This presentation provides an overview of forge welding, including its principles, classification, process parameters, temperature requirements, tools needed, forgeable metals, common hand tools, advantages, disadvantages, and applications. Forge welding is a solid-state welding process that joins two pieces of metal by heating them above 1000 degrees Celsius and hammering them together. It can be done via hammer welding, roll welding, or die welding and is used in industries like aerospace, shipbuilding, and manufacturing.

4. FORGE WELDING
Forge welding is a solid-state welding
process that joins two pieces of metal by
heating them to a high temperature and
then hammering them together.

5. PRINCIPLES
STEP 1: Metals are heated to the
plastic condition (above 1000 degree
Celsius) in a furnace.
STEP 2: Heated metals are
brought to the anvil from heat source
and superimposed them.

7. CLASSIFICATION
# HAMMER WELDING
Hammering is done by heating the metal to the
proper temperature, coating with flux, overlapping
the weld surfaces, and then striking the joint
repeatedly with hammer.

8. # ROLL WELDING
Here the heated metals are overlapped and passed
through rollers.

9. # DIE WELDING
Here the pieces of metal are heated and then forced
into a die.

10. Process parameters
• Forge-welding temperature
• Amount of deformation
• Forging speed

11. TEMPERATURE
*Typically 50 to 90 percent of the melting
temperature.
*Soft low carbon steel = 1250 to 1300
degree Celsius
*High carbon and alloy steel = 1100 to
1140 degree Celsius
*Wrought iron = little below 1290 degree
Celsius

12. TOOLS NEEDED
# Furnace

13. 
# Anvil

14. # Standard cross peen
hammer
# Flux (Borax / Silica sand)

15. FORGEABLE METALS
# Aluminium alloys
# Magnesium alloys
# Copper alloys
# Carbon and low alloy steels
# Martensitic stainless steel
# Austenitic stainless steel
# Nickel alloys
# Titanium alloys
# Tungsten alloys

16. COMMON HAND TOOLS
# Hammers
# Black-smith’s gauge
# Hot chisel
# Brass

17. ADVANTAGES
# Good quality welds obtained
# Parts of intricate shape welded
# No filler material required
# Required less matching after welding
# Welded joints have low initial cost
# Welded joints easily repaired
# Noiseless process
# High strength welded joints

18. DISADVANTAGES
# Low carbon steel is welded
# High level of the operator skill is required
# Slow welding process
# Weld is contaminated by the coke used in
heating furnace
# Welded joints can not used for collision and
vibration
# Can not be assembled and reassembled

19. APPLICATION
# Aerospace industry
# Production of crank shaft
# Shipbuilding, cycle industries
# Production of pattern-welded blades
# Manufacture of shotgun barrels
# Small tools like railroad equipments,
automobile and trucks, agricultural
machinery
