a first welded joint disposed between the first body portion and the second body portion and extending in a direction parallel to a direction in which water flows through the faucet; and a second welded joint disposed between the first body portion and the second body portion opposite the first welded joint and extending continuously along a distance of an edge of the first body portion, wherein the edge of the first body portion extends between the first base portion and the first upper portion of the first body portion, and wherein the first upper portion is disposed above the first spout portion and the second upper portion is disposed above the second spout portion. ### Claim 2 (depends on 1) The faucet body of claim 1, wherein the first and second faucet body portions are symmetrical halves of the faucet body. ### Claim 3 (depends on 2) The faucet body of claim 2, wherein the first and second spout portions define an opening at which water exits the faucet, wherein the first welded joint includes portions on both sides of the opening. ### Claim 4 (depends on 1) The faucet body of claim 1, wherein the first and second faucet body portions are each constructed from single sheets of stamped sheet metal material having a thickness of approximately 1 to 2 mm. ### Claim 5 (depends on 1) The faucet body of claim 1, wherein the first welded joint lies in the same plane as the second welded joint. ### Claim 6 (depends on 1) The faucet body of claim 1, wherein the first welded joint extends continuously along the entirety of the first distance, wherein the second welded joint extends continuously along the entirety of the second distance. ### Claim 7 A method, comprising: causing a first stamped faucet portion to be manufactured from a first sheet of material, the first faucet portion defining a first edge extending a distance between a base and a spout; causing a second stamped faucet portion to be manufactured from a second sheet of material, the second faucet portion defining a second edge extending the distance; causing the first edge of the first faucet portion to be held against the second edge of the second faucet portion by a holding apparatus; causing the first edge of the first faucet portion to be welded to the second edge of the second faucet portion by a laser welding apparatus to form a welded joint extending along the distance, the laser welding apparatus including a laser configured to emit an optical beam along an optical path and a rotatable optical element configured to alter the path of the optical beam towards the first faucet portion and the second faucet portion to form the welded joint; causing the welded joint to be ground to form a faucet body; and causing the faucet body to be made available to a user. ### Claim 8 (depends on 7) The method of claim 7, wherein causing the first faucet portion to be manufactured includes: causing a first sheet of material to be positioned between a first die set of a first stamping press including a female component and a male component, the female and male components including portions having surfaces that correspond to an outer surface of the first faucet portion; causing the first stamping press to press the male component into the female component such that the first sheet of material includes a first portion of having a surface corresponding to the outer surface of the first faucet portion and a second portion; and causing the second portion of the first sheet of material to be removed. ### Claim 9 (depends on 8) The method of claim 8, wherein causing the second faucet portion to be manufactured includes: causing a second sheet of material to be positioned between the first die set of the first stamping press; causing the first stamping press to press the male component into the female component such that the second sheet of material includes first portion having a surface corresponding to the outer surface of the second faucet portion and a second portion; and causing the second portion of the second sheet of material to be removed. ### Claim 10 (depends on 9) The method of claim 9, wherein causing the second portion of the second sheet of material to be removed is performed via a laser cutting apparatus. ### Claim 11 (depends on 9) The method of claim 9, wherein the first and second sheets of material are constructed of sheet metal. ### Claim 12 (depends on 9) The method of claim 9, wherein the first and second sheets of material have thicknesses of approximately 1 to 2 mm. ### Claim 13 (depends on 8) The method of claim 8, wherein causing the second faucet portion to be manufactured: causing a second sheet of material to be positioned between a second die set of a second stamping press including a female component and a male component, the female and male components including portions having surfaces that correspond to an outer surface of the second faucet portion, wherein the second die set is different from the first die set; causing the second stamping press to press the second male component into the second female component such that the second sheet of material includes first portion having a surface corresponding to the outer surface of the second faucet portion and a second portion; and causing the second portion of the second sheet of material to be removed. ### Claim 14 (depends on 7) The method of claim 7, further comprising causing a support bracket to be attached, the support bracket configured to hold an additional faucet component to a combination of the first and second faucet portions, the additional faucet component at least one of a cartridge and a fixing hose. ### Claim 15 (depends on 14) The method of claim 14, wherein the support bracket is attached by the laser welding apparatus. ### Claim 16 (depends on 7) The method of claim 7, wherein first faucet portion defines a third edge and the second faucet portion defines a fourth edge, the method further comprising causing the third edge of the first faucet portion to be welded to the fourth edge of the second faucet portion by the laser welding apparatus to form a second welded joint. ### Claim 17 (depends on 16) The method of claim 16, wherein the first and second welded joints are substantially parallel to one another. ### Claim 18 (depends on 7) The method of claim 7, wherein the first and second faucet portions are symmetrical halves of the faucet body. ### Claim 19 (depends on 7) The method of claim 7, further comprising causing a coating to be applied to the first and second portions such that the coating covers the welded joint, the coating applied by at least one of a physical vapor deposition process or an electroplating process. ### Claim 20 A thin-walled faucet body for a faucet, comprising: a first sheet of stamped material that defines a first faucet body portion having a thickness between about one millimeter and two millimeters, the first faucet body portion including a first base portion and a first upper portion each extending in a first direction, and a first spout portion extending in a second direction at an angle to the first direction; a second sheet of stamped material that defines a second body portion having a thickness between about one millimeter and two millimeters, the second faucet body portion including a second base portion and a second upper portion each extending in the first direction, and a second spout portion extending in the second direction at the angle to the first direction; a first welded joint disposed between the first body portion and the second body portion and extending in a direction parallel to a direction in which water flows through the faucet; and a second welded joint disposed between the first body portion and the second body portion opposite the first welded joint and extending continuously along a distance of an edge of the first body portion, wherein the edge of the first body portion extends between the first base portion and the first upper portion of the first body portion, and wherein the first upper portion is disposed above the first spout portion and the second upper portion is disposed above the second spout portion.
