Seminar on
"Joining of Copper and Copper Alloys – Latest Developments"
Bangalore
25th November, 2011
The
above seminar was organized by Indian Copper Development Centre (ICDC) in
Joining
technology of copper and copper alloys plays an important role in fabricating
various copper based products. In order
to achieve optimum production efficiency and quality, the joining process
namely soldering, brazing and welding, must be carefully controlled. Moreover several new developments have taken
place in joining technology in order to improve the operational efficiency and
performance of the joints.
ICDC
organized this seminar in order to create awareness on latest developments
taken place in the field of soldering, brazing and welding techniques of copper
and copper alloys.
Eight
papers were presented and about 60 participants attended the programme from all parts of the country. They represented not only technology
suppliers for soldering, brazing & welding but also research institute,
electronic industries, solar water heater manufacturers, electrical equipment
manufacturers, air conditioning & refrigeration manufacturers, ship
builders, oil refinery, copper based product manufacturers, etc.
During
the opening session Mr. Kurien Verghese,
Director,
Hybrid Metals Pvt. Ltd., welcomed the participants. He mentioned how this type of focused
technology oriented seminars can help in creating awareness on technology
developments aiming at quality improvement, minimizing rejection and improving
