Pre-Start Laser Welding Machine Faults & Solutions

1. Equipment Cannot Start (Power)

Solution: Check whether the power cord switch is powered.

2. Lights Cannot Be Lit

Solution: Check the pre-fire board with or without 220V voltage, check the light board; 3A fuse, xenon lamp.

3. The light Has Been Lit, No Laser

Solution: Observe the handheld laser welding machine part of the display out of the light is normal. First of all, check the CNC part of the laser button is closed, if closed, then open the laser button. If the laser button is normal, open the numerical control display interface to see whether the setting for continuous light, if not, then change to continuous light.

2. Cracks

If the cooling speed of the workpiece is too fast, the temperature of the cooling water should be adjusted on the fixture to increase the water temperature.

When the workpiece fit gap is too large or there is burr, the machining precision of the workpiece should be improved.

The workpiece has not been cleaned. In this case, the workpiece needs to be cleaned again.

The flow rate of protective gas is too large, which can be solved by reducing the flow rate of protective gas.

3. Pore On The Weld Surface

Reasons for the generation of porosity:

1) The laser welding molten pool is deep and narrow, and the cooling rate is very fast. The gas generated in the molten pool is too late to overflow, which can easily lead to the formation of porosity.

2) The surface of the weld is not cleaned, or the zinc vapor of the galvanized sheet is volatilized.

Clean the surface of the workpiece and the surface of the weld before welding to improve the volatilization of zinc when heated.

4. Welding Deviation

The weld metal will not solidify in the center of the joint structure.

Reason for deviation: Inaccurate positioning during welding, or inaccurate filling time and wire alignment.

Solution: Adjust the welding position, or filler time and wire position, as well as the position of the lamp, wire and weld.

5. Surface Slag Entrapment, Which Mainly Appears Between Layers

Surface slag entrapment causes:

1) When multi-layer multi-pass welding, the coating between layers is not clean; or the surface of the previous weld is not flat or the surface of the weld does not meet the requirements.

2) Improper welding operation techniques, such as low welding input energy, welding speed is too fast.

Solution: Choose reasonable welding current and welding speed, and the interlayer coating must be cleaned when multi-layer multi-pass welding. Grind and remove the weld with slag on the surface, and make up the weld if necessary.
