Brand special sale 280A gasoline power generation welding machine electrode arc welding, also known as manual electric fox welding, is a manual operation by welders. It uses the arc generated between the electrode and the workpiece to melt the workpiece and the electrode before welding. The welding process of electrode arc welding first ignites the arc, causing the workpiece and the welding core to melt simultaneously, forming a molten pool; Then the welding rod and coating undergo metallurgical reactions with the liquid metal, forming a dual protection of slag and gas on the molten pool; When the arc moves forward, the molten metal cools and solidifies, forming a continuous weld seam, and the slag forms a slag shell covering the surface.
