Stainless steel tube compounding is used before, but inevitable fine gaps between stainless steel and a steel product cannot be eliminated due to cold machining, and the steel product is rusted and fails after moisture enters the steel product from the fine gaps. According to a method for machining a steel tube through thermal compounding of stainless steel tubes and capable of preventing the steel tube from being rusted, steel is cast on a hollow wall formed by the stainless steel tubes, and fine gaps generated between each stainless steel tube and the steel tube are eliminated, so that moisture cannot enter the steel tube arranged between the stainless steel tubes, the steel tube is prevented from being rusted, and the steel tube has more compact structure and better quality.
