Title:
WASTE LIQUID TREATMENT TANK AND MACHINING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/253007
Kind Code:
A1
Abstract:
Disclosed is a waste liquid treatment tank, comprising an inner tank body (8) and an outer tank body (6). The inner tank body (8) is made of a corrosion-resistant metal material; the outer tank body (6) is made of a common metal material; and the inner tank body (8) and the outer tank body (6) are formed into a whole by means of friction stir welding. The waste liquid treatment tank is formed by friction stir welding of two layers of different materials, such that machining costs are reduced, the machining difficulty is reduced, automated machining can be realized, and the production efficiency is improved.
