用来制作针孔蒸镀的钨螺旋Tungsten electrode, it is made of tungsten electrode which has high melting point, corrosion resistance, high density, good thermal and electrical conductivity material. Tungsten electrode is widely used for welding in its properties. Tungsten electrodes are ground or polished and black rod. Their final colors are different and differences can be discerned. In tungsten electrodes, more importantly, the tungsten content also varies depending on their final color. When welding, choosing the right tungsten electrode makes welding easier and it is important to get a high quality weld. Some important factors to consider to make the right choice are the power source (inverter or transformer), the type of welding material (steel, aluminum or stainless steel) and the thickness of the material.
