Alpha Magnetics employs advanced tungsten inert gas welding techniques (TIG) with high purity argon as the inert gas medium. Manual as well as automated orbital welding machines are at the heart of all welding operations. Alpha Magnetics adheres to stringent UHV welding standards and practices including that of nonfiller material, and all internal fusion weld joints. External weld joints are not used unless required for structural reinforcement and then, limited to skip or span weld configurations. In the event that a weld joint cannot be made internally, a one hundred percent full penetration external weld will be used.
