Process
CB welding is a versatile welding process that can be used to join a wide variety of metals, including steel, aluminum, and stainless steel. It is often used in the construction and repair of bridges, buildings, and other metal structures.
-
Facet 1: The electric arc
The electric arc is the heart of the CB welding process. It is created when an electric current passes between the electrode and the workpiece. The arc melts the metal at the joint, creating a weld pool that solidifies to form a strong bond. -
Facet 2: The consumable electrode
The consumable electrode is another key component of the CB welding process. As the electrode melts, it provides filler material for the weld pool. This helps to create a strong, durable weld. -
Facet 3: The shielding gas
Shielding gas is used to protect the weld pool from the atmosphere. This helps to prevent the formation of oxides and other impurities, which can weaken the weld. -
Facet 4: The welding machine
The welding machine is used to supply the electric current and shielding gas. It also controls the welding parameters, such as the voltage, amperage, and travel speed.
These are just a few of the key components of the CB welding process. By understanding these components and how they work together, you can improve your welding skills and produce high-quality welds.
Equipment
The equipment used in CB welding plays a vital role in the quality and efficiency of the welding process.
