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...
The primary function of welding shielding gases is to isolate the weld pool from the atmosphere, stabilize the arc, control penetration depth, and enhance overall weld quality. Conversely, select...
1. What is arc striking? What are the ways to start an arc? What should you pay attention to when striking an arc?
The process of igniting and producing a stable arc is called arc ignition. There...
Many welding problems that show up on the shop floor—poor bead appearance, porosity, cracking—are often traced back to one overlooked factor: how the consumables were stored before they ever rea...
Welding can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the constructio...
During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
