The study in progress about Hollow Cathode Arc Welding technology in vacuum and its equipment is introduced in this paper. It is an advanced welding technology to solve welding spatters of titanium alloy pressure vessels. Such a welding method is held in vacuum condition and with a little argon gas through a hollow cathode to start a arc. This welding equipment consists of hollow cathode welding torch, vacuum system, welding power source, gas flow control unit and compact control device. The results of arc starting and welding tests for titanium alloy are also presented in detail in the paper. Tensile strength of welding joints has reached the demands of welding standard, esp. no spatters on back weld are obtained in contrast with EBW.
