The Application of Grooveless Remelt Deposit Welding to the Joining of Large-Caliber Thin-Walled Projectile to Guide Band

This paper introduces the research on guide band welding in China and other countries, analyzes the characteristics of guide bands produced by remelt deposit welding and the application of the welding process to the joining between thin-walled submunition-based projectiles with a large caliber and launched by a howitzer. In addition, this paper raises the performance testing requirements for the grooveless remelt deposit welding process.
