Product Description

When to Use Automatic Laser Welding?

A 2000W automatic fiber laser welding machine is built for production lines that need consistent, repeatable seam welds at high volume. Unlike a handheld laser welder that relies on operator skill, an automated system moves the laser head along a programmed path at constant speed and power. This produces uniform weld penetration and bead appearance across thousands of identical parts, which is why it is the standard choice for tube mills, tank manufacturers, and enclosure production lines.

The machine integrates a fiber laser source, a CNC motion system, a wire feeder (optional), and a safety enclosure. The operator loads the part, starts the cycle, and the machine completes the weld without manual intervention. Cycle time per part is consistent and predictable.

What Products Use Automatic Laser Welding?
  1. Stainless steel tube and pipe longitudinal seam welding.
  2. Water tank and pressure vessel circumferential welding.
  3. Electrical enclosure corner and flange welding.
  4. Kitchen sink and stainless steel product welding.
  5. Automotive exhaust component welding.

Who Buys an Automatic Laser Welding Station?

This machine is for:

  1. Tube and pipe manufacturers running continuous seam welding.
  2. Pressure vessel and tank builders needing circumferential welds.
  3. Enclosure and cabinet manufacturers welding corners.
  4. Stainless steel product factories (sinks, appliances, furniture).
  5. Automotive parts suppliers with high-volume welding cells.
Handheld vs Automatic: When to Automate

A handheld laser welder handles one-off parts, short runs, and large assemblies that cannot be fixtured. An automatic station is for production volumes where the weld must be identical every cycle, and where operator fatigue and inconsistency would cause rejects. If you weld the same part 100 times or more per day, automation pays back quickly.

FAQ:

Q: Can it weld around corners and complex paths?
A: Yes. The 4-axis CNC system interpolates X, Y, Z, and rotary motion along programmed paths. Parts with 3D weld paths require a 6-axis robot integration instead.

Q: What is the weld quality compared to TIG?
A: Laser welding produces a narrower heat-affected zone, less distortion, and higher speed than TIG. The weld bead is narrower and requires less post-weld grinding.

Q: Does it need shielding gas?
A: Yes. Argon shielding gas protects the weld pool from oxidation. Gas flow rate is typically 15-20 L/min during welding.

Q: Can it weld aluminum?
A: Yes. Aluminum requires a higher power density and slower speed. The 2000W machine welds 1-3mm aluminum with appropriate focus and gas settings.

Q: How long does it take to change over between parts?
A: Program changeover between similar parts takes 10-20 minutes. New part programs are created offline using the CNC software and tested on the sample fixture.
