Operating and Quality Control Procedures....

At the start of a job, procedures and specifications are discussed between Quality Control, Shop Foreman and Job Leadman to insure a mutual knowledge of the end product. Each man that is involved in the different stages of production is then informed of tolerances, welding specifications, and assemble procedures that must be followed. Materials to be used on jobs are checked with Heat Number and Mill Certified Test Reports to insure material conforms to job specifications. Test Reports are copied and provided upon request along with documentation of welding procedures to all customers and inspection firms. Following completion of first item, all dimensions are checked including weld size and length. After production begins, Quality Control visually inspects parts before shipment. Each welder is certified in the process and material being used, and is assigned a letter stamp and stamps each part when complete. Head of Quality Control is Steven M. Sears who is a Certified Welding Inspector, #89060861. Our shop is a Los Angeles City Certified fabricator.
