3.  Welding :- Welding is a permanent joint between two or more similar or dissimilar materials by
heating them to a certain temperature with or without the application of pressure or by the pressure
alone and with or without adding filler materials.
 Automation :- Automation or automatic control, is the use of various control systems for
operating equipment such as machinery.
 Computer Integrated Manufacturing (CIM) :- CIM has been introduced in various
production environments with different purposes including human productivity improvement,
product quality improvement, capital resource productivity improvement and providing rapid
response to the market demands.

4.  Robotic Welding :-
• Robotic welding is mainly concerned with the use of mechanized programmable tools, known as
robots, which completely automate a welding process by both performing the weld and
handling the part.
• At its simplest a robot is a manipulator that can be programmed. The manipulator is driven by
actuators like electric motors and is controlled by a computer.
• Welding Robot has 5-6 linear and rotational axes to do different task.

5.  Different Techniques for doing Welding-
• Manual Welding- all operations done by hand
• Semi automatic Welding- Welding variables are controlled automatically, Wire feed speed in GMAW •
Duration of current in resistance welding with a gun welder.
• Automatic Welding - Some welding variables are done manually
• Remote Welding - Remote welding is similar to automated welding. Uses In nuclear power plant.
• Robotic Welding - Basically a part of Automated welding, but all technology is available here

6. • Arc Welding
• TIG Welding
• MIG welding
• Spot Welding
• Stick welding
• Friction Welding
• Laser Welding
• Plasma Welding

7.  ARC WELDING
 Arc welding is a continuous process.
 Continuous arc welding is used to make long welding joints in which an air tight seal is
often required between the two pieces of metals being joined.
 Currents are typically 100 to 300A at voltages of 10 to 30V.

8.  The process uses an electrode in the form of a rod or a wire of metal to supply the high
electric current needed for establishing the arc.
 The arc between the welding rod and the metal parts to be joined produces
temperatures that are sufficiently high to form a pool of molten metal to fuse the two
pieces together.

temperatures that are sufficiently high to form a pool of molten metal to fuse the two

9. Robotic Arc Welding :- For robot applications two types of arc
welding processes seems to be most practical, namely: gas metal arc welding
(GMAW) and gas tungsten arc welding (GTAW). Gas tungsten arc welding is
also called MIG welding for metal inert gas welding.

12.  Spot Welding
 Spot Welding :-
• Spot Welding classify under the resistance welding.
• spot welding acts by generating heats with use of a high current, approximately
about 1000A – 100,000 A.
• The welding guns are the main part of the welding. It comes in 2 parts, these guns do
similar function as to make a close loop circuit, connecting the power supply to the
weld spot.
• The weld spot is so called the Heat Affected Zone (HAZ).
• spot welding which might be called a discontinuous process.

13.  Robotic Spot Welding

14.  Weld Timer :- An automated spot welding cell needs to control equipment to initiate and the
time duration of current.
 SPOT WELDING GUNS :- The main component of spot welding

15.  Unlike fusion welding processes, for example arc welding, electron
beam welding, and laser welding, the FSW process takes place in the
solid phase below the melting point of the materials being joined.
 Ability to weld alloys that are difficult to weld by fusion welding
processes.
 Uses a non-consumable tool, requires no filler wire, or gas shielding.

17.  During laser welding, the laser, heats the material to melting
temperature.
 The beam is focused by means of optics.
 The weld seam is created by the relative motion between the laser
beam and the workpiece.
 To protect the weld surface against oxidation, argon is used as a
shielding gas during the process

19.  To Improve productivity.
 Shortage of skilled labors.
 To reduce labor fatigue.
 Health issues.
 Safety requirement.
 To handle job in hazardous environment.
 Cost reduction.
 Increased productivity.
 Consistent accuracy.
 Minimum wastage of time & materials.
 Stabilized labor charge; No work, No pay.
 Solution of skilled labors.

20.  ABB (ASEA Brown Boveri)
 Staubli
 B+M Surface Systems GmbH
 Kuka
 Omron Adept Technologies
 FANUC Robotics
 Kawasaki

22.  Numbers of components produced by A robot are 2.5 to 3.5 times greater than that produced
manually over the same Span of the time.
 There is every reason to believe that the automation of work through robotics will lead to substantial
increases in productivity.
