焊接设备保证焊接质量的三大因素

来源:/  发布时间:2021-06-28 浏览次数:

在现今有许多的地方会用到焊接,首先我们要知道哪些东西可以焊接,焊接的厚度多少才比较适合。那么塑料焊接在使用时有哪些需要注意的事项呢?要保证焊接质量的话有哪些重要的因素呢?首先要考虑焊接时的压力和时间等。

Nowadays, welding is used in many places. First of all, we need to know what can be welded and what thickness is suitable for welding. So what should we pay attention to when using plastic welding? What are the important factors to ensure the welding quality? First of all, the pressure and time of welding should be considered.
1、压力。
1. Pressure.
对焊接表面施加适当的压力,焊接材料将由弹性向塑性过渡,还可以促进了分子相互扩散并挤去焊缝中的残余空气,从而增加焊接面密封性能。如果在焊接时未往下压,或者焊条拉伸太大,往往会引起开裂。
Applying proper pressure on the welding surface, the welding material will be transformed from elastic to plastic, which can also promote the mutual diffusion of molecules and squeeze out the residual air in the weld, thus increasing the sealing performance of the welding surface. If the welding is not pressed down, or the electrode is stretched too much, it will often cause cracking.
2、时间
2. Time
要有适当的热熔时间和足够的冷却时间。当热功率一定时,时间不够会出现虚焊,时间过长会造成焊件变形,熔渣溢出,有时还会在非焊接部位出现热斑(变色)。一定保证焊接面吸收足够的热量达到充分熔融的状态,才能保证分子间充分扩散熔合,同时一定保证足够的冷却时间使焊缝达到足够的强度。
There should be proper hot melting time and enough cooling time. When the thermal power is fixed, insufficient time will lead to false welding, too long time will cause deformation of weldment, slag overflow, and sometimes hot spot (discoloration) will appear in the non welding parts. It is necessary to ensure that the welding surface absorbs enough heat to reach the state of full melting, so as to ensure the full diffusion and fusion between molecules, and at the same time, it is necessary to ensure that the cooling time is enough to make the weld achieve sufficient strength.
3、熔融量
3. Melting amount
热熔时间和热功率协调调整才会得到恰当的熔融量,保证足够的分子间融合,消除虚焊的现象。除了焊接设备和操作人员技能水平外,来之于塑料内部或外部的各种因素,对焊接质量有一定的影响,应当引起重视。
Only when the melting time and heat power are adjusted coordinately, the appropriate melting amount can be obtained, enough intermolecular fusion can be ensured, and the phenomenon of false welding can be eliminated. In addition to the skill level of welding equipment and operators, various factors from the inside or outside of plastics have certain influence on the welding quality, which should be paid attention to.
