“…It is during this stage that the two materials are plasticized (become malleable). The green line indicates measurement of "length loss" and the stopping point when the part reaches planned overall length (Fukumoto et al, 1999;Akata and Sahin, 2003;Sahin and Akata, 2003;Kalsi and Sharma, 2011;Leslie and Sasidharan, 2016;Sarsilmaz et al, 2017;Meisnar et al, 2017).…”

Purpose Nowadays, a rotary friction welding method is accepted in many industries, particularly for joining dissimilar materials as a mass production process. It is due to advantages like less material waste, low production time and low energy expenditure. The effect of the change in carbon contents in steel is studied experimentally in the rotary friction welding process, and a statistical model is developed. The Grey Taguchi method gives the single parameters optimization for all output responses. The paper aims to discuss these issues. Design/methodology/approach An experimental setup was designed and produced to achieve the multi-response in single optimum parameters through Grey relational analysis. A continuous/direct drive rotary friction welding process is chosen in which transition from friction to the forging stage can be achieved automatically by applying a break. In this experimentation, high carbon and low carbon work-pieces with different carbon percentage were welded with rotary friction welding. Response tensile strength and micro-hardness of the design of the experiment are used to analyze the results. Findings The optimization of parameters has been performed with Grey relational analysis, and optimum parameters are friction pressure 40 kg/cm2, forging pressure 100 kg/cm2 and speed 1,120 rpm. GRA optimum parameters give 56.04 and 82.16 percent improvement in Tensile strength and micro-hardness, respectively. Practical implications High carbon steel (En-31) and low carbon steel (SAE-1020) are used in so many industrial applications. These materials are mostly used in the process like manufacturing, metallurgy, machinery, agricultural, etc. These practical applications have brought forward definite and notable economic benefits. Originality/value It provides a new framework to investigate the problems where multiple input machining variables and various output responses are obtained in single optimized parameters.

“…The most extreme impact durability estimations of 25J and 20J both for charpy and izod were accessible at 75Megapascal and with the expansion in axial stress, the hardness at the focal point of weld cross-segment increments and most extreme hardness was seen at 135Megapascal. Sarsilmaz et al [15] had investigated the properties of friction welded joint of Armor 500 steel and duplex steel AISI 2205 (ferritic/austenitic). The considered variable variables are rubbing time (4, 6, 8 sec), friction stress (60, 80 Megapascal) and fixed variables such as spindle speed (1800 rpm), forging time (6sec) and forging stress (120 Megapascal).…”

Friction welding (FW) is a solid state welding method invented in 1940s by the welding institute. Without genuine liquefying of the materials, a normally excellent weld joint is produced with this procedure. The method is quick, environment friendly and easy to carry out. The extent of the present examination is to assess the effect of welding variables on the tensile properties of friction welded of dissimilar metals. From this review study, posted research papers of different authors has been studied and it has been determined that the welding variables like revolution pace, rubbing time , friction stress, forge time, forge strain are have high impact on the mechanical properties of friction welded joints. Finally, the conclusions of the review study presented the practical applications for the manufacturing sector and proposals for further innovative work and advancements. The purpose for this article is to advise industry and the scholarly world regarding the advantages of rotary FW so the procedure might be used in better way.

“…Industrial robots have wide applications due to their ability to perform operations quickly, repeatedly and accurately. Process flexibility and the possibility of welding in various positions are the main reasons for using robots [22]. Therefore, the run trajectory and the position of a gun relative to the weld axis must be maintained accurately.…”

The purpose of this study is to examine the projectile penetration resistance of the base metal and heat-affected zones of armor steel weldments. To ensure the proper quality of armor steel welded joints and associated ballistic protection, it is important to find the optimum heat input for armor steel welding. A total of two armor steel weldments made at heat inputs of 1.29 kJ/mm and 1.55 kJ/mm were tested for ballistic protection performance. The GMAW welding carried out employing a robot-controlled process. Owing to a higher ballistic limit, the heat-affected zone (HAZ) of the 1.29 kJ/mm weldment was found to be more resistant to projectile penetration than that of the 1.55 kJ/mm weldment. The ballistic performance of the weldments was determined by analyzing the microstructure of weldment heat-affected zones, the hardness gradients across the weldments and the thermal history of the welding heat inputs considered. The result showed that the ballistic resistance of heat affected zone exist as the heat input was decreased on 1.29 kJ/mm. It was found that 1.55 kJ/mm does not have ballistic resistance.
