The welding robots have transformed the manufacturing industry through enhanced accuracy, efficiency, and safety in the welding process. These robotic systems perform various welding tasks, which are highly uniform, which rules out the element of human error, and which improves productivity.
What Are Welding Robots?
The robots used to perform the welding exercise are computerized machines, which are very precise and consistent in performing the exercise. These are equipped with sophisticated sensors and computerized control systems and are utilized to make various kinds of welding, including arc welding, spot welding, and laser welding. Moreover, it has been anticipated that the global market of welding robots will cost approximately 4.5 billion dollars in 2024, with the rate approaching 7.2 billion dollars in 2032, with a compound annual growth rate (CAGR) of 6.1.
Advantages
- Greater Accuracy: Welding robots offer the quality and accuracy of human-reduced error in welding.
- Increased Productivity: They also operate twenty-four hours, thus increasing productivity.
- Safety is improved: The risk of being exposed to dangerous conditions is not experienced by human beings since the work is done by robots.
- Cost Savings: Automation will save the workforce and reduce wastage.
- Flexibility: Re-programming robots will offer them flexibility in other welding activities.
Disadvantages
- High Start-up Cost: The Initial cost of purchasing and installing welding robots can be colossal.
Types of Welding Robots
The type of welding is another category of welding robots. Here are the 4 major types of welding robots:
Arc Welding Robot
The Arc welding robots will be used in such spheres of activity as MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding. They are widely applied to the building of ships and the heavy equipment field, and the construction of the infrastructure as well. The smoothness of six-axis robots in trajectory control and adaptive motion planning allows them to remain on a uniform arc and achieve welding penetration at difficult angles.
Spot Welding Robot
They are applied in the automotive sector primarily, where the Spot welding robots find use in welding metal sheets. Their cycle time is extremely low, and they are very efficient; thus, they are extremely appropriate for mass production. The six-axis welding robots within the spot welding robots subcategory had an equivalent distance of 42 in market share in 2024.
Laser Welding Robot
Laser welding robots are designed to use focused laser beams to bond materials, and this is very precise, so that very little distortion of heat is created. They are also venturing into other sectors such as aerospace and electronics.
Collaborative Welding Robot
The welding robot also possesses cobots that will liaise with the human workers. They best suit small and medium-sized businesses to be utilized as long as they are flexible and can be easily coded. The collaborative robots are also in high demand, and companies such as KUKA and ABB are leading in this sphere.
Applications and Industry Standards
They have both been used in industrial applications and standards. The welding robot identifies with industries, thus facilitating productivity and giving a high level of welds.
Automotive
It will need the welding robot, like chassis building and body-in-white, in the automotive industry. In 2024, the automotive industry had more than forty-five percent of the total amount of all the welding robots in the world.
Heavy Equipment
The welding robots find their application in the manufacturing of heavy equipment because they are engaged in structural welding and assemblies. They are rather stringent and efficient in terms of the production of massive machinery.
Pressure Vessels
The manufacture of the pressure vessels also uses a welding robot to accomplish the welds, which are uniform and of quality, which is important in the safety and performance.
Shipbuilding
Through the welding of robot, hull and bulkhead welding is performed in the shipbuilding process. This type of robot can access closed spaces of ships much more easily, besides cutting down on the level of welding by almost 30 percent.
Aerospace
Welding robots are used in the aerospace industry to perform fuselage and engine parts assembly. The accuracy demanded by such robots is such that it can help achieve high-quality standards in the industry.
