Techniques
used for Laser Welding
1- Contour Welding
In
contour welding, a laser is guided along a predetermined welding pattern. The
material only melts on the path that the laser is directed. Relative motion is
achieved by moving the laser source, the part or a combination of both.
2-Simultaneous
Welding
In this technique, a laser will heat the entire weld area
simultaneously. Almost any beam geometry can be generated by means of a
special, state-of-the-art beam shaping elements. Parts, up to an area that
equals 2.000" diameter,...

Laser Plastic Welding
Laser welding process is epically used for the plastics. Lasers are
becoming increasingly popular for joining two components together because the
technique is fast, reliable and inexpensive. Transparent and Absorbent
Thermoplastics Laser welding relies on two types of polymers, transparent or
absorbent. Most thermoplastics in their natural state are transparent at
typical laser wavelengths. Additives, such as...
Function of Drum Gear in a Bike
Motorcycle transmissions are made up of gears in constant
mesh. Because of this, there are no syncros to speed up the gears. The gears
are already spinning. To change between gears you need some kind of gear
shifter mechanism to go along with that gear shift lever.
Gear shifters come in three different types.
1. Drum Shifters

Drum Slider Forks
·
Shaft Slider forks
2.

What is Industrial
Engineering?
Industrial
Engineering is a profession that, deals with all those studies/techniques that
are used for not only improving the existing work methods but also is to
develop the efficient procedures to done a job. The IE/work study approach
employs specialists working as individuals which is contrary to worker- group
orientation of QC circles. The one and
only objective of the IE is to improve effectively the existing...
