Objective:

The goal of this project is to experimentally determine handheld laser welding procedures capable of meeting the requirements of NAVSEA TP-248/278. The procedures will focus on 5052 aluminum groove and 5052 aluminum fillet welds, each made in three different thicknesses of sheet metal using 5356 aluminum filler metal. This will involve experimentation using different processes and parameters, verification by destructive and non-destructive testing, and publication of a report with findings and conclusions.

Summary:

Schweitzer Engineering Laboratories Inc. (SEL) is exploring the use of handheld laser welding to increase efficiency and minimize distortion in 5052 aluminum sheet metal welds made with 5356 aluminum filler metal. SEL will investigate the safety hazards and mitigation strategies that will be necessary to implement for welding in a production environment. SEL will also examine porosity and cracking control measures to ensure quality welds.

Key Deliverables / Benefits:

Project results will be distributed through the shipyards, offered for publication in the General Dynamics Electric Boat Welding Engineering Newsletter and at their monthly conference, and a final report will be eligible for unlimited distribution for general awareness of the project and its outcomes.
