Joining processes

  • Common joining processes:
    • Welding - melting and fusing metal pieces together using heat.
    • Soldering - joining metal pieces using a lower melting point filler metal.
    • Adhesive bonding - using adhesives or glue to bond metal components together.
    • Brazing - joining metal components by melting a filler metal with a lower melting point.

  • Casting processes involve pouring molten metal into a mould and allowing it to solidify.
    • Casting is used to create a desired shape.

Casting processes

  • Common casting processes include:
    • Sand casting - using a mould made of sand to create complex metal shapes.
    • Die casting - pouring molten metal into a reusable mould under high pressure.
    • Investment casting - creating detailed metal parts by using wax patterns and ceramic moulds.

Heat treatment processes

  • Common heat treatment processes include:
    • Annealing - heating metal to a specific temperature and then cooling it to soften or relieve internal stresses.
    • Quenching - rapidly cooling metal from a high temperature to increase its hardness or strength.
    • Tempering - reheating quenched metal to a specific temperature and then cooling it to improve its toughness.
