Welding is for two or more parts heat; pressure or Linking is a fabrication process cooling of parts. Welding usually involves metals and Used in thermoplastics, but also in wood can be used. A finished welded joint May be referred to as good material. Welding such as metals, thermoplastics, and/or wood Applying heat or pressure to materials It is a process of joining them together. Cool those down Allow enable the connection. Different Processes and techniques unique to materials required there are some people items that are considered unusable. MIG welding uses an electrode wire and shield gas fed continuously through A lamp held in the hand. A consumable for TIG welding is tungsten uses an electrode, which is a supply line, and Shield through a separate, hand-held filler wire manually injected into the weld pool with gas. Research significance: Welding is two or more parts by heat, pressure, or both together Linking is a fabrication process. Welding is usually in metals and thermoplastics used, but can also be used on wood. The finished welded joint may be referred to as a weld meant. Gas pressure welding joins two base materials in under pressure by heating them with gas contact. Resistance spot welding two Combine the basic ingredients together heating up with heat generated by electrical resistance by conducting current. The basic purpose of welding is within a solid joint combining two elements. Welders in general Work with metal or thermoplastic and durable filler material to hold together are using Skyscrapers in our world, many modern ones like cars, ships, and planes Welding is used to make structures. Mythology: Alternative: Factorial designs, ANNs, GA, and RSM. Evaluation Option: Computational time, Experimental domain, Model developing, Availability in software, Optimization Accuracy level. Result: from the result it is seen that Model developing and is got the first rank whereas is the Availability in software got is having the lowest rank. Conclusion: The value of the dataset for Welding Process in Fuzzy TOPSIS method shows that it results in Model developing and top ranking.
