10.Material: aluminum 1070;For Q235B steel
As a new welding process, it can weld all kinds of metals with different strength, different expansion coefficient and different properties, saving precious metals, making it easy to combine and match the properties of lamination materials and base materials, widely used in electrolytic aluminum industry and metallurgy industry.
Applications: electrolytic aluminum, chemical fertilizer, transition joint, naval vessel, aerospace, instrumentation, cryogenic engineering, etc.
