| Abstract Scope |
For years, the defense industry has been driven to make their armored combat vehicles lighter without compromising its security. Friction Stir Welding (FSW) has been identified as an avenue to promote this objective. Under the proper circumstances, the FSW process can produce sound welds that do not require extra armor to protect a degraded and vulnerable heat-affected zone (HAZ), as observed in traditional arc welding. This work presents the exploration of advanced process control and pre/post-heating during FSW of armor steels to optimize microstructure and joint performance, with emphasis on toughness improvement. |
