temperature, preserves delicate components, and allows for rework if needed.
What is brazing, and how does it differ from welding?
Brazing joins metals by melting a filler material at a lower temperature than welding. It is less strong than welding but suitable for thin materials or dissimilar metals.
What types of adhesives are commonly used in manufacturing?
- Epoxy: High strength, bonds a variety of materials.
- PVA (Polyvinyl Acetate): Used for wood.
- Cyanoacrylate (Super Glue): Fast-setting, ideal for small repairs.
- Contact Adhesive: Bonds large surfaces like laminate and plastics.
What is riveting, and where is it used?
Riveting is a permanent mechanical joining method where a rivet is inserted through aligned holes and deformed to hold parts together. Common in aircraft, bridges, and metal structures.
Explain the process of using screws for joining.
Screws create a temporary or semi-permanent join by cutting threads into materials (wood, plastic, or metal). They allow for disassembly and maintenance.
What is the purpose of a dowel joint in woodwork?
A dowel joint uses wooden or metal dowels inserted into aligned holes for added strength in furniture making. It ensures precise alignment and strong connections.
How does bolting differ from screwing?
Bolting typically requires a nut and washer to secure parts, creating a stronger join than screws. It is often used in construction and mechanical assemblies.
What are the benefits of using snap-fit joints in plastic products?
Snap-fit joints allow for quick, tool-free assembly and disassembly. They are cost-effective and commonly used in consumer electronics and packaging.
What is a mortise and tenon joint?
A strong wood joint where a tenon (protrusion) fits into a mortise (hole or slot). It is widely used in traditional furniture and construction.
