Why is the aluminum tube welded with stainless steel gasket ring?
Because the aluminum welding iron collapsed, so with stainless steel pad ring, can also use the aluminum ring pad with the same material
In fact, the butt welding of steel pipe, in the inner ring of the pipe with an annular gasket, the quality of welding is also a good guarantee. Argon arc welding is commonly used in aluminum alloy welding. No matter the MIG welding or by non consumable (TIG) welding, when the thickness of thin aluminum, the weld pool will because the material thickness is small and the formation of penetration, the melting temperature of aluminum is only 740 degrees, and the melting temperature of stainless steel has reached 1500 degrees, it can be a protective effect on melting the welding pool makes it easy to operate.
The welding of aluminum pipe requires great wire energy, and both sides are welded simultaneously to ensure the quality. If the pipe Jiahuan does not affect the production process, can reduce the difficulty of qualified, improve the quality and work efficiency.
