In order to expand the application of aforementioned gas metal-arc welding; it is made to adapt with development in science and technology at a high speed; people have carried out Exploration & stu dy to it; such as " welding journal " the 34th volume the 8th phase 55th ~ 58 pages of introductions have " under water gas metal-arc welding "; and for example " Beijing University of Technology's journal " the 39th volume the 7th phase 971-975 page publish and have the melt-extracted steel fibre of gas metal-arc welding " under the electromagnetic action ", etc.In addition, technical information about gas metal-arc welding welding can be seen in disclosed Chinese patent literature, typically as " automatic gas metal arc welding overlaying welding device with horizontal rotation " of Authorization Notice No. CN201283462Y recommendation, though due to this patent formula welding mechanism together with welding gun be rotate, but be static by the workpiece of built-up welding, thus the gas metal-arc welding welder category under the Elevated Gravity that applicant says is not belonged to, and make the pivotal power drive mechanism of welding mechanism because this patent formula adopts and make the welding gun elevating mechanism (patent claims horizontal lifting mechanism) of welding gun oscilaltion, thus complicated integral structure." a kind of mould position narrow clearance melting electrode automatic soldering device used for gas shield welding " that and for example application for a patent for invention publication No. CN103273178A provides; this patent application scheme has the principle with aforementioned CN201283462Y, and namely welding gun is adjustable and welded part remains static.
Because the size of acceleration of gravity can produce corresponding impact to gas metal-arc welding welding process; again owing to being showed no all corresponding technology enlightenments in patent and non-patent literature disclosed at present; thus the gas metal-arc welding solder technology (comprising welder) explored under Elevated Gravity has has following prospective positive effect in mind; because the acceleration of gravity of the welding surroundings residing for the current mankind is 9.8m/s
2, and the technology that the mankind explore space is increasingly mature, and process is constantly accelerated, the foreseeable future, and the mankind will inevitably carry out Activities in space, and even stops in remote other celestial body of liftoff ball.Known, the acceleration of gravity of moonscape is only 1/6th of the earth, and areographic acceleration of gravity is only 2/5ths of the earth, etc.So due to the change of acceleration of gravity, welding procedure also must be different from the earth, and namely current other celestial body of simulation that obtains at the earth's surface is less than 9.8m/s
2acceleration of gravity welding surroundings objectively comparatively difficulty, only explore in part elevator and space craft, thus condition is very limited.It can thus be appreciated that simulation is greater than terrestrial gravitation acceleration (9.8m/s
2) hypergravity welding surroundings undoubtedly there is help for instructing following welding under the environment of space and even other celestial body and so on.Technical scheme described below produces under this background.
