The tests were performed on welded joints that were not heattreated and welded joints that were annealed (at 735-745°C for 0.5 hours) after welding. The results of the tests were used as a base to elaborate a Welding Procedure Specification.

The outer part of the composite pipe is made of Sandvik 3R12 steel (grade ASME 304L/SA) and has austenitic microstructure, whereas the inner pipe – of Sandvik 4L7 steel (grade ASME SA-210A1) and has ferritic pearlitic microstructure. The results of the tests were used as a base to elaborate the Welding Procedure Specification allowing to obtain high quality joints with correct structure and high mechanical properties.
