目前焊接铝件的方法有高频焊接、气焊和钎焊,但这些方法都需要具备一定的设备和物质条件,而且对一些结构复杂、薄壁的器件,这些方法是不适宜的。在生产实践中,我们摸索到一种焊补锻铸铝器件的简易方法:将器件上有砂眼、裂缝的地方打磨干净,露出光泽金属,然后用烙铁(150W 电烙铁或火烙铁)蘸取焊料,直接焊补便可(重量在400克以下的铝器件,无需预热)。 The current methods of welding aluminum parts are high frequency welding, gas welding and brazing. However, these methods require certain equipment and material conditions, and these methods are not suitable for some complicated thin-walled structures. In production practice, we explored a simple method of welding forged cast aluminum parts: the device with a trachoma, cracked place clean, revealing shiny metal, and then use a soldering iron (150W electric soldering iron or soldering iron) dipped in solder , Direct welding can be (weight less than 400 grams of aluminum devices, without preheating).
