The document presents a seminar on welding robots, focusing on their design, operation, and advantages in improving welding processes. It outlines the challenges faced by human welders, such as hazardous working conditions, and argues for the adoption of robotic systems to enhance safety, precision, and productivity in welding tasks. The importance of programming and robot specifications for effective operation is also emphasized.

4.  Robot is a machine carrying out complex series of operations.
 A Machine designed to execute one or more tasks
automatically with speed and precision.
 Welding is a Process of joining different materials.
 The large bulk of materials that are welded are metals and
their alloys.
 Although welding is also applied to the joining of other
materials.
 .

6.  A technique in which metals are welded using the heat generated by an
electric arc.
 The working condition is typically unpleasant and hazardous.
 The arc from the welding process emits ultra-violet radiations which is
injurious to human vision.
 As a result welders are required to wear eye protection in the form of a
welding helmet with a dark window.
 Sparks and smoke are generated during the process are a potential threat to
operators.
 Because of the hazards for human workers in continuous arc welding, it is
logical to consider industrial robots for the purpose.

11.  Robots must be relatively large. It must have
sufficient payload capacity to readily manipulate the
welding gun for the application.
 The work volume must be adequate for the size of the
product.
 The robot must be able to position and orient the
welding gun in places on the product that might be
difficult to access. This might result in need for an
increased number of freedoms.
 The controller memory must have enough capacity to
accomplish the many positioning steps required for
the spot-welding cycle.

14.  Is a series of mechanical linkages and joints capable of
producing all sorts of designed movements.
 The body, arm and wrist assembly of a robot is sometimes
called as a manipulator.

PROGRAMMING.
Robot software is the set of coded commands or instructions
that tell a mechanical device and electronic system, known
together as a robot, what tasks to perform.

 PRECISE MANUFACTURING.
 IMPROVED SAFTEY.
 QUALITY-OF-WORK LIFE
 LESSER TIME.
 HIGHER PRODUCTIVITY.
 MICRO MACHINING OPERATIONS

19.  Properly applied, robots can accomplish routine, undesirable work
better than humans at a lower cost.
 As the technology advances, and more people learn how to use
robots, the robotics market will grow at a rate that will approach the
growth of the computer market over the past thirty years.
 There is every reason to believe that the automation of work through
robotics will lead to substantial increases in productivity, and that
these productivity increases year by year will permit humans to
engage in activities that are cultural and recreational.
 Not only will robotics improve our standard of living, it will also
improve our standard of life.
