Default 【清大圣科电焊条反骗子】钎焊可用于多种金属的焊接

钎焊的能源可以是化学反应热,也可以是间接热能。××清大圣科×清大 圣科电焊条×清大圣科电焊条设备×清大金桥×清大金桥电焊条设备&t imes;清大圣科气化炉×www.qhsk.cn×清大圣科科技有限公司&ti mes;×
钎焊可以用于焊接碳钢、不锈钢、高温合金、铝、铜等金属材料,还可以连接异种金属、金属与非金属。&tim es;×清大圣科×清大圣科电焊条×清大圣科电焊条设备&times ;清大金桥×清大金桥电焊条设备×清大圣科气化炉×www.qhsk .cn×清大圣科科技有限公司××
它是利用熔点比被焊材料的熔点低的金属作钎料,经过加热 使钎料熔化,靠毛细管作用将钎料及入到接头接触面的间隙内,润湿被焊金属表面,使液相与固相之 间互扩散而 形成钎焊接头。××清大圣科×清大圣科电焊条×清大圣科 电焊条设备×清大金桥×清大金桥电焊条设备×清大圣科气化炉&tim es;www.qhsk.cn×清大圣科科技有限公司××
适于焊接受载不大或常温下工作的接头,对于精密的、微型的以及复杂的多钎缝的焊件尤其适用。× ×清大圣科×清大圣科电焊条×清大圣科电焊条设备×清大 金桥×清大金桥电焊条设备×清大圣科气化炉×www.qhsk.cn ×清大圣科科技有限公司××
钎焊时由于加热温度比较低,故对工件材料的性能影响较小,焊件的应力变形也较小。×&time s;清大圣科×清大圣科电焊条×清大圣科电焊条设备×清大金桥&ti mes;清大金桥电焊条设备×清大圣科气化炉×www.qhsk.cn&time s;清大圣科科技有限公司××
因此,钎焊是一种固相兼液相的焊接方法。××清大圣科×清大圣科电焊 条×清大圣科电焊条设备×清大金桥×清大金桥电焊条设备&times ;清大圣科气化炉×www.qhsk.cn×清大圣科科技有限公司× ×
但钎焊接头的强度一般比 较低,耐热能力较差。××清大圣科×清大圣科电焊条×清 大圣科电焊条设备×清大金桥×清大金桥电焊条设备×清大圣科气化炉& times;www.qhsk.cn×清大圣科科技有限公司××
