Optimization of welding process parameters These welding parameters are welding current, welding voltage, gas flow rate, wire feed rate, etc. They affect welding strength, weld pool geometry of steel material during welding. By using the DOE method, the parameters can be optimized and have the best combination of parameters for the target quality. The VIKOR (VIšekriterijumsko Kompromisno Rangiranje) Optimal replacement Select method is used Biomass product, Catalyst, Solvent, Temperature/ K. in Evaluation. Alternatives Wood, Bio-oil, Lignin, Glucose, Saccharine is the Best and Worst Value. Saccharides is got the first rank whereas is the Glucose is having the Lowest rank. Keywords: Wood, Bio-oil, Ligni, Glucose, Saccharides, Biomass product, Catalyst, Solvent, Temperature/ K, SPSS Method. 1. INTRODUCTION Common affect the required output welding Process parameters process Welding speed, arc voltage, welding current etc length of arc, angle, handling, speed. A variety of selected Weld for welding processes Process parameters vary. These welding parameters are welding current, welding voltage, gas flow rate, wire feed rate, welding strength; steel during material Weld pool geometry Affects method, parameters Use it for optimization and target quality May have a better mix. The top welding parameters to consider during arc welding are: amperage, voltage and wire feed speed. In most welding processes, if these welding parameters are not set correctly, all of them can affect the finished weld, P number, F number, a number PWHT, thickness (outside the specified range) is an essential variable in the welding process specification. the VIKOR approach is complex. Developed to optimize more than one standards system. This is a compromise ranking list by preliminary (given) weights Also determines the compromise response obtained. This approach, ranking and specializes in determining from it hard and fast in the presence of contradiction Alternatives standards. 2. OPTIMIZATION OF WELDING PROCESS PARAMETERS Welding process parameters Necessary of penetration to reach depth and HAZ width. According to the design matrix suggested by RSM Bead on plate welding tests were carried out. Numerical and graphical optimization using RSM Required depth of penetration and desired HAZ width Gets the attitude. of the GA-based model Process using generated data for development with parameters Weld bead shape parameters First multiple regression models for correlation were created. Then regression models are optimized In GA to determine the process parameters were used. In a GA-based model, the elec the process is different and their performance evaluation is done. The models suggested several solutions and Through tests of identified solutions Verified. Performances of models later 9Cr-1Mo A-TIG welding process for steel parameters were compared to optimize [23]. Welding process parameters are more available Beneficial welding pool geometry Generally, preferred welding process parameters decided empirically or from a mentor. However, selected Welding technique parameters specific welding the gold standard for gadgets and the environment or superior weld pool geometry It does not guarantee that it can be created. Ultimate weld pool geometry is mentioned [25]. The pulsed GTAW process is lean and mean for bonding with thick materials Appropriately, A. G. Stainless steel sheets and weld metal Metallurgical manipulation of important compositions Mechanized welding, welding process of parameters and welding with advanced usage the choice of process is to be more specific Need, accurate fine weld bead parameters Minimum charge and excess again Make sure that repeats are done. [27]. They have a look at simplest analyzed that the purpose of
