Electrode arc welding, the end of the Welding Electrode Suppliers and the workpiece arc burning between the heat generated by the drug electrode and the workpiece skin and core melt welding, welding deepening rapidly to form the core end of the small metal droplets, through the transition to the arc column partial melting of the workpiece surface, blending together to form pool. Drug skin melting process the gas and slag, not only the air around the pool and arc cut off, and the core and the molten solder, the base material a series of metallurgical reactions, to ensure the formation of weld performance. With the appropriate arc length and arc speed at work constantly move forward, gradually cooling and crystallization of liquid metal bath to form a weld.
Welding arc has the following advantages:

1) The equipment used is relatively simple, relatively cheap and lightweight. Electrode (silver electrode) arc welding using AC and DC welding machines are relatively simple, the welding operation does not require complex auxiliary equipment, just with simple tools. Therefore, the purchase of equipment investment, and easy maintenance, which is one of the reasons it is widely used.

2) does not require auxiliary gas protection. Not only can provide filler metal electrode and the welding process and weld pool can produce a protective outer shielding gas to prevent oxidation, and has strong wind resistance.

3) is flexible and adaptable. Arc welding electrode for single or small quantities of products, short and irregular, anywhere space is not easy to achieve, and other mechanized welding seam. The place where the Welding Cables can be achieved can be welded.

4) Wide range of applications, suitable for most industrial metals and alloys used in welding. Appropriate choice of electrode arc welding electrode can not only welded carbon steel, low alloy steel, high alloy steel welding but also, and non-ferrous metals, the same can not only weld metal and welding dissimilar metals can also be used for cast iron welding and surfacing materials such as metal
