This is a case study of total quality control approach for reduction of percentage repair during fabrication and erection of new water conductor system. The Sub-merged Arc Welding without SMAW backing was used for welding of A517 Gr. F & Sumiten 780s (Quenched & Tempered steel). This process was used for the fabrication of penstock / steel liner for tunnel in M/s. PES Engineers workshop at Madap. The procedure was qualified by PES in workshop. While implementing the procedure on job, the percentage repair was 8 to 16% during December 2002 to April 2003. The paper describes how percentage repair was reduced using total quality control approach.

This is a case study of total quality control approach for reduction of percentage repair during fabrication and erection of new water conductor system. The Sub-merged Arc Welding without SMAW backing was used for welding of A517 Gr. F & Sumiten 780s (Quenched & Tempered steel). This process was used for the fabrication of penstock / steel liner for tunnel in M/s. PES Engineers workshop at Madap. The procedure was qualified by PES in workshop. While implementing the procedure on job, the percentage repair was 8 to 16% during December 2002 to April 2003. The paper describes how percentage repair was reduced using total quality control approach.
