Welding Arc Stability
AC Welding: The stability of AC arc is relatively poor. The direction of the alternating current changes periodically, and the arc will extinguish and re-ignite when th...
Welding electrodes are metal wires with baked on chemical coatings. The rod is used to sustain the welding arc and to provide the filler metal required for the joint to be welded. The coating prote...
The submerged arc welding process is the most ideal choice in the important application fields of pipelines, pressure vessels and tanks, track manufacturing and major construction. It has the simpl...
