This document discusses industrial engineers and their focus on productivity improvement. It states that industrial engineers are concerned with designing, improving, and installing integrated systems to make more efficient use of resources like people, machines, materials, and capital. The goal is to produce more output without increasing the level of inputs. It also briefly mentions some common joining methods like mechanical fastening, adhesive bonding, and welding used in fabrication processes to join multiple elements into a single part for things like aircraft, bridges, and machinery.

1. Industrial & production Engineer in short termed as
Industrial Engineer (IE).
IE is concerned with the design, improvement and
installation of integrated systems of people, materials,
equipment and energy

2. Industrial Engineer
If industrial engineer had to focus on only one concept to describe his field
of interest and objective, it would have to be productivity improvement.
Productivity improvement implies:
 A more efficient use of resources
 Less waste per unit of input supplied
 Higher levels of output for fixed levels of input supplied
The inputs may be:
 Man
 machine
 Materials
 capital

3. Industrial Engineer
The mission would be to try to produce more or to serve
better without increasing the resources being consumed

5. Joining methods
Joining two or more element to make a single part is
termed a fabrication process.
Example: aircraft, ship bodies, bridges, welded
machine frames, sheet metal parts, etc
The various fabrication processes can be classified as
follows:
 Mechanical joining by means of bolts, screws and rivets
 Adhesive bonding by employing synthetic glues
 Welding, Brazing and soldering

6. Welding
 Welding is the permanent joining of two materials.
 Here the interface of two parts to be joined are brought
to a temperature above the melting point and then
allowed to solidify. Then the permanent joining take
places.
 Because of the permanent nature of the joint and its
strength being equal to or sometimes greater than that
of the parent metal.
