Spot Welding

Spot welding is effective for several materials, including:

• Mild Steel
• Stainless Steel
• Wire Mesh

These materials are commonly used in spot welding due to their ability to form strong bonds through the quick, high-heat application of the spot welding process.

Spot welding differs from MIG and TIG welding in both method and application:

• Assembly: Spot welding is often used to assemble components to precise dimensions before further processing, such as furnace brazing.
• Automation: Spot welding is typically more automated, making it ideal for high-volume tasks. Components are placed in a jig or clamping system, and the machine automatically completes the welds.
• Robotic Integration: Spot welding often uses robotic arms to apply the weld, enhancing consistency and speed, which contrasts with the manual control often seen in MIG and TIG welding.

This makes spot welding particularly useful for fast, consistent results in assembly-line production.

Spot welding is widely used across various industries, especially those that require durable, consistent welds in high volumes, including:

• Automotive
• Aerospace
• Shipping and Marine
• Furnace Brazing

These industries benefit from spot welding’s efficiency, particularly for assembling multiple components rapidly and precisely.

Spot welding does raise some environmental considerations:

• High Energy Consumption: The process uses significant electrical energy to create the necessary heat for welding.
• Fume Emissions: Although relatively minimal, spot welding generates some fumes that require Local Exhaust Ventilation (LEV) systems to minimise exposure.
• Coolant Use: Spot welding machines often require a coolant system, which can involve refrigeration gases. It’s essential to monitor and manage these gases to reduce environmental impact.

With proper equipment and ventilation, these concerns can be managed effectively in a responsible welding operation.

Ceandess maintains high quality standards in spot welding through several practices:

• ISO 9001 Certification: Adherence to ISO 9001 demonstrates our commitment to a rigorous quality management system.
• Destructive Testing: Components are tested to the point of destruction to ensure the welds can withstand stress and meet durability requirements.
• Microscopic Examination: After cutting a weld, it is examined under a microscope to check for integrity and consistency.
• Non-Destructive Testing: We also use non-destructive testing, such as fluid testing, to identify any flaws without damaging the component.

These methods ensure that each weld meets industry standards and provides the durability and reliability expected in high-quality welding.
