“…The microstructure of API 5 L Grade B is composed of ferrite and perlite. The API 5 L X65 typical microstructure is composed of polygonal ferrite (PF) and martensite-austenite (M-A) 10,11 . Three welded samples were produced with a MASF 1500 friction welding machine using different combinations of loading parameters according to Tab.…”

“…Buzzatti et al 11 pointed out that a pipeline route build up with API grade B steel should be cheaper than one that using API 5 L X65 pipes at a cost of mechanical strength. By the other hand, a joint with a superior material, as is the case of API 5 L X65, results in improved welded joint microstructure, which promote enhanced mechanical and metallurgical properties through the addition and optimization of alloying elements 12 .…”

Residual stresses (RS) in pipes welded by a fully automated friction welding process, called FRIEX, are investigated using the contour method (CM) and the X-ray diffraction method (XRD). Samples were produced using a self-developed equipment, which is based on the interaction between a consumable intermediate rotary ring and two stationary pipe sections, by varying the loading rate applied during the welding of API 5L B pipes with an API X65 ring. Mechanical and metallurgical properties were locally analyzed through metallography and microflat tensile tests. RS measured by XRD and CM showed comparable values; tensile zones were found in the pipe HAZ and compressive stresses were found in its adjacent areas. Tensile RS of approximately half the local yield strength of the components were also found, mostly on the internal surface, and their values decrease with increasing welding loads. Microflat tensile tests showed an increase in yield strength of pipe TMAZ and HAZ, with a clear influence of loading rates.

In this study; a practice has been conducted to examine the performance of orbital flux cored arc welding (FCAW) method, which is a new method. Steel pipes of API 5L X70M quality produced for oil and natural gas pipelines were used in the experiments. Experiments were carried out under industrial field conditions in order to reach realistic results. The test samples were joined by orbital gas metal arc welding (GMAW) method using flux cored wire and the joining samples were examined in detail and the metallurgical and mechanical properties of the weld zone were analyzed.
