Expert has extensive experience with many arc welding processes, including gas-tungsten arc welding (GTAW), gas-metal arc welding (GMAW), shielded-metal arc welding (SMAW), and submerged-arc welding (SAW). He is familiar with both manual and automatic versions of these processes, as applied to carbon steels, stainless steels, aluminum, nickel alloys, and titanium alloys. He has welded these materials in compliance with both government specifications as well as aerospace and boiler code requirements.

He has been a member of Subgroup General Requirements of Section IX of the ASME Boiler and Pressure Vessel Code since 2005. He has headed numerous taskgroups. He is available to present code cases to the ASME BPVC.

As a member of the ASME BPE MJ subcommittee, he has helped develop requirements for tube-attachment welds performed by automatic welding. He also wrote a set of essential variables for the qualification of welding operators, specifically for the performance of automatic orbital GTAW.

As a member of the ASME BPE committees, he has written rules that affect the design of piping systems, the inspection of the welds on the piping systems, and the qualification of both the welders and inspectors who fabricate and inspect these piping systems.

In the AWS Certified Welding Inspector Seminars that he teaches, he covers the processes, characteristics, variables, and discontinuities found in solid-state welding processes. He has developed spot welding processes for a fabricator who makes containers for military applications. He has also developed resistance welding processes for use in attaching tubes to high-pressure containers for nuclear weapons components.

Work History

Years Employer Title Department Responsibilities
Years: 2006 to Present Employer: Undisclosed Title: Owner/Operator Department: Responsibilities: He is the owner/operator of an engineering consulting firm, providing welding and metallurgical engineering services to companies fabricating metallic goods in the pharmaceutical, aerospace, defense, refinery, and structural industries. He provides training, failure analysis, code compliance, and specification review services.
Years: 2002 to 2006 Employer: Purity Systems, Inc. Title: Quality Manager Department: Engineering/Training Responsibilities: He was in charge of Quality Control for a small third-party inspection firm who provided inspectors for pharmaceutical firms to inspect the fabrication of the equipment and tubing systems during the construction of their drug-manufacturing facilities. He wrote the inspection company's Standard Operating Procedures for inspection as well as their semi-monthly Technical Highlights, which were technical notes that served as continuous training briefs. He was in charge of the company's internal auditing program.
Years: 1998 to 1999 Employer: Dynamic Materials, Inc. Title: Manufacturing Engineer Department: Explosive Fabricators Responsibilities: He was in charge of the company's seam welding activities, in which alloys or pure materials were welded together in preparation for being explosively bonded to thick carbon-steel backing plates. The materials welded were stainless steel, inconels, pure nickel, pure titanium, pure zirconium, silicon bronze, and aluminum.
Years: 1997 to 1998 Employer: Lockheed Martin Title: Testing Engineer Department: Astronautics Responsibilities: He developed and supervised testing of various aerospace materials, including fabrics, cardboard, plastics, pure metals, alloys, and foam in accordance with ASTM standard practices and internal specifications.
Years: 1995 to 1997 Employer: Lockheed Martin Title: Welding Engineer Department: Astronautics Responsibilities: He supervised and supported the production welding of stainless steel and inconel alloys in the fabrication of the hydrazine fuel systems used to propel the centaurs of the Titan and Atlas rocket programs.
Years: 1992 to 1995 Employer: E G & G Title: Senior Development Engineer Department: Rocky Flats Plant, Golden, Colorado Responsibilities: He was liaison between Rocky Flats Plant and Lawrence Livermore Laboratories for the development of weld on stainless steel components used in the governments nuclear weapons program.
Years: 1982 to 1992 Employer: Rockwell International Title: Development Engineer Department: Rocky Flats Plant, Golden, Colorado Responsibilities: He planned, developed, and documented welds for aluminum, copper, and stainless steel components for Sandia National Laboratories and Lawrence Livermore Laboratories designed nuclear weapons components.
