AbstractThe space Gas Hollow Tungsten Arc (GHTA) welding has been developed since 1993. In order to establish the space welding technologies necessary for the space development, the space Diode Laser (DL) welding which welding principle is completely different from the space GHTA welding is being developed. The DL welding experiments using stainless steel clarified the features of the DL welding and evaporating phenomena. The metal evaporation becomes a serious problem, because it damages the optical devices, and becomes a cause of space pollution.
