Problems solved by technology

However, this method does not disclose the detailed welding process, because argon arc welding often causes deformation, hardness reduction, sand holes, local annealing, cracking, pinholes, wear, scratches, undercuts, or bonding due to the large heat-affected zone. Insufficient force and internal stress damage, etc. The specific welding method has a great influence on the welding effect. In addition, this method still needs polishing after welding, which is easy to damage the faucet shell

Embodiment Construction

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

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

[0035] (1) Material selection: choose austenitic stainless steel 1Cr18Ni8 plate with a thickness of 2mm-3mm 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 bottom plate of the faucet shell by pressure processing. During the processing, the unevenness and dislocation of the corresponding welding positions on the body and the bottom plate should be It should be controlled within 0.3mm. When the pressure processing method cannot achieve the required unevenness and dislocation, the unevenness and dislocation of the corresponding welding positions on the body and the bottom plate should be...

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 of a faucet shell, in particular to a welding process of a stainless steel faucet shell. Background technique [0002] At present, the casting method is commonly used in the industry to produce the faucet shell, and the main material used is copper alloy or zinc alloy, which is costly. The general production process of the faucet shell is: sand core forming - sand core inspection - casting alloy smelting - chemical composition analysis - gravity casting - subsequent processing and so on. 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. At the same time, each sand casting mold can only be poured once. After the casting is obtained, the casting mold is damaged and must be recast, which greatly increases the production cost and reduces the produ...
