| dc.description.abstract | DMS Industrial Constructors is a fast-growing industrial contractor and one of the largest in Western Canada. DMS currently operates a fabshop for prefabrication of structural steel and piping components for its major projects. The current fabshop is reliant on solely manpower and utilizes underdeveloped welding equipment which results in slow manufacturing speed and welding inconsistencies. Aligned with DMS’s interest in continuous improvement, Team 10 has been tasked with improving the current welding process and streamlining the overall workflow by incorporating automated or semi-automated technology to a certain degree. The team is to focus on implementing design changes and analysis to improve the first stage welding aspect of DMS’s current workflow which involves circumference welding and welding of smaller pipe components. DMS has also outlined improving the current defect rate of 2%, and welding speeds of 20”- 25” and 40”- 60” per day for stainless steel and carbon steel pipes respectively. DMS has also specified that the recommended solution by the team should be capable of welding pipes ranging from 2” to 12” in diameter, Schedule 10 to Schedule 80 in thickness and up to 40ft in length. Also, the final design should comply with Canadian Standards Association (CSA) while staying within the $1,000,000 budget. The deliverables specified by DMS include a detailed cost summary, bill of materials, failure mode and effect analysis, supplier contact list, payback analysis, and construction drawings of the new system. To achieve a feasible solution, the welding process was broken down into 3 major systems based on functionality- Welding Robot, Turntable and Roller Stand. Various design concepts were researched, and a final concept that satisfies the needs and target requirement was selected. The selected welding system was the Spool Welding Robot (SWR) manufactured by Novarc Technologies which is adaptable to the existing turntables and has an interface to generate reports that keeps track of quality. The SWR also advertises a defect rate of less than 1% and a welding speed of 200”-350” and 569”– 998” per shift for carbon steel and stainless steel respectively. The current turntable is not efficient for pipes with diameters less than 4”. Therefore, the LJ welding 12P-900 portable turntable was selected to efficiently work with pipes with smaller diameters. Lastly, the HD2-300 roller stands also made by LJ welding was selected primarily because of its compatibility with the SWR and turntables. The final system will cost a sum of $607,184.00 which is within the $1,000,000 budget and will result in a 50% reduction in the current defect rate, more than 300% increase in the current welding speed for both stainless steel and carbon steel pipes. These improvements implies that the current workload can be completed in 76 days rather than 260 days for the existing system (240% improvement). A payback analysis on the system deduced that the payback period is 348 operational days with current workload. | en_US |
