d. Welding and fixing the joint part;
as shown in fig. 7 and 8, the joints of the upper edge portions 171 of the rear flap 17 and the corresponding lower edge portions 161 of the front flap 16 are welded and fixed, and the joints of the upper corner edge portions 172 of the rear flap 17 and the corresponding lower corner edge portions 131 are welded and fixed, so that the front flap 16 and the rear flap 17 are welded and fixed to each other to form a water outlet pipe portion 18 extending in the transverse direction, and a socket 181 can be formed at the end of the water outlet pipe portion 18, and in this embodiment, the angle between the socket 181 and the bottom opening 12 can be between 30 degrees and 165 degrees.
e. Machining and molding a valve mounting hole;

However, if the valve seat 20 is designed to be directly mounted to the valve mounting hole 141 from above the valve mounting hole 141, the welding step f of the valve seat 20 and the welding step h of the base 40 are not limited by priority, and may be selected or determined by an operator according to circumstances.
In this embodiment, the process of bending and welding the faucet body 1 with the stainless steel tube further includes a surface treatment step i, which is performed after the welding steps of the valve seat 20, the water outlet 30, and the base 40, i.e., the welding step f, the welding step g, and the welding step h, are completed.

A slot 163 is further cut at each notch 162 of the front flap 16 to facilitate bending of the front flap 16.
As shown in fig. 15, in the present embodiment, the slots formed by the left and right side walls extend to the wall thickness t1 of the rear side wall at the junction of each upper corner flange 172 and each opposite lower corner flange 131 of the rear flap 17, and the notches 162 at the junction of each lower flange 161 and each opposite lower corner flange 131 of the front flap 16 also extend to the wall thickness t2 of the front side wall, so that the arc angle of the front flap 16 and the rear flap 17 at the junction can be minimized, which facilitates the bending on the one hand, and reduces the weld bead to avoid poor welding on the other hand.
As shown in fig. 16, the faucet body 1 completed through the above steps can be mounted with an operating handle 3 on the valve seat 20, a water wave generator 4 at the water outlet member 30, a water supply pipe set 5 at the bottom end of the valve seat 20, and a locking assembly 6 fixed on a table 7, thereby completing the mounting operation of a faucet 2, particularly a square faucet 2.

The forming method has the advantages of simple integral structure, relatively simple forming process, no need of complex machining process, simple manufacturing procedures of cutting, slotting, bending, welding and the like, low material cost and high production efficiency. The stainless steel material also meets the requirements of environmental protection and no lead, and has long service life.
While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various alternatives and modifications can be made therein in light of the above teachings; accordingly, all such alternatives and modifications as may be devised based on the disclosure herein are intended to be included within the spirit and scope of the present claims.
