Development of Lightweight Fume Extraction Welding Guns

摘要

This report describes a project conducted for the NSRP SP-7 Welding Panel to develop a lightweight fume extraction welding gun for shipyard use. Shipbuilders are interested in fume extraction welding guns to improve worker comfort meet workplace safety requirements as well as environmental regulations. Current fume extraction welding guns have limited flexibility and are bulky compared to conventional guns Shipbuilders desire improved fume extraction guns to make them practical for widespread use. The objective of this project was to develop a lightweight fume extraction gun for GMAW and FCAW welding processes that incorporates ergonomic engineering to improve usability Edison Welding Institute performed the project with participation from Newport News Shipbuilding Ingalls Shipbuilding National Steel and Shipbuilding Company, and welding equipment manufacturers. The project gathered past experience with fume extraction welding guns, evaluated current guns, developed a prototype lightweight gun, and evaluated this gun during shipyard trials.
