The feasibility of using earth bounded welding techniques in the space environment has been investigated. A literature survey on welding in space reveals numerous aspects about the work done in different countries. The survey indicates the need of a more detailed focus, since no welding experiments have been performed in space since July 1984 (Salyut-7). Addressing the peculiarities of different welding processes, such as environmental restrictions, helped in evaluating and analyzing the selected processes. In order to study the use of a welding process, one should also analyze the ways to test the welds produced. Consequently, non-destructive testing (NDT) techniques with potential use in the space environment were evaluated. A comparison of the various NDT techniques showed parameters,…
