Automatic Weld Inspection

For the year 2000, welding expenditures in the U.S manufacturing, mining and construction industry was about $34 million. In order to test these welds in a non-destructive manner, nearly half a million radiographs are being produced every year. General Manager-Operations wanted a team at the imaging lab to develop new methodologies to identify defects in welds for analyzing the radiographs.

Induction Welding Case Study

19For the year 2000, welding expenditures in the U.S manufacturing, mining, and construction industry were about $34 million.In order to test these welds in a non-destructive manner, nearly half a million radiographs are produced every year. Mr.R.J.Pardikar, Senior Deputy General Manager for the Quality/NDT division at the company, wanted a team at the Centre for Nondestructive Evaluation (CNDE) lab, Indian Institute of Technology (IIT), Madras to conduct a feasibility study of the possible Nondestructive testing methods applicable to the problem or develop new methodologies to identify defects in induction pressure welds.

Lorn Manufacturing Case Study

lornmanuThe Lorn Manufacturing case study details the dilemma Jim Russell faced after losing three fingers in a horrible accident that occurred while he was cleaning a lap winder in an industrial plant. Who is responsible? Did Russell fail to follow procedure while performing his maintenance duties, or is it the manufacturer’s fault for not following proper safety guidelines when designing the machinery? Find out the jury’s verdict and learn about engineering ethics.

Students use this case study to develop an understanding of the following key objectives:

  • Implementation of safety procedures in a manufacturing plant
  • Application of codes and standards in professional environments
  • Qualifications engineers must have to serve as expert witnesses
  • Proper communication skills in a professional environment, such as a manufacturing plant

Mauritius Auditorium Design Case Study

5This multimedia courseware focuses on an acoustical design of the polyvalent hall at the Swami Vivekananda International Convention Center on the island of Mauritius. The multi-use hall was praised as a “fabulous building and quite and achievement” after successfully hosting a United Nations conference without any acoustical problems. Later, as a band rehearsed for the building’s first rock concert, the sound quality fell severely short of expectations. A problem arose with the loud music, requiring a reconsideration of the hall’s design before it could provide satisfactory acoustics for any similar events.

The materials provided here will introduce students to the following concepts:
