“…FR-1 and FR-2 can withstand about 520°C -570°C [36], these materials are also not sufficient to with fire. Cast austinite stainless steel can withstand up to 400°C [37], these is also not sufficient. Moving to the ultimate tensile strength Q420 stainless steel has tensile strength up to 420Mpa [38], High strength steels Q460 & Q690 can withstand up to 600°C and it has the ability to regain 67% of their initial ultimate strength [39], these Q420, Q460, Q690 materials can be used as it has the thermal resistivity and ultimate tensile strength that is required.…”

Nowadays robots are used for various purpose in various fields. From use of pick and place in big industries to cleaning of house they are nowadays use everywhere. As they work fast give precise result and most importantly reduces human effort. Human may make mistake but robots don't they work as per the input given to them. Mostly robots are used in huge industries, Hospitals, Factories, Defence, etc. They can also be used to perform dangerous and difficult operations. Extinguishing fire is one part of that, it is important to extinguish or control huge fire to some extent till the fire truck arrives. This fire can be anywhere at home, office, school/college, etc. Extinguishing fire without any injury to human is one of the major problems in today's world. Robots can be used for that purpose too with proper component and material selection, but the materials that used for making these types of robots must have some fire and thermal resistivity property in it. In this paper proper review of various components and material is done. Also, which type of material must be used for fire extinguishing purpose is also mentioned in this paper. The selection of proper Component and material selection for a firefighting robot are provided in details.

The dissimilar butt welding of nickel 201 and AISI 316 was studied by utilising a 4 kW CO 2 laser with the help of Response Surface Methodology (RSM). The effects of laser power are 2580-3420 W; welding speed 450-1150 mm/s; focal position -1 to 0 mm; beam angle 84-96 degrees; and beam offset 0-0.2 mm on weld geometry, i.e., depth of penetration, bead width, and the Fusion Zone Area (FZ). The required weld profile responses for dissimilar butt welding were modeled mathematically. The constructed models were tested using the sequential F-test, lack of fit test, and analysis of variance (ANOVA). Mathematical models are reflected in the output answers within the parameters of the input process. This laser welding process with an optimal condition zone was discovered using a numeric optimization technique. It aids in the optimization of this process's regulated responses by allowing for more effective parameter combinations. It is clear from the tensile test results that the expected weld strength has been achieved. There is some delta ferrite found in the interdendritic zone in the microstructure and the solidification process reveals columnar grains.

“…On the other hand, ERNiCrMo-4 filler electrode weldments exhibited superior toughness and ductility. Madhankumar et al [11] performed the dissimilar laser butt welding of Inconel 718 and DSS 2205 with varying parameters and concluded that the tensile strength is a function of laser power, welding speed and focal position.…”

In demanding applications, maintaining structural integrity in dissimilar welded joints like those between duplex stainless steel and Ni-based superalloys requires achieving the best possible mechanical properties. This work examines the impact of post-weld heat treatment (PWHT) on the mechanical characteristics of joints made via double-sided tungsten inert gas (TIG) welding. The dissimilar welded joint was investigated by exposing it to the PWHT for 12 h at 650 °C. Reducing the negative impact of heat generated by welding on the mechanical characteristics and microstructure of the fusion zone was the main goal. To study for changes in the microstructure before and after PWHT, optical microscopy and scanning electron microscopy methods were used for microstructural analysis. To determine the effect of PWHT on the welded joints, mechanical properties such as tensile strength, toughness, and ductility were also assessed. The mechanical properties showed significantly enhanced characteristics and refined grain structures in the fusion zone.
