Spot Welding

Spot Welding Service

Spot welding services offer a highly efficient and cost-effective solution for joining metal components. We use our specialised equipment and years of expertise to provide this service.

Spot welding, also known as resistance spot welding, is a widely used technique that combines metal sheets by applying heat generated by electric current. This process is widespread in automotive manufacturing, electronics, and construction industries.

How Spot Welding Works

Electrode Application: The process begins with two copper alloy electrodes placed on the surfaces of the metal sheets to be joined.
Pressure and Current: The electrodes apply pressure to hold the sheets together while a high electric current is passed through the electrodes. This current encounters resistance at the contact points between the sheets, generating heat.
Welding: The heat can melt the metal at the contact points, forming a molten pool. Once the current is turned off, the molten metal cools and solidifies, creating a solid bond known as a “weld nugget.”
Cooling: After the current is removed, the electrodes remain in place for a brief period to allow the weld to cool and solidify properly.

Key Features of Soldering

Speed & Efficiency: Spot welding is a fast process, typically taking only a fraction of a second to complete a weld. This makes it ideal for high-volume production environments.
Minimal Heat Affected Zone: Since the weld occurs in a very localised area, the surrounding material experiences minimal heat, reducing the risk of warping or damage to the metal sheets.

Benefits of Spot Welding Services

Rapid Process: Spot welding is one of the fastest welding methods, with weld times typically ranging from 0.01 to 0.63 seconds. This rapid cycle time allows for high production rates, making it ideal for assembly line applications, particularly in the automotive industry.
Cost-Effectiveness: Lower Material Costs: Spot welding does not require filler materials or fluxes, which reduces overall material costs. Additionally, the process consumes less energy than other welding methods, contributing to lower operational costs.
High Production Rate Spot welding’s efficiency means that more parts can be produced in less time, further enhancing its cost-effectiveness for high-volume manufacturing.
Minimal Heat Affected Zone Reduced Risk of Warping: The localised heating in spot welding minimises the heat-affected zone, which helps prevent warping or distortion of the surrounding materials. This is particularly beneficial when working with thin metal sheets, as it reduces the likelihood of burning through the material.
Versatility: Wide Range of Applications: Spot welding can be applied to various metals, including mild steel and stainless steel.
