Objective:
To design, develop and test a prototype semi-automatic CD or drawn arc (DA) stud gun that is capable of housing and loading multiple studs without requiring operator intervention, utilizing a battery operated power source. NNS currently utilizes the CD process to install the target studs of this project. However, the team does not want to limit the solution to a particular stud welding process. The stud welding process will be determined throughout the project and explained the final report.
Summary:
The stud welding industry has auto fed stud guns/loading systems that are well suited for assembly line work, where the work comes to the welding station in the best ergonomic positions (Flat 1S, Horizontal 2S). However, the stud welding industry does not have an easily portable, lightweight, semiautomatic loading stud system.
NNS will work with Nelson Stud Welding to develop a compact, semi-automatic stud loading gun system with a battery operated power source for all position welding. The system has the potential to increase production throughput and potential working area by reducing need for power at work site while reducing injuries related to repetitive motion and poor ergonomics.
Key Deliverables / Benefits:
This project will be presented at NSRP Panel Meetings and will present the results from the project within a Final Report. This project will develop a semi-automatic Capacitor Discharge Stud Welding gun system that could be implemented throughout the shipbuilding industry and supply base.
