The materials of welding wheels include chromium zirconium copper,
alumina copper, beryllium copper, beryllium cobalt copper, tungsten
copper, rare earth copper alloy, etc. Commonly used materials are
chromium zirconium copper and beryllium copper. We mainly select
materials based on the usage conditions, welding materials and
required welding life. The welding wheel can weld galvanized
sheets, low carbon steel, low alloy steel, coated steel, stainless
steel, aluminum alloy, etc.
The welding wheel refers to the electrode wheel of the seam welder.
The electrodes of the seam welder are two wheel-shaped electrodes,
the upper and lower ones, and the discharge is continuous or
interval discharge. The welding wheel is suitable for continuous
welding operations at the joints of thin metal sheets, and is
widely used in the welding of heat exchangers, radiators,
automobile fuel tanks, iron cans, etc. During welding, the upper
and lower wheel-shaped electrodes clamp the workpiece to be welded,
and the welding wheels act as electrodes, respectively releasing
positive and negative currents through the workpiece to be welded,
so that the workpieces are contacted to generate heat, and the
workpieces are fused.
The electrode wheel made of copper alloy is primarily used in seam
welding machines for joining sheet metal components. Seam welding
is a process commonly used in industries such as automotive,
aerospace, and manufacturing, where a continuous and leak-proof
weld is required along the length of a seam.
The electrode wheel, along with its round electrode disc, serves
several important functions in the seam welding process:
Electrical Conductivity: Copper is an excellent conductor of
electricity, making it an ideal material for the electrode wheel.
When electrical current passes through the wheel, it transfers the
energy to the workpiece, generating heat at the interface and
facilitating the welding process.
Pressure Application: The rotating electrode wheel applies pressure
to the workpiece, ensuring proper contact and promoting effective
heat transfer. The pressure helps to create a tight joint between
the metal surfaces, resulting in a strong and durable weld.
Heat Dissipation: Copper has high thermal conductivity, meaning it
can efficiently dissipate heat generated during the welding
process. This helps prevent overheating and distortion of the
workpiece, ensuring consistent and controlled welds.
Wear Resistance: Copper alloys used in electrode wheels are often
chosen for their good wear resistance properties. The rotating
motion of the wheel and the friction between the electrode disc and
the workpiece can cause wear over time. Copper alloys are selected
to withstand these conditions and provide a longer service life for
the electrode wheel.
Overall, the electrode wheel made of copper alloy plays a crucial
role in seam welding by providing electrical conductivity, applying
pressure, dissipating heat, and ensuring wear resistance. These
properties contribute to the successful and efficient creation of
continuous, high-quality welds in sheet metal applications.
