Aluminium Strip

Friction stir welding (FSW) of AA2014 aluminium alloy was performed by sandwiching pure aluminium (Al) in the form of strip between the abutting surfaces. Mechanical and corrosion behavior of weld joint with and without pure aluminium addition was compared. Friction stir welding was carried out at rotational speed of 931 rpm and traverse speed of 41 mm/min. Pure aluminium strip of 1 mm thickness was used for incorporating Al in weld nugget zone. Microstructure analysis was carried out using optical microscope and FESEM with energy dispersive spectroscopy (EDS). Microhardness and tensile testing were performed on the weld joints. Corrosion behavior was investigated using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (Tafel) test. FESEM analysis was performed before and after corrosion test. Traces of pure aluminium strip were observed in the microstructure. The incorporated strip was found not to be uniformly distributed in the nugget zone. Pure aluminium addition reduced the extent of formation of the second phase particle in the nugget zone as compared to the normal FSW joint i.e. without Al addition. This metallurgical homogeneity resulted in better corrosion resistance of the Al added weld joint than the normal FSW joint.

Analysis of possible shipbuilding application of friction stir welding (FSW) method to joining elements made of AlZn5Mg1 alloy In industrial practice the welding of Al- alloys is usually performed under pure argon shielding by means of MIG or TIG methods. In recent years new joining techniques such as friction stir welding (FSW) have appeared. Joints of EN AW-7020 T6 alloy elements welded by using FSW method have been tested. Results of static tensile tests, transverse bending tests as well as tests on stress corrosion susceptibility are presented. Parameters of friction welding (FSW) applied to joints of plates made of AlZn5Mg1[7020] alloy are given. Stress corrosion tests have been performed by using slow-strain-rate testing method (SSRT) in compliance with PN-EN ISO 7539-7 standard. The tests were conducted in air and 3.5% NaCl water solution. The following parameters have been measured during the tests: time to failure - T [h], maximum failure load - F [N], fracture energy (area under stress-elongation curve) - E [MJ/m3], relative elongation of specimen - A10 [%], maximum tensile stress - R [MPa], as well as percentage reduction of area - Z [%]. On the basis of the obtained test results it was concluded that the joints welded by means of FSW method show good resistance to stress corrosion at satsifactory strength properties, which indicates that application of friction welding by using FSW method in shipbuilding industry is purposeful.

Friction stir welding (FSW) joints of AW 5083 and AW 5059 alloys were used for the study. Mechanical properties, resistance to stress corrosion cracking (SCC) were investigated and metallographic tests were performed using an optical and scanning microscope (SEM). The parameters of friction welding are also given. Stress corrosion was investigated by the method of slow strain rate testing (SSRT) in air and 4.5% NaCl aqueous solution. During SCC tests elongation, strength, fracture energy and time to break were measured. Very good strength of the tested alloys was found with good resistance to stress corrosion cracking. The aim of the study was to determine the possibility of using the AW 5059 and AW 5083 friction welded (FSW) alloys in marine structures, using stress corrosion resistance as a criterion
