Dual beam laser keyhole welding of steel/aluminum lapped joints
Laser welding of Q235 low carbon steel and 6061 aluminum (Al) alloy was carried out by using a dual beam fiber laser in keyhole welding mode in a steel-on-Al lapped configuration. The influence of processing parameters of power distribution ratios (Rs ) and dual beam laser distances (d 1) on the wel...

| 520 | |a Laser welding of Q235 low carbon steel and 6061 aluminum (Al) alloy was carried out by using a dual beam fiber laser in keyhole welding mode in a steel-on-Al lapped configuration. The influence of processing parameters of power distribution ratios (Rs ) and dual beam laser distances (d 1) on the weld shapes, microstructures of intermetallic compound (IMC) layers, microhardness and tensile resistance of the steel/Al joints was studied. Soundly welded steel/Al joints have been achieved by using dual beam laser keyhole welding at Rs = 0.67 and d 1 = 1.5 mm. The key factor affecting welding defects is the control of the penetration depth of the welds, and good weld shape has been achieved when the penetration depth of the welds is below 700 m. The formation of IMC phases consisted of Fe4Al13, Fe2Al5 and FeAl2 phases is only limited to the weld/Al interface when the steel/Al joint has a relatively low penetration depth of the welds in the steel/Al joint. The maximum tensile resistance of the steel/Al alloy joints of 115.6 N/mm is obtained under the conditions of Rs = 0.67 and d 1 = 1.5 mm. The fracture surface reveals a mixed failure occurred in the Al alloy leading to high tensile resistance of the steel/Al joints. | ||

Dual beam laser keyhole welding of steel/aluminum lapped joints |
| abstract |
Laser welding of Q235 low carbon steel and 6061 aluminum (Al) alloy was carried out by using a dual beam fiber laser in keyhole welding mode in a steel-on-Al lapped configuration. The influence of processing parameters of power distribution ratios (Rs ) and dual beam laser distances (d 1) on the weld shapes, microstructures of intermetallic compound (IMC) layers, microhardness and tensile resistance of the steel/Al joints was studied. Soundly welded steel/Al joints have been achieved by using dual beam laser keyhole welding at Rs = 0.67 and d 1 = 1.5 mm. The key factor affecting welding defects is the control of the penetration depth of the welds, and good weld shape has been achieved when the penetration depth of the welds is below 700 m. The formation of IMC phases consisted of Fe4Al13, Fe2Al5 and FeAl2 phases is only limited to the weld/Al interface when the steel/Al joint has a relatively low penetration depth of the welds in the steel/Al joint. The maximum tensile resistance of the steel/Al alloy joints of 115.6 N/mm is obtained under the conditions of Rs = 0.67 and d 1 = 1.5 mm. The fracture surface reveals a mixed failure occurred in the Al alloy leading to high tensile resistance of the steel/Al joints. |

The formation of IMC phases consisted of Fe4Al13, Fe2Al5 and FeAl2 phases is only limited to the weld/Al interface when the steel/Al joint has a relatively low penetration depth of the welds in the steel/Al joint. The maximum tensile resistance of the steel/Al alloy joints of 115.6 N/mm is obtained under the conditions of Rs = 0.67 and d 1 = 1.5 mm. The fracture surface reveals a mixed failure occurred in the Al alloy leading to high tensile resistance of the steel/Al joints.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">IMC layers</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Dual beam laser keyhole welding</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Microhardness</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Tensile resistance</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Steel/Al joint</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Boxu</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Li</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">He, Dingyong</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier</subfield><subfield code="a">Munnur, Ravi Kiran ELSEVIER</subfield><subfield code="t">DIAGNOSTIC ACCURACY OF ASLA SCORE (A NOVEL CT ANGIOGRAPHIC INDEX) AND AGGREGATE PLAQUE VOLUME IN THE ASSESSMENT OF FUNCTIONAL SIGNIFICANCE OF CORONARY STENOSIS</subfield><subfield code="d">2016</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV014190494</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:256</subfield><subfield code="g">year:2018</subfield><subfield code="g">pages:87-97</subfield><subfield code="g">extent:11</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.jmatprotec.2018.02.016</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_21</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_40</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2009</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2010</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">51.00</subfield><subfield code="j">Werkstoffkunde: Allgemeines</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">51.32</subfield><subfield code="j">Werkstoffmechanik</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">256</subfield><subfield code="j">2018</subfield><subfield code="h">87-97</subfield><subfield code="g">11</subfield></datafield><datafield tag="953" ind1=" " ind2=" "><subfield code="2">045F</subfield><subfield code="a">670</subfield></datafield></record></collection>
