In some preferred embodiments, the weld extends in a radial direction of the body.

In some preferred embodiments, a protective gas is continuously introduced into the body during the welding of the first nesting site and the second nesting site.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses establish first cover and establish position and second cover and establish one of the two cover in the two another surface to the wall thickness design that establishes position outside with the cover is less than welding penetration H, and the welding can pierce through the cover and establish position outside like this, thereby can effectively avoid the two problem that contact part exists the gap, and the welding is more fully reliable, and welding strength is better.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 3 and 5, an embodiment of the present invention provides a faucet, which includes a hollow body 10 and a joint 20 disposed at one end of the body 10, wherein one end of the joint 20 is formed with a first set of installation portions 21 sleeved with the end of the body 10, and the second set of installation portions 11 is disposed in an area of the body 10 corresponding to the first set of installation portions 21. The first nesting portion 21 and the second nesting portion 11 are welded together by a continuous laser welder to form a weld 30, and the weld 30 has a weld penetration H (see fig. 4). The first set of wall thickness of establishing position 21 and the second set and establishing one of the position 11 is less than welding penetration H, and overlaps and establish the surface of the other of the two, that is, the first set is established the position 21 and is established the wall thickness that the position was established outside to the cover in the second set of position 11 and be less than welding penetration H, and the welding can pierce through the position of establishing outside like this to can effectively avoid the two contact position to have the problem in gap, the welding is more abundant reliable, and welding strength is better.

In this embodiment, the first nesting portion 21 is nested in the second nesting portion 11, the welding penetration H is greater than 1mm, and the wall thickness of the second nesting portion 11 is between 0.5 mm and 0.9 mm. It is further preferred that the wall thickness of the second nesting portion 11 is between 0.8 mm and 0.9 mm. In other embodiments, the second nesting portion 11 may be sleeved in the first nesting portion 21, and at this time, the corresponding, preferable design welding penetration H is greater than 1mm, the wall thickness of the first nesting portion 21 is between 0.5 mm and 0.9 mm, and further preferably, the wall thickness of the first nesting portion 21 is between 0.8 mm and 0.9 mm.

In this embodiment, in order to ensure the self-strength of the body 10, the wall thickness of the body 10 except the second nesting portion 11 is greater than 1mm.

In this embodiment, referring to fig. 5, a step surface 22 is formed on an outer surface of the joint 20, when the first sleeving portion 21 is sleeved in the second sleeving portion 11, an end surface of the second sleeving portion 11 abuts against the step surface 22, and a welding portion 30 having a welding penetration H is formed by welding at the abutting position, wherein the welding portion 30 extends along a radial direction of the body 10.

In this embodiment, in order to prevent the first nesting portion 21 and the second nesting portion 11 from being oxidized during the welding process, a protective gas, such as nitrogen (N2), argon (Ar), helium (He), etc., is continuously introduced into the body 10.

In this embodiment, a joint 20 is welded to each of the inlet and outlet ends of the faucet body 10.
