Stainless steel water faucet shell welding technology

Abstract

The invention relates to a water faucet shell production technology, in particular to a stainless steel water faucet shell welding technology. The stainless steel water faucet shell welding technology comprises the following steps of material selection, part preparation, cleaning before welding, part clamping, part welding and post-welding checking. In the part clamping process, a welding clamp needs to be adjusted so that a welding position of a base plate can be embedded in a welding position of a body. A laser penetration fusion welding method is adopted for part welding. Due to the facts that the welding position of the base plate is embedded in the welding position of the body, and the body and the base plate are welded together through the laser penetration fusion welding method which is highly centralized in energy density, weld strength of weld joints is high, and the weld joints are compact and beautiful in appearance.

Description

technical field

[0001] The invention relates to a production process for a faucet shell, in particular to a welding process for a stainless steel faucet shell. Background technique

[0002] At present, the industry generally adopts the method of casting to produce the faucet shell, and the main material used is copper alloy or zinc alloy, and the cost is relatively high. The production process of the general faucet shell is: sand core forming-sand core inspection-casting alloy melting-chemical composition analysis-gravity casting-subsequent processing, etc. However, due to the overall soft and porous nature of the sand, the dimensional accuracy of the casting is low, and the surface is also rough and prone to defects, which makes the forming quality of the faucet poor. Simultaneously, each sandy mold can only be poured once, and the mold is damaged after obtaining the casting, and must be recast, which greatly increases the production cost and reduces the production efficie...

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] The stainless steel faucet housing welding process of this implementation includes the following steps:

[0035] (1) Material selection: Austenitic stainless steel 1Cr18Ni8 plate with a thickness of 2mm-3mm is selected as the material, and the specific plate thickness can be selected according to actual needs.

[0036] (2) Parts preparation: The austenitic stainless steel 1Cr18Ni8 plate is made into the body and the bottom plate of the faucet shell respectively by means of pressure processing. During the processing, the unevenness and dislocation of the corresponding welding positions on the body and the bottom plate should be Control within 0.3mm. When the pressure processing method cannot achieve the required unevenness and misalignment, machining should be used to control the unevenness and misalignment of the corresponding welding po...
