Aluminum 6061-T6 alloy of thickness 3mm is friction welded by this experimental examination. The rotational speed of the tool is varied like 560, 900, and, 1400rpm. The feed is selected as 20, 63, and, 100mm/min. The tilt angle is kept at 0 degree. The welded joints are produced by taking different welding angle such as 0-, 30- and 60- degrees. The tool steel pin having a circular and hexagonal profile is used to produce the welded joints. The tensile samples are extricated from the welded specimens and followed for the testing. The maximum tensile strength is observed like 213MPa, 256MPa, and 200MPa at 0-, 30-, and 60-degrees welding angles respectively with the use of a circular profiled probe. The highest tensile strength has arrived like 191MPa, 207MPa, and 212MPa at 0-, 30-, and 60-degrees welding angles respectively with the use of a hexagonal profiled probe. The weld strength is observed superior at the lower rotating speed of the tool but welding travel time is observed to be more. The improvement in hardness value is observed in relevance with the increase in tool rotating speed. The welding process is noticed to be productive and qualitative for the welding of aluminum and can be used for various industrial applications. |
