| Abstract: | Combining the principle of high-frequency welding with the characteristics of aluminum product as welded pipe blank, the features of melting point, thermal conductivity, melting heat, specific heat capacity, permeability, high-temperature color change, high-temperature strength, oxygen affinity and current penetration depth of aluminum tube blank in high-frequency welding and their influences on high-frequency aluminum tube welding were systematically expounded. It is pointed out that the welding time can be shortened by reducing the outer diameter of welding and increasing the frequency of welding current, and the effect of reducing the outer diameter of welding squeeze roller is the most obvious. |
