COMPANY PROFILE
•
BHEL
•
A CORPORATE GIANTBharat Heavy Electricals Limited (BHEL),
established in 1953, is one of leading power generation
equipment manufacturers in the world.
•
BHEL has 14 manufacturing units, 13 Regional

BHEL, TIRUCHIRAPALLI

The plant achieved its full annual capacity to
design manufacture and supply high pressure boiler equipment
upto 4000 MW in 1984 with boiler unit ratings upto 500 MW.
ABSTRACTS
• The project is about redesigning the
welding machine hanger from stationary to
rotary cantilever type.
• The main advantage behind this are
reduces the movement of the existing one
during loading and unloading operations.
• Overall production time is saved.
STATEMENT ABOUT THE
PROBLEM
• In order to over come the difficulties in circular
job of arc welding process.
• In arc welding slags and non uniform welding
paths are occurs.
• Blow holes that are caused because of vertical
welding process.
• Difficulties to weld in small corners.
REASON FOR CHOOSING THIS
TOPIC
• Welding is mostly applied in boiler accessories
and boiler related plants.
• Reduce the production time.
OBJECTIVE AND SCOPE OF THE
PROJECT
•
•
•
•
Improve the quality of the process.
Reduce the blow holes.
It increases the productivity
It reduce the worker’s load
METHODOLOGY
• Design of welding machine hanger to rotate
about 360 degree.
• Ball bearing attachment for cantilever rotary
movement.
• Selection of inert gas.
• Working process.
