D3 WELDING IN MARINE CONSTRUCTION

D3 Summary of Committee Responsibilities
The scope of the D3 Committee is to develop general principles relating to welding procedures and their application to marine structures; effect coordination among all bodies in the marine field, concerned with the administration of rules and regulations relating to welding in order to bring such standards into harmony with each other; discuss common welding problems and make recommendations as to their solution; promulgate the use in the marine field of the general Codes and Standards developed by the Society.

Experts Needed for Revision of Two Standards
AWS is seeking shipbuilding professionals to serve as volunteers on two Marine Welding Committees.   The D3A Committee will soon begin reviewing the recently published D3.7 Guide for Aluminum Hull Welding and the D3C Committee has initiated a complete review of D3.5 Guide for Steel Hull Welding.  Topics for review include design, cutting and welding processes/equipment, qualification, construction practices, and inspection.  AWS is looking for experts representing designers, builders, owners and regulatory bodies.
Both Committees intend to confer through virtual meetings, teleconferences and e-mail.  Physical meetings are held in conjunction with the NSRP ASE Welding Technology Panel meetings twice per year.
If you would like to help write either of these two American National Standards, please fill out and submit our on-line membership application.  To learn more about this work, contact Committee Secretary Brian McGrath, (800) 443-9353, X311,
Brian McGrath.
