Application of robotic welding in the metal industry

Robotic welding In many areas of industry, especially in the metal industry, it is an increasingly widespread technology. In the production of structural metals, pipelines and tanks, it is particularly important to create heavy-duty and precise weld seams, which robotic welding systems can provide efficiently and reliably.

Why is robotic welding advantageous in metal structure manufacturing?

Superior accuracy and repeatability

Thanks to the programming of robots, each weld seam is made according to the same standards with minimal error. This is especially important for structural elements and pressure vessels, where the quality of seams is critical.

Increased productivity

Robots can work continuously without human fatigue. This allows the production process to be faster and more efficient, reducing production time.

Load-optimised seams

Robotic welding allows the specific behaviour of the material to be taken into account, thus optimising the strength and durability of seams, which is especially important for pipelines and tanks.

Cost effectiveness

Although the introduction of robotic welding technology requires a significant initial investment, it can be more cost-effective in the long run as the number of rejects is reduced and labour requirements can be optimized.

Safe working environment

The heat, light and gases released during welding work can be dangerous for human workers. Robots take on these hazardous tasks, reducing risks to the working environment.

Spheres of application

Robotic welding supports metallurgical production in many applications:

  • Manufacture of structural elements: For example, bridges, building frames or larger machine structures.
  • Pipelines: Manufacture of pipelines for the oil and gas industry, where leakproofness of seams is critical.
  • Tanks: Pressure vessels, liquid containers or heat exchangers where welding quality affects operational safety and efficiency.

Most common robotic welding technologies

MIG/MAG welding (metal gas arc welding)

This is the most common process, which is excellent for welding steel and aluminum structures. The precise control of the robots enables precise seams to be formed.

TIG welding (tungsten electrode arc welding)

It is mainly used for thinner materials and more demanding seams. It is especially important for stainless steel and special alloys.

Spot welding

It is excellent for joining thin sheets of steel, for example in the automotive industry and tank production.

Laser welding

Extremely precise and fast process that uses a high-energy laser beam. Ideal for complex geometries and thin materials.

Advanced technologies in robotic welding

  • Automatic seam tracking: The robot uses sensors to monitor the seam position and correct the weld path.
  • Artificial intelligence and machine learning: Robotic welders are increasingly able to learn from repetitive tasks and improve seam quality.
  • Remote control and monitoring: Operators can monitor the welding process in real time and intervene if necessary.

The introduction of robotic welding in the metal industry not only increases productivity, but also makes it possible to perform precision jobs that were previously difficult to perform.

Concluding thoughts

Robotic welding in the metal industry It has been given an outstanding role, as it not only increases the efficiency of production processes, but also raises quality to a higher level. In various sectors of the industry – be it structural components, pipelines or tanks – robotic welding provides the precision, reliability and strength required to produce safe and durable products.

Robotic systems Due to its continuous operation, repeatability and reduction of labour demand, they can result in significant cost savings in the long run. In addition, since robots are better able to avoid errors than human workers, continuous optimization and improvement of production processes is possible.

Robotic welding is therefore not just a new technological trend, but has become an essential tool in the metal industry, bringing numerous benefits to both manufacturers and end users.

What is edge bending and in which industries is this technology used?

Edge bending is one of the most commonly used metalworking process, in which metal sheets are bent to a specific angle or shape to meet manufacturing specifications. This technology is key to many industries, producing durable, accurate and aesthetically pleasing metal parts. In this article we explain what edge bending is, how it works and which industries benefit from it.

What is edge bending?

Edge bending in which a metal sheet is clamped between the tools of a bending machine (such as an edge bending press) and the material is then bent to a specific angle or shape. The behaviour of the metal during this process depends on three basic factors:

  • The quality of the material: During bending, the metal is subjected to both tensile and compressive forces.
  • The geometry of the tool: The shape and size of the bending tool determines the shape of the finished product.
  • The bending angle and the compressive force: The right angle and pressure guarantee the desired result.

The precision of the process is of paramount importance, as the end result must be not only functional but also aesthetic, especially in industries where visible elements are involved.

How is edge bending done?

Edge bending process in general modern bending machines which ensure precise movement and power distribution. The main parts of the machines are:

  • Upper tool (bending blade) that acts on the material.
  • Lower tool (sticker) that supports the plate.

In the operation of the machine, the metal plate is placed between the two tools and the pressure of the upper tool causes the plate to take the shape of the lower tool. The result is a precision-bent metal part.

Use of edge bending in different industries

The versatility of edge bending makes it a preferred method for many industries. Here are some examples:

 

Construction

In the construction industry, elements made of bent sheet metal are often used, for example:

  • Roof tiles
  • Gutters

Special edge bending machines that automatically bend sheets from several sides. They are mainly used to produce complex box shapes and framed parts.

  • Benefits: High precision. Ability to produce complex bending patterns.
  • Usage: Electronics and furniture industries where complex, multi-sided bending is required.

Robotic edge bending systems

Automation is becoming more and more important in the industry, so robotic edge bending systems are becoming more common. These systems use robotic arms to position the plate while the bending machine does the actual work.

Benefits:

  • High efficiency in high-volume production.
  • It requires minimal human intervention.
  • Suitable for more complex parts.
  • Usage: Automotive industry, large series production.
