He can provide the following supports: Total Quality Management Systems; quality system auditing; quality improvement and process control studies; statistical process control training and implementation; quality system requirements to MIL-I-45208, MIL-Q-9858, ASME Boiler and Pressure Vessel Code, API-QI Offshore Cranes, and the ISO 9000 Series; structural and mechanical design reviews, gage calibration system, material identification and traceability control, and supplier quality system and auditing.
Expert has experience in welded fabrication; conventional machining processes; press, die and impact forging; metal sawing, cutting, and shearing; metal rolling, forming, bending, stamping, and extruding; metal tube drawing; seamless tube production; abrasive blasting with sand, grit, glass beads, and vapor; and shot peening. He is knowledgeable of conventional available manufacturing facilities and practices.
Expert can provide support in testing for tensile and yield strength, hardness (Rockwell, Brinell, Vickers, Knoop, microhardness, and scleroscope), impact resistance (Charpy V-notch) and toughness, fatigue, creep, formability, low temperature properties, and wear resistance. He can provide microstructural examination of the material in question.
Expert has experience with steel and stainless steel corrosion, iron and steel rusting, atmospheric corrosion, galvanic corrosion, stress corrosion, and with an assortment of protective coatings.
Has evaluated numerous material failures to establish mode and cause of failure (e.g. welds, gears, shafts, and fractures).He has provided selection of materials for various industry applications and products.Has performed development and training of clients in implementation of quality systems to meet customer or industry requirements He has established appropriate compositions and properties of castings for service in various products, including acceptability for weldments.He has participated in several product liability and personal injury litigation cases, providing supporting engineering information and court testimony.
