With the rapid development of industrial automation technology, robot welding equipment has become one of the core equipment in modern manufacturing. With its high - precision and high - efficiency welding capabilities, it has significantly improved production quality and stability, and is widely used in multiple fields such as automobile manufacturing, aerospace, rail transit, and household appliance manufacturing.
I. Main Classification of Robot Welding Equipment
1. Classification by Welding Process
- Spot Welding Robot: Specialized in connecting thin - sheet metals, it fixes the welding points through pressurization and instantaneous high temperature, and is especially suitable for automobile body welding. For example, a single automobile body usually requires 3000 - 5000 welding points to be completed, and robots can achieve efficient mass production.
- Arc Welding Robot: Using an electric arc as a heat source, it is suitable for welding complex curves of materials such as steel and aluminum alloy, and is commonly found in heavy industry, pipeline manufacturing, and metal structural part processing.
- Laser Welding Robot: It uses a high - energy laser beam for precision welding, with a small heat - affected zone and beautiful welds, and is suitable for high - precision fields such as electronic components and medical devices.
- Resistance Welding Robot: It melts metals by passing electricity through electrodes and is mostly used in household appliance manufacturing and thin - sheet welding.
2. Classification by Mechanical Structure
- Articulated Robot: It has a six - degree - of - freedom mechanical arm, high flexibility, and can complete complex welding tasks at multiple angles. It is the most widely used structural type at present.
- Cantilever Robot: Suitable for welding scenarios with large - area coverage, such as large metal structural parts.
- Vertical Robot: It has a compact volume and is suitable for vertical welding scenarios with limited space.
3D laser cutting technology is widely used in the new energy vehicle (NEV) industry, primarily for high-precision processing of complex metal components. This technology utilizes high-energy laser beams to achieve rapid material cutting and is suitable for various metals, including aluminum alloys, high-strength steel, and copper alloys.
In battery manufacturing, 3D laser cutting is applied to process battery trays, enclosures, and conductive connectors. Battery trays require precise cutting of cooling holes, mounting holes, and edge contours, where laser cutting ensures smooth edges, eliminates burrs, and maintains sealing integrity. Conductive connectors demand extreme cutting accuracy, and laser technology minimizes thermal distortion while preserving electrical conductivity.
For vehicle body production, 3D laser cutting is ideal for processing aluminum-steel hybrid materials. To reduce weight, NEVs often use aluminum alloy or hot-formed steel components such as crash beams and A/B pillars. Unlike traditional stamping, which requires custom molds, laser cutting directly follows 3D models, adapting to complex curvatures and shortening production lead times.
