Physical properties of aluminum and stainless steel pipes and stainless steel tube aluminum high frequency induction welding biggest problem is the impact oxides. 1) aluminum easily oxidized to Al2O3, melting point up to 2050 ℃ professional production of finely drawn aluminum rod manufacturers, and aluminum's melting point is 658 ℃, the welding, the oxide film prevents the molten metal fusion bonded mother Shandong fine pull rod, prone to incomplete penetration defects. 2) is similar to aluminum, as stainless steel w (Cr)> 12%, chromium preferentially combines with oxygen in the surface layer of the base metal oxide Cr2O3 dense than iron, melting point up to 2265 ℃ Shandong fine pull rod prices, The melting point of chromium is 1857 ℃, there will be similar problems. Mechanical cleaning: the workpiece size is larger, longer production cycle, multi-layer welding or chemical cleaning after contamination, often by mechanical cleaning. With acetone, gasoline and other organic solvents to wipe the surface of the oil, followed directly with a diameter of 0.15 mm ~ 0.2 mm copper wire brush or stainless steel wire brush, brush the exposed metallic luster so far. Generally should not use the wheel or ordinary sandpaper, in order to avoid sand left on the metal surface, into the bath defects such as slag generated during welding. There is also available scraper, rasp and other clean-up surface to be welded.
