PREAMBLE TO THE DESCRIPTION
COMPLETE
The following specification particularly describes the invention and the manner in which it is to be performed:

FIELD OF THE INVENTION:-
The present invention relates to a novel process for manufacturing of stainless steel vessel.
BACKGROUND OF THE INVENTION:
Traditionally the manufacturers of Stainless Steel pot employ a very primitive method for manufacturing stainless steel pot {matka). In this primitive method the two parts i.e. lower part and upper part of pot are joined with each other. The joint generally lies in the middle .-of the pot, and is affixed with carbide gas weldingwhich utilizes acetylene gas which is used.in the form of cylinder gas for metal fabrication and construction.
The biggest flaw of the method is the joint affixed is weak and loosen up after a period of use of pot, In addition the affixing of the joint utilizes iron flier wires, which after a period of use get corroded making pot unsuitable for domestic use. Further the primitive method is expensive resulting in high cost of the end product.
. Considering the disadvantage of the primitive method there is need of an alternative method for manufacturing Stainless Steel pot.
SUMMARY
The embodiment of the present invention contemplates to a method of manufacturing stainless steel pot (matka) called SUPOWA comprising following steps A) embossing an interlocking ring on the upper part of the pot which assists in attaching the lower part of the pot to the upper part. B) Thereafter both upper and lower part are interlocked, the interlocked pot is stitched at the mid joint with the help of spot welding machine. C) The mid joint is further bolster with the help of automatic seam welding. D) The mid joint interlocking is suppressed so that no joint is visible in the final product.
The major advantage of SUPOWA method is that there is no use of carbide, LPG, Diesel, Kerosene, Petrol like material in fixing the joint as a result the final product or pot is more

Hygienic. The joint formed is very strong and the stainless steel p.ot has long life, and leakage proof. Further, there is no use of-iron wire due to which the.final product is corrosion free and Hygienic.

DETAILED DESCRIPTION
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
Traditionally the manufacturers of Stainless Steel pot do employ a very primitive method for manufacturing stainless steel pot (matka). In the primitive method the two parts i.e. lower part and upper part of the pot are joined with each other. The joint generally lies in the middle of the pot, and is affixed with carbide gas welding which utilizes acetylene gas which is used in the form of cylinder gas for metal fabrication and construction.
Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between carbon and hydrogen atoms. This

energy is then released and utilized in different ways by our customers for a variety of industrial purposes.
Among these many uses of acetylene gas, the largest and perhaps the most familiar is its use in. the form of cylinder gas for metal fabrication and construction. When combined with oxygen in an oxyacetylene torch, acetylene produces a flame temperature in excess of 6,000F, the hottest flame of all hydrocarbon gases. This provides the means to cut or join many types of metal, cleanse them" of surface imperfections, and strengthen them through flame hardening. In addition, acetylene is lighter than air and is therefore the safest fiiel gas to use in confined spaces, below ground, or on ships.
The biggest flaw of the method is the joint affixed is weak and loosen up after a period of use of pot. In addition the affixing of the joint does utilizes iron filer wires, which after a period of use get corroded making pot unsuitable for domestic use. Further the primitive method is expensive resulting in high cost of the end product.
In the present invention a new method for manufacturing stainless steel pot (matka) called SUPOWA is defined. In this method first of all lower part (shown in figure 2) and upper . part (shown in figure 1) of stainless steel are considered. On the upper part an interlocking ring is embossed (shown in figure 3) so that the two parts can fix with each other. The joining of two parts which give rise to a pot like structure (shown in figure 4) which is later stitched at the centre with the help of spot welding {shown in figure 5). The strength of the mid joint is further enhanced with the help of automatic seam welding. The mid joint interlocking is suppressed so that no joint is visible in the final product (shown in figure 6).
Spot welding which is used here is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.12 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in

a very short time (approximately ten-one hundred milliseconds). That permits the welding to occur without excessive heating of the remainder of the sheet
The major advantage of SUPOWA method is that there is no use of carbide, LPG, Diesel, Kerosene, Petrol like material in fixing the joint as a result the final product or pot is more Hygienic. The joint formed is very strong and the stainless steel pot has long life and leakage proof. Further, there is no use of iron wire due to which the final product is corrosion free and Hygienic.

It will be appreciated that several of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Also that various presently unforeseen or unanticipated alternatives, modifications variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims

In the foregoing specification, the invention is described with reference to specific embodiments thereof, but those skilled in the art-will recognize.that the invention is not limited thereto. Various features and aspects of the above-described invention may be used individually or jointly.' Further, the invention can be utilized in any number of environments and applications beyond those described herein without departing from the broader spirit and scope of the specification. The specification and drawings are, accordingly, to be regarded as illustrative rather than restrictive. It-will be recognized that -the terms "comprising," "including," and "having," as used.herein, are specifically intended to be read as open-ended terms of art.
