Determination of optimum welding parameters in connecting high alloyed X53CrMnNiN219 and X45CrSi93 steels by friction welding

Abstract

In this study, different welding parameters were applied to two different steels with high alloys and mechanical and metallographical investigations are performed. Thus, the optimum welding parameters were determined for these materials and working conditions. 12⋅30 diameter steel bars made up of 1⋅4871 (X53CrMnNiN219) and 1⋅4718 (X45CrSi93) steel were used as experimental material. The material loss increased with increase in friction and rotating pressure. No fracture at the welding region was observed and the highest fracture energy was identified in B5 group. Based on micro hardness investigation; the hardness profile reached its minimum value at the welding region.

Pengaruh Waktu dan Tekanan Gesek terhadap Kekuatan Tarik Sambungan Paduan Aluminium dan Baja Karbon pada Pengelasan Gesek Continuous Drive

“…Penyambungan aluminium dan baja dapat dilakukan, dengan menggunakan pengikatan mekanis (mechanical fastening), dan juga menggunakan pengikatan adesif (adhesive bonding). Kedua metode pengikatan ini memiliki keterbatasan pada kekuatan spesifik sambungan dan juga geometri pada daerah sambungan, seperti harus adanya bentuk pangkuan sambungan (lap geometry) yang cukup luas [3]. Metode lainnya adalah metode pengelasan, yang dapat dibedakan menjadi pengelasan fusi dan pengelasan solidstate.…”

Evaluation of tensile strength and fracture behavior of friction welded dissimilar steels under different rotational speeds and axial pressures

“…The joining has increasingly been used in the materials technology because of the materials having different mechanical properties needs to be efficiently and effectively joined to increase their performance (Uzkut et al 2011). Welding is one of the fast growing principal technologies used for joining materials which is almost used by all the fabricating industries.…”
