Laser weld defects and reasons countermeasures: 1, the welding spatter, laser welding, after the completion of the material or surface appear more metal particles, attached to the material or surface.
Reason: the material or surface cleaning, there is oily be soiled or pollutants, also may be caused by the volatilization of the galvanized layer.
Countermeasures: laser cleaning before welding material or artifacts.
2, weld accumulation: filling welding weld filler material obviously too much, when the weld is too high.
Reason: welding wire feeding speed too fast or too slow.
Countermeasures: increases welding speed or decreasing wire feed speed, or reduce the laser power.
3, partial: welding solidification structure of weld metal is not joint center.
Reason: when welding the positioning, or wire filling welding time and alignment.
Countermeasures: adjust the welding position, or adjust the position of the wire filling welding time and as well as light, silk and the location of the weld.
4, weld sag: weld metal surface, the phenomenon of the recess.
Reason: when soldering, improper welding spot center location, facula center near the center of the lower plate and weld position, causing part of the parent metal melting.
Countermeasures: to adjust light, silk matching.
5, weld interrupt or uneven thickness, weld brazing, not formed weld wire and interrupt or uneven thickness.
Reason: the wire is not stable, or the light of discontinuity, etc.
The stability of countermeasures: adjust the equipment.
6, stomatal: weld surface blowhole.
Reason: the weld surface is not clean, or galvanized sheet zinc vapor caused by volatilization.
Countermeasures: clean the weld surface, improve the volatilization of zinc when heated.
7, flash: when large changes have taken place in the weld track, easy to appear in the corner flash or unequal phenomenon.
Reason: weld track change is big, teaching caused by uneven.
Countermeasures: under the optimal parameters of the welding, and adjust teaching to coherent excessive corner.
