Why Does the Weld Seam Drift During Handheld Laser Welding?
Weld seam drift can lead to uneven welds and poor fusion. Discover common causes and practical ways to maintain accurate welding paths for more consistent results.
A weld seam that drifts away from the intended joint can cause uneven welds, poor fusion, and rework. If the welding path is difficult to maintain, check these common factors.
1. Unstable Hand Movement
Sudden changes in hand movement can cause the laser to move away from the joint. Keep a steady grip and follow the joint line consistently.
2. Poor Workpiece Alignment
If the parts are not properly aligned or secured, the joint may shift during welding. Check the fit-up and clamp the workpieces before starting.
3. Difficult Joint Visibility
Poor lighting, reflective surfaces, or an unclear joint line can make it harder to follow the welding path. Clean the work area and ensure the joint is clearly visible.
4. Incorrect Welding Position
An inconsistent angle or working distance can make it harder to maintain a stable weld. Keep the Handheld Welding Head in a consistent position suitable for the joint.
Before changing laser parameters, check the joint alignment, workpiece stability, and welding technique. A stable welding path is essential for consistent results.
