Title: Sheet Metal Working


1
Sheet Metal Working
  • Soldering and Riveting

2
Types of Sheet Metal
  • Steel (Ferrous)
  • Non-Steel (Non-Ferrous)

3
Steel Sheet Metal
  • Galvanized
  • Stainless
  • Tin Plate

4
Non-Steel Sheet Metal
  • Copper
  • Aluminum
  • Lead
  • Zinc

5
Galvanized Sheet Metal
  • Soft steel sheet covered with a zinc coating
  • Has a dull appearance

6
Galvanized contd.
  • Zinc coating provides a corrosive resistance
  • Relatively inexpensive

7
Galvanized contd.
  • Used for many purposes
  • Roofing
  • Ductwork
  • Gutters
  • Signs
  • Posts

8
Stainless Steel Sheet Metal
  • High grade steel covered with a coating of
    chromium and nickel
  • Has high corrosive properties
  • Cleans easily

9
Stainless Steel contd.
  • Has a silver/chrome appearance
  • Very tough to bend

10
Stainless Steel contd.
  • Will last forever
  • Very expensive
  • Used for many purposes
  • Food/dairy industry
  • Sinks
  • Tables
  • Grills
  • Utensils

11
Tin Plate Sheet Metal
  • Steel coated with pure tin
  • Once widely used for sinks, cans, food/dairy
    industry
  • Mainly replaced by stainless steel

12
Copper Sheet Metal
  • High corrosive resistance
  • Used mainly in roofs and gutters
  • Very expensive

13
Aluminum Sheet Metal
  • Used for
  • Gutters and spouts
  • Siding
  • Wheels and rims
  • Cans
  • Good corrosive resistance
  • Very light weight
  • Durable

14
Lead Sheet Metal
  • One of the oldest sheet metals
  • Used for thick tanks and radiation areas
  • X-ray proof

15
Soldering
  • The joining of two or more pieces of metal by
    using an alloy with a lower melting point than
    the pieces being joined

16
The Make-Up of Solder
  • Tin / Lead
  • Examples
  • 50/50
  • 60/40
  • 95/5
  • Lead Free Solder

17
The Make-Up of Solder contd.
  • As you increase the Tin , the melting point of
    the solder is lowered

18
Flux
  • Removes/Cleans the oxide film from the surface of
    metal
  • Solder would not stick without the use of flux
  • May come in many different forms

19
Types of Flux
  • Acid Flux
  • Hydro-chloric
  • Cut Acid
  • Rosin Flux
  • Powder
  • Paste
  • Liquid

20
Soldering Tools/Equipment
  • Solder
  • Electric Soldering Gun
  • Sal Ammoniac Block
  • Flux
  • Gas Bench Furnace
  • Propane Torch
  • Soldering Copper

21
Riveting Metal
  • Fastening device that is held in place by
    spreading one or both ends
  • Fastened by using a rivet set or by peining

22
Types of Rivets
  • Pop Rivet
  • Brass Rivet
  • Copper Rivet
  • Iron Rivet
  • Aluminum Rivet

23
Drilling Holes for Riveting
  • Holes drilled in thicker metal are made with a
    portable drill, or better yet a drill press
  • Uses high speed twist drill bits which are
    hardened for use in metal
