How Does Arc Welding Machine Works
The process of welding in which heat is produced by creating an electric arc to join metal workpieces is known as electric arc welding. Electric arc welding is a type of welding that uses a welding power supply to create an electric arc between a metal stick, called electrode, and the workpiece to melt the metals at the point of contact. Electric arc welding can use either DC supply or AC supply and a consumable or non-consumable electrode.
The process of electric arc welding is based on the principle that when an electric current passes through an air gap between two electric conductors, it generates an electric arc, producing intense and concentrated heat. The temperature of the arc between the two conductors is approximately 3500°C to 4000°C. This high temperature creates intense heat at the welding point, melting a small portion of metal in the workpiece.
The electric arc keeps the molten metal pool agitated, thoroughly mixing the base metal with the melted electrode metal. Afterward, the metal pool cools under a protective slag cover left by the electrode. As it cools, a strong weld joint forms between the two metal pieces.
The figure illustrates a simplified circuit of electric arc welding.
In electric arc welding, you can obtain either AC or DC current from a welding power supply. One terminal is connected to the electrode mounted on an electrode holder, held by the welder. The other terminal is connected to the workpiece, and the circuit is completed through the air gap between the electrode and the workpiece.
The length of the air gap (the distance between the electrode tip and the workpiece's surface) is typically 3 mm to 6 mm. Welding is achieved by creating an electric arc between the electrode and the workpiece. The arc's temperature is exceedingly high (around 3500°C to 4000°C), causing the metal in contact with the arc to melt and enabling the weld to form. The welder then gradually moves the electrode in the desired direction to complete the weld.

Exploring Different Types of Electric Arc Welding Techniques
Electric arc welding is a versatile and widely-used method for joining metals together. This technique involves creating an electric arc between an electrode and the workpiece, generating intense heat that melts the metals and forms a strong weld. There are several distinct types of arc welding machines, each with its own unique characteristics and applications. Let's delve into the details of these welding methods:
1. DC Metallic Arc Welding:
In this type of welding, direct current (DC) is used to power the arc. The process employs either a positively-charged electrode (anode) with negatively-charged workpiece (cathode) or vice versa. DC metallic arc welding is known for its stable arc, uniform welds, and the ability to work with various metals and alloys. It's commonly used in fabrication, construction, and manufacturing industries.
2. AC Metallic Arc Welding:
Alternating current (AC) metallic arc welding involves the use of an electrode that alternates between positive and negative polarity. This method is effective for welding metals like aluminum, which require high heat input due to their high thermal conductivity. AC welding is suitable for producing strong joints, especially when dealing with thicker materials.
3. Carbon Arc Welding:
Carbon arc welding employs a carbon electrode to generate an electric arc. This technique is less common today, having been largely replaced by more advanced methods. It's primarily used for welding non-ferrous metals and is often used for repair work, brazing, and soldering.
4. Atomic Hydrogen Arc Welding:
Atomic hydrogen arc welding is an advanced technique that utilizes atomic hydrogen as a shielding gas. Hydrogen gas is dissociated into atomic hydrogen by passing it through an electric arc, creating an environment that facilitates a high-temperature, low-energy welding process. This method is known for its ability to produce extremely high-quality welds with minimal distortion and is often used for specialized applications like aerospace and nuclear industries.
5. Shielded Arc Welding:
Shielded arc welding, also known as covered electrode welding or manual metal arc welding (MMAW), involves a coated electrode that provides both filler metal and shielding gases when it's consumed during welding. The coating creates a protective shield around the weld, preventing contamination and ensuring the weld's integrity. Shielded arc welding is versatile, suitable for various metals and thicknesses, and is often used in construction, maintenance, and repair.
Each type of electric arc welding has its advantages, limitations, and specific applications. The choice of welding method depends on factors such as the type of materials being joined, the required weld strength, the environment, and the expertise of the welder. As technology advances, new variations and techniques continue to emerge, further expanding the capabilities of electric arc welding and its contributions to various industries.
