Acquisition of a Laser System for the Development of Hybrid Friction Stir Processing
Abstract
This document includes the details of the acquisition of a fiber optic laser system (YLS-1500-S2T from IPG Photonics Corporation) and its integration with existing friction stir processing (FSP) machine for developing laser hybridized friction stir processes to expand the existing capabilities of FSP machine. Historically, the thermal cycle and material flow have been integrally coupled in the friction stir process. The primary requirement of heat input leads to process parameters that are not best suited for the microstructural control. Addition of a laser beam as an independent heat source can expand the flexibility of microstructural control during FSP. The primary function of this DURIP award was to acquire a laser system for development of hybrid FSP technique. A 1.5 kW fiber laser system was acquired using the DURIP funds. The successful integration of the laser with friction stir processing and its potential for future application has been demonstrated through two case studies (a) force control and (b) tool traverse speed control. Currently, a collaborative work is in progress with ARL to utilize this hybrid processing capabilities to achieve unique microstructure, which is the long term goal of this DURIP award.
