4.7.1Application of Laser Seam Tracking and Arc Tracking in Construction Machinery Welding
Application difference between laser seam tracking and arc tracking
Arc tracking Laser seam tracking
Arc Tracking | Laser Seam Tracking | |
Principle | Feedback from current and voltage Sensors to identify changes in torch position | Based on the principle of line Structured light projection, a laser contour line is formed on the surface of the weld, and the feature points of the weld are found through the contour. |
Cost | Cheap | Higher |
Efficiency | Swing is required during the welding process, and the welding torch needs to be cleaned frequently, etc., and the efficiency is low | Real-time tracking and detection of welding seam position, guiding the welding gun for precise welding, high efficiency |
Applicable Weld Type | Suitable for large welds with significant structure, such as large bevels and fillet welds | Applicable to all common types of welds, including small welds, multi-layer multi-pass welds, etc. |
Construction machinery equipment and characteristics
Definition
Various construction machinery;Common ones are: excavators, shield machines, shovel transport machinery, cranes, compaction machinery (road rollers),
road machinery, piling machinery, etc.
Features
- Long R&D and production cycle, high technology content;
- The workpiece is large in size, mostly medium and thick plates;
- The amount of welding tasks is large, and the manual operation is difficult;
- Welding quality requirements are high and must be tested by flaw detection;
- low degree of automation;
- Various types of welds;
- Most manufacturers currently use the positioner to solve the problem.

Remarks:
If your seam type is complex and has high requirements on production efficiency, it is recommended that you choose laser seam tracking.
