Problems solved by technology

[0002] With the improvement of people's living standards, the demand for high-grade stainless steel pots, pans and other double-bottomed containers is increasing. Traditional stainless steel double-bottomed containers are brazed by a stainless steel container base, an aluminum sheet inside, and a stainless steel bottom clad or made of stainless steel containers. The base body, the inner copper sheet, and the stainless steel clad bottom are brazed. The problem is: after the stainless steel vessel base of the traditional stainless steel double bottom vessel is brazed with the stainless steel clad bottom layer, there are unconnected seams, which are not beautiful, such as the product Dry burning at about 450-500°C, the welding position between the product and the bottom will fall off naturally, and the unconnected seams are easy to accumulate dirt and breed bacteria
