Improvement of microhardness property by novel hash pattern welding of EN10083 steel compared to present technique of friction welding.

In order to improve microhardness qualities, the article compares the traditional friction welding approach with the innovative hash pattern friction welding of EN 10083 steel. In total, two groups commercial and hash pattern friction welding were used in the study. There are sixteen pieces of work in each category. The dimension of the material is 30 mm in diameter and 60 mm in length. It is then welded by a CNC machine with care, and the micro-Vickers hardness tester is used to specify the microhardness of it. This process has a G power of 80%, and the sample size is calculated using α = 0.05 per set and the total sample size calculated is 32. Time, temperature, frictional force, and spindle speed are taken into consideration for results that have Z-pattern friction welding or commercial friction welding with increased microhardness. Between two groups, there were statistically significant differences since the significant value of p=0.000 (2-tailed), which is less than (P<0.05). The hash pattern friction welding has a 5.6% higher microhardness than standard friction welding (571>539) HV. Because of the increased frictional temperature caused by the pattern in the workpiece, the metallurgical bonding was strong enough to have greater Microhardness. The results of this experiment indicate that, although commercial friction welding has a Vickers hardness of 539 HV at 1400 rpm, 5.5ton, 4mm depth of penetration, and 25 seconds, hash pattern friction welding's hardness of 571 HV.
