The common problems identified for a good quality weld are given in the below table
Most Common Welding Quality Problems
Possible causes and solutions
Long and unstable arc
* Welding voltage is of high value
according to wire diameter and wire
feed speed
Powerless arc
* Welding voltage is of low value
according to the wire diameter and wire
feed speed
Droplets are splashing
* The voltage is too high
* The gas nozzle is not cleaned properly
* Wire speed is set incorrectly
Insufficient welding filling
* Welding speed is higher than it should
be
* Wire feed speed is lower than welding
speed
* Wire diameter is not suitable for the
job
Porous welding
* The gas level is too low or too high
* Splashed droplets accumulate in the
gas nozzle and cause insufficient gas
flow
* The air flow in the welding area
neutralizes the shielding gas
* The material to be welded may be
moist, oily, rusty
Bad welding filling
* Irregular use or incorrect contact part
is used
* Low welding voltage selected
* Irregular welding speed used
Uneven welding
* Wire speed is very high compared to
the voltage value
* Welding speed is very low
Penetration is insufficient
* Wire feed speed is very low compared
to voltage
The wire feeder and welding power source is manufactured in accordance with TS-EN
60974-1. The service lifetime is 10 (ten) years.
