This article will introduce the definition, features, and applications of the DXTECH 6-axis laser welding robot.
 

What is the DXTECH 6-Axis Laser Welding Robot?

 
The 6-axis laser welding robot is a device that utilizes laser welding technology to achieve high-precision and high-efficiency welding operations through robotic arms. This robot can intelligently weld without human intervention, with high positioning accuracy and a large processing range, making it suitable for various materials and shapes. The advantages of laser welding robots include stable welding quality, improved product qualification rate, reduced labor intensity for workers, increased production efficiency, suitability for large-area spatial welding, intelligent operation, flexibility, reliability, the ability to connect six axes, and perform welding in any space, not limited to flat welding.
 
Its intelligent control system functions similarly to a skilled welder, allowing it to be flexibly applied to weldments of different specifications. The robot laser welding machine uses laser as the heat source for welding. The robot laser welding machine can irradiate high-energy-density laser beams onto two material parts, locally heating and melting them, and then cooling and solidifying them to form a whole.
 
 
DXTECH robot laser welding machine adopts the FANUC M20ib series robot, combining lightweight hollow upper arms and wrists with advanced servo technology. In addition, the laser welding head uses the WSX oscillating laser head, which has multiple swinging modes, allowing irregular welding and larger gaps in workpieces.

Stable welding quality, improved product qualification rate
 
Before welding different workpieces, the robot automatically identifies the weld seam and deposits welding material to fill the seam. The weld seam is aesthetically pleasing and robust, resulting in high consistency of welded parts and improved product qualification rate.
 
Reduced labor intensity for workers
 
Welding robots with auxiliary devices can automatically flip thick plate weldments and perform repetitive production, freeing workers from heavy welding tasks.
 
Increased production efficiency
 
Traditional welding is affected by welding environments and human factors, resulting in slower work processes and hindering the rational arrangement of production for companies. The DXTECH 3D robot laser welding machine has a high degree of automation, allowing for continuous operation and long-duration welding tasks, thus helping companies improve production efficiency.
 
Cost reduction
 
In traditional welding, welding defects such as under-welding, misalignment, and over-welding can occur, increasing material costs for companies. Laser welding robot can deposit welding material according to the weld seam, making full use of the welding material while ensuring precise welding. One operator can simultaneously operate two to three welding robots, reducing labor costs for companies.
 

Basic Performance Requirements of Laser Welding Robots

 

Welding Speed: The welding speed needs to match the welding quality. Excessive welding speed can affect the welding quality and may result in welding deviations, insufficient welds, and welding defects. If the welding speed is too slow, it can impact the production process. Welding speed is an important indicator that determines welding efficiency.
 
Rated Load of the Wrist: This refers to the maximum load that the robotic laser welding machine can bear at its end. The rated load of the wrist determines its arm reach and the specifications of the welding workpieces. It includes the load of the welding gun, cables, visual sensors, wire feeding tubes, etc.
 
Number of Axes: It refers to the joints of the robotic laser welding machine. The flexibility of the robotic laser welding machine varies with the number of axes. A higher number of axes provides better flexibility, accommodates a wider range of workpiece sizes, and enables more versatile welding applications.
 
Arm Reach: It reflects the welding radius of the 3D robot laser welding machine. A longer arm reach allows for a larger welding radius and accommodates larger workpiece sizes. Users can select the arm reach of the robot laser welding machine based on their welding space, workpiece specifications, and welding requirements.
 
Machine Weight: The weight of the robot laser welding machine varies depending on its specifications, arm reach, and welding range.
 
Repeatability: It reflects the welding accuracy maintained by the robot laser welding machine during repetitive actions. A high-quality robot laser welding machine should maintain welding accuracy without deviations.
 
The movement speed of the robotic laser welding machine is an important indicator, requiring fast completion of small-spacing multi-point positioning (for example, positioning after moving a distance of 30-50mm every 0.3-0.4 seconds). To ensure welding quality, high positioning accuracy is required (generally within 0-25mm).

What fields can the DXTECH 6-axis laser welding robot be used in?


 
Engineering Machinery Manufacturing
 
With the increasing welding tasks in the machinery manufacturing industry, welding is already a hazardous occupation with poor working conditions and high thermal radiation. The machinery manufacturing industry also involves many large-scale equipment, which adds to the difficulty of welding. Robotic laser welding equipment is an automated mechanical device for welding, which reduces the labor intensity of workers and helps improve the automation level in the machinery manufacturing field.
 
Automotive Manufacturing
 
In recent years, to meet the demands of the public, the automotive industry has shown diversified development, and traditional welding methods no longer meet the high welding requirements for automobiles and automotive components manufacturing. DXTECH 3D laser welding robot can achieve precise welding of weld seams, ensuring proper filling of welding materials and creating aesthetically pleasing and robust welds. Automation welding equipment assembly lines have been established in many modern automotive production workshops.
 
Electronics Equipment
 
The electronics equipment field has high requirements for welding quality. With the increasing demand for electronic devices in society, the development of electronic equipment is progressing rapidly but also faces severe challenges. The 6 axis laser welding robot can ensure stable welding quality while maintaining production efficiency, achieving precise welding of electronic devices, and increasing efficiency three to four times compared to manual methods.
 
Shipbuilding
 
In ship structures, there are nearly a thousand welding components and tens of thousands of parts involved. Most of the critical load-bearing components of a ship use welded parts, and the pressure on the ship's hull during operation is significant, requiring strict welding standards. Robotic laser welding machine, through flexible setting of welding parameters using automatic seam tracking technology, can accurately weld different parts of the ship.
