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.
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.
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. Melting amount
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.
