------------------------------------------------------------------------------***-----------------------------------------------------------------------Abstract: Shielded Metal Arc welding with ENiCrMo-10 weld cladding on Grade 316L austenitic stainless steel is examined in this article. This material-process combination is being evaluated for use in petrochemicals, oil, gas, medicines, and chemical processing plants. The weld cladding was assessed through a series of examinations, counting visual inspection, micro hardness, chemical composition study via optical spectroscopy, bend tests and Corrosion resistance testing, while macro and microstructure observations provided additional insights. These observations show numerous remarkable results. A large dilution height of 3.0 mm from the base metal enabled precise control and minimum alloy mixing. Visual inspection and bend tests confirmed cladding weld integrity. The weld cladding's high-quality finish eliminates the need for costly machining and polishing, saving money. The study clarifies main and secondary inter-laminar spacing, improving structural integrity. Weld cladding toughness is also good. The weld cladding's low corrosion resistance must be noted. This research introduces a new material combination and highlights its many benefits for industry stakeholders, notably in the petrochemical and pharmaceutical industries. It improves welding operations and improves industrial applications' efficiency, cost, and structural performance.

Introduction: The manufacturing industries like chemical, petrochemical, pharmaceutical and oil & gas play a important role in the world economy. They supply variety of materials and products related to chemicals are necessary for numerous region, including energy, manufacturing, and transportation [1]. A major challenge for industries is the corrosive degradation of equipment surfaces. This problem is triggered by wear and corrosive substances that contaminate various parts of manufacturing equipment [2][3]. Degradation can result from erosion, corrosion, or / and friction, either independently or in combination, and is influenced by parameters. To address this issues, a practical preventive measure includes applying protective coatings made from specialized corrosion-resistant materials, considerably reducing degradation of manufacturing equipment [4]–[9]. Responding to rising requirement for surface protecting materials across a variety of applications necessitates inventive resolutions that enhance material life, efficiency, and consistency. So, selecting appropriate protective layers becomes important for ensuring safe operations. Among the effective methods garnering considerable attention are weld cladding techniques, which improve corrosion resistance of parent materials [10], [11]. Weld cladding, a specific technique for enhancing corrosion resistance, plays a important role in safeguarding critical infrastructure and equipment from aggressive environments. This process entails depositing a layer of corrosion-resistant alloy onto a base metal through welding. The primary benefit of this method lies in its capacity to create a protective coating that insulates the underlying material from corrosive agents, including acids, chemicals, and saltwater. By employing weld cladding, industries can significantly extend the operational life of their assets, thereby reducing the frequency of replacements and minimizing maintenance requirements. This technique offers a strategic approach to corrosion prevention, allowing for the targeted application of protective materials to high-risk areas. As a result, it presents a more economical alternative to constructing entire structures from costly corrosion-resistant alloys. The implementation of weld cladding techniques contributes substantially to the overall resilience, longevity, and economic efficiency of industrial equipment and
