Mechanical and corrosion properties of arc, electron beam and laser welded joints in alloy Ti-6Al-4V are compared, allowing for peculiarities of thermal cycles of laser welding. Susceptibility of the laser weld metal to stress corrosion cracking in an aggressive environment is found to be by an order of magnitude higher than that of the arc weld metal. Annealing of welded joints does not decrease their sensitivity to cracking.
Keywords: arc welding, electron beam welding, laser welding, titanium alloys, mechanical properties, stress corrosion resistance
