IMS maintains full time welders, pipefitters, and fabricators on staff. Welder qualifications are maintained in accordance with NAVSEA S9074-AQ-GIB-010/248, Requirements for Welding and Brazing Procedure and Performance Qualification meet ABS and NAVSEA standards. IMS has several welding procedures that have been approved and serialized by Southwest Regional Maintenance Center and the American Bureau of Ships. Company and individual weld procedures are approved after satisfactory test welds are completed by IMS welders and pass destructive testing by a third party. When necessary IMS can and will certify to meet any customer requirements (such as AIT) to perform work.
