Laser welding machine as an advanced welding method, in all walks of life have applications. In the process of laser welding machine, there will always be some big and small failures. The following is a summary of the common failures of laser welding machines and solutions.
Failure of a laser welding machine screen are in a black screen state
Laser welding machine screen problems, find the cause in time, repair or replace the screen.
Failure two, laser welding machine welding depth is not enough
1) laser energy is not enough, can improve the pulse width, increase the current to solve.
2) focusing mirror out of focus is not the right amount, should be adjusted to focus the amount of out of focus near the focal point position (but can not have spatter generated).
Failure three, laser welding machine in the use of the host in the process of shaking state
Laser welding machine under the foot of the base is not fixed, or only fixed part of the solution: the laser welding machine base can be fixed!
Failure four, laser welding machine welding workpiece when cracks appear
1) the flow of protective gas is too large, can reduce the flow of protective gas to solve.
2) The cooling speed of the workpiece is too fast, you should adjust the temperature of the cooling water on the fixture to increase the water temperature.
3)The workpiece is not cleaned, in this case you need to re-clean the workpiece.
4)The fit gap between the workpiece is too large or burr, should improve the machining accuracy of the workpiece.
Failure five, laser welding machine welding fire weakened
1) the main optical path laser offset, solution: adjust the main optical path full reverse and half reverse diaphragm, using like paper to check and round the spot.
2) cooling water contamination or long-term cooling water has not been replaced, solution: replace the cooling water and clean the UV filter glass tube and xenon lamp.
3) focusing lens or laser resonant cavity diaphragm damage or contamination, solution: replace or clean the focusing lens and resonant cavity reflection diaphragm.
4) The laser is not from the focusing head below the copper air nozzle output, solution: adjust the 45 degree reflective diaphragm, so that the laser output from the air nozzle.
5) the light gate is not fully pop open, solution: check and add lubricant on the light gate connectors, so that the connectors can be mechanically smooth.
6) protective gas is open too large, solution: adjust the gas flow of protective gas.
Failure six, laser welding machine welding seam is very black
1) the protective gas flow direction is wrong, solution: make the protective gas flow direction and the direction of movement of the workpiece is opposite.
2) nitrogen is not open, solution: open the nitrogen.
In addition to the above six common failures of laser welding machine, there are many other failures, when the laser welding machine operator encountered can not deal with the failure, should contact the manufacturer in a timely manner to solve the problem. Chuyuan laser welding machine 24h response to after-sales service, 3d problem solving, is the peer after-sales service. Select laser welding machine, recognize Xinrui laser.
