Electron Beam Welding (EBW) 0.1.1.2.1.T6.95.12
shielding gas nozzle (optional) Laser beam Plasma plume Molten material workpiece motion High Energy Density Processes Laser Beam Welding (LBW) • Single pass weld penetration up to 3/4” in steel • Materials need not be conductive • No filler metal required • Low heat input produces low distortion • Does not require a vacuum Plasma keyhole Keyhole welding
Factors that Influence Process Selection • Material joining needs • Capabilities of available processes • Cost • Environment • Required welding speed • Skill level • Part Fit-up 0.1.1.2.7.T31.95.12
