Applications of induction soldering across different industries

What is induction soldering and why should it be considered?

Induction soldering is an advanced metal joining technology that uses the principle of induction heating. The process involves generating heat in the soldered components by means of eddy currents induced by an electromagnetic field. The heat produced in this contactless way heats both the joined parts and the solder, which, after melting, fills the gap between the components and forms a durable and precise joint.

Why consider induction soldering?

Precision:
Heat is generated only at the joint area, which helps prevent overheating of surrounding materials.

Energy efficiency:
Energy is used only where soldering takes place, minimizing heat losses and reducing production costs.

Process cleanliness:
The absence of an open flame and physical contact with components reduces the risk of contamination and damage.

Speed and repeatability:
Short heating times and the possibility of process automation make induction soldering well suited for large, repeatable production series.

Versatility:
The technology is used across various industries, such as electronics and automotive.

Key applications of induction soldering:
Induction soldering is particularly effective in processes that require rapid heating and precise heat delivery. For example, in the electronics industry.

Companies that choose to implement induction soldering gain access to a modern, energy-efficient technology that increases production efficiency and reduces costs. It is a forward-looking solution that helps meet the growing demands of the market.

Induction soldering is used in selected industrial sectors where standard soldering techniques may be insufficient due to the thermal mass of components, the need for selective heating, or specific joint geometries. This technology is applied in both soft soldering and brazing processes, always as a solution tailored to a specific application.

Electronics

In the electronics industry, induction soldering is mainly used in special applications that complement conventional processes such as reflow or wave soldering. It is well suited for soldering components with high thermal mass, such as heat sinks, large connectors, terminals, or wire harnesses, where achieving uniform joint heating can be difficult with standard methods.

Induction soldering also enables electronic components to be joined directly to metal housings or shields, where localized heating is required without affecting other parts of the assembly. Thanks to the selective nature of the process, thermal impact on sensitive components can be minimized.

RF connectors and test equipment

In the production of RF connectors and test and measurement cables, induction soldering is used for precise soldering of high-frequency connectors such as SMA and similar coaxial designs. Maintaining stable electrical parameters requires a repeatable process and good control of the heating zone.

Induction technology allows localized heating of the connector without excessive thermal load on the cable or insulation, which is important for preserving the mechanical and electrical properties of the finished assembly.

Wire harness production

Induction soldering is used in wire harness manufacturing, particularly for soldering wires to terminals, connectors, or other components with higher thermal mass. In such cases, conventional methods may require longer heating times or result in uneven solder flow.

The selective heating approach enables stable and repeatable joints, which is essential in the serial production of harnesses used across various industrial sectors.

Photovoltaics

In the photovoltaic industry, induction soldering is used to create electrical connections in PV panels, where joint quality is critical while limiting the thermal impact on neighboring elements. Controlled heating enables durable connections without the risk of damaging cells or encapsulation materials.

This technology is mainly applied at selected stages of the process where point or selective soldering is required.

Cutting tools – saws and drills

In brazing applications, induction soldering is used in the production of cutting tools such as saws and drills, where cemented carbides must be securely joined to steel bodies. This process requires precise delivery of thermal energy to ensure joint quality without overheating the tool.

Induction allows localized heating of the soldering zone, supporting process stability and joint repeatability in serial production.

HVAC industry

In the HVAC sector, induction soldering is used for brazing copper pipes, particularly in systems operating under high pressure and mechanical loads. The technology enables the creation of tight and durable joints in air conditioning, refrigeration, and heating systems.

The localized nature of heating helps limit the thermal impact on surrounding areas, which is especially important when working with complex piping assemblies or components with intricate geometries.

Production processes across different industries

Induction soldering is one of the technologies used in production processes across various industries, particularly where selective heating is required, where good control of process parameters is important, or when working with components that have high thermal mass. It does not replace conventional soldering methods but rather complements them in specific applications.

In serial production, induction soldering is sometimes used at selected stages of the process, for example to perform repeatable point joints or to solder components that are difficult to heat using standard methods. In such cases, the localized nature of heating can help stabilize the process and limit the thermal impact on neighboring components.

In applications with more complex technical requirements, such as the production of specialized components for the energy sector, HVAC, or cutting tools, induction soldering enables heating parameters to be adapted to a specific joint. Control of power, time, and the characteristics of the induction field allows the process to be matched to materials with different thermal and mechanical properties.

In practice, induction soldering can support production processes, among others, by:

Facilitating automation of selected operations: the technology performs well in repeatable, selective, or point-based processes.
Improving joint repeatability in specific applications: stable heating conditions help maintain consistent joint quality, especially for massive components.
Limiting thermal impact on the area surrounding the joint: localized heating can reduce the risk of overheating adjacent components.
Improving workstation organization: the absence of an open flame and the contactless nature of the process can simplify integration with production lines and safety systems.

Induction soldering is not a universal solution for all production processes; however, in properly selected applications it can be a valuable technological tool. The final decision to implement it should always be based on an analysis of the specific process, the types of components being joined, and the required quality and economic criteria.
