Observation of Joining Phenomena in First Phase of Friction Welding. Study of Joining Mechanism of Friction Welding. (Report 1).

Joining phenomena and joint strength of friction welded joint between aluminium–magnesium alloy (AA5052) and low carbon steel

“…The friction torque and temperature were recorded with a personal computer through an A/D converter with a sampling time of 0?05 s. The details of these methods have been also previously described. [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] The effect of friction time on the joint tensile strength was also investigated. All joint tensile test specimens were machined to 12 mm in diameter and 84 mm in parallel length.…”

“…The authors also presented the tensile strength of friction welded joints between pure Al and low carbon steel (LCS). 27 If combinations of dissimilar materials such as Al alloy and steel can be joined using the same method as that shown in previous reports, [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] the joining mechanism will be clarified. In particular, clarifications of the joining mechanism are required concerning the weldability of Al alloys with other metals because an expansion in the use of Al alloys is expected.…”

“…In previous works, [15][16][17][18][19][20][21][22][23][24][25][26] the authors clarified the joining mechanism during the friction welding process for similar material joints. The authors also presented the tensile strength of friction welded joints between pure Al and low carbon steel (LCS).…”

Effect of friction welding condition on joining phenomena and joint strength of friction welded joint between brass and low carbon steel

“…To observe the joining phenomena, the authors carried out three experimental methods as follows. The details of these methods have been described in previous reports: [12][13][14][15][16][17][18][19][20][21][22][23] (i) the joining behaviour was recorded by a digital video camera. The friction torque was measured with a load cell.…”

“…In previous works, [12][13][14][15][16][17][18][19][20][21][22][23] the authors clarified the joining mechanism during the friction welding process for similar material joints. Then, the authors presented the joining phenomena between dissimilar materials such as aluminium and titanium in the friction process, and the tensile strength of the joint.…”
