Stainless steel water tank and welding process thereof

Abstract

The invention relates to a stainless steel water tank and a welding process thereof. The stainless steel water tank comprises a rectangular case, wherein the top and the bottom in the case are respectively provided with multiple reinforcing plates, buffer isolation plates are fixed between the two reinforcing plates, and between the reinforcing plates and side plates of the case, and a water outlet is arranged on one side of the bottom of the case. The welding process comprises the following steps of: when a soleplate of the case and the upper side plate are welded, applying multiple wet towels on the soleplate; welding the side plates, when welding the side plates, firstly fully welding each welding line for 10-20 mm from bottom to top, and injecting a certain amount of water to the case so as to prevent the water from leaking; and welding a section while injecting the water. According to the invention, the production efficiency of the stainless steel water tank is improved, the structural stability is greatly increased, and the stainless steel water tank has stable structure and simple production process, the water leakage phenomenon of the water tank after full welding is avoided, and meanwhile, deformation of the case in a welding process and degeneration or oxidation of a plate after heating can be avoided, and the heating deformation of the board is reduced.

Description

technical field [0001] The invention relates to a stainless steel water tank and its welding process. Background technique [0002] The stainless steel water tank is a new generation of water tank products after the glass fiber reinforced plastic water tank. Its products are made of SUS304 stainless steel plate precision molding, beautiful in appearance, economical and practical, and the main body is not damaged for a long time. Compared with other water tanks, stainless steel water tank has many advantages such as light weight, high strength, corrosion resistance, high temperature resistance, clean water quality, anti-seepage, shock resistance, never moss, easy installation, no maintenance, and easy cleaning. At present, the common stainless steel water tanks include square combined water tanks, vertical cylindrical water tanks, and horizontal circular water tanks; they are made of stainless steel plates such as SUS304, SUS316L, and SUS444, and are stamped into three sizes,...

AI Technical Summary

Problems solved by technology

[0003] However, when the above-mentioned water tank is welded, the tank needs to be filled with pure water, and each weld seam must be fully welded, especially when the existing large water tank with a thickness of 2.5mm stainless steel welding L3000*W1000*H800mm, the plate is first passed through the laser The machine cuts it into pieces, and then assembles the pieces into a large water tank; the high temperature generated during full welding will cause serious deformation of the plate, which seriously affects product installation

In order to solve this problem, the general manufacturers will use some wet towels for cooling treatment, but wet towels are used during the overall welding, and the deformation will be confirmed after welding. Products with serious deformation will be reshaped by flame heating, so the plastic effect is poor. The plate is easy to deteriorate or oxidize after heating

[0004] Moreover, the existing water tank has a complex structure, low structural strength and poor stability, and is prone to deformation during use or welding, which affects the use and quality of the product
