Among the most critical parts of any heavy fabrication job, particularly pressure vessels, are the welds.  That’s why our fitters, welders, and quality control personnel have a determination that borders on obsession when it comes to welding quality and accuracy. That clearly shows in the metrics our QC department compiles to measure internal performance. In an average shop 2-3% of welds fail initial inspection and have to be corrected, adding to the job’s cost and production time. Here at Mueller our numbers are consistently a fraction of that. Statistics from the first quarter of 2017 provide a clear example. Of the 3,364 significant welds completed during that period, only 17 were returned for correction, yielding a rejection rate of only ½ % (or more positively stated, an initial success rate of 99.5%). The top achiever, Jomis Joy, performed 791 welds without a single rejection (100%). His colleague, Tomas Castillo completed 746 with only a single rejection (99.9%).

These remarkable ratios don’t happen without a team effort says Vice President of Manufacturing Tommy Tamayo, “It starts with good design and drawings, followed by precise execution by the fitters and welders. We’re extremely proud of our crews and their superb record. This is another reason why our customers trust Mueller quality.”
