Corrosionpedia explains Spray Welding
Spray welding includes the use of industrial plasma, flame, detonation guns, arc sprays and high-velocity oxy fuel. Due to the significant heat produced during spray welding, procedures and regulations must be followed carefully and consistently to prevent harm to individuals and the environment.
