Abstract
Investigations on application of equipment and technology for orbital TIG welding to repair pipelines inside functioning space objects were carried out. Properties and structural peculiarities of 12Kh18N12T steel tubular joints made by auto-pressing under conditions of decreased effect of the Earth gravitation were studied.
 
 
Keywords: orbital TIG welding, pipelines, stainless steel, position welds, decreased gravitation, microchamber, tubular joints, mechanical properties, macro- and microstrucutre, microhardness
