Pores
Pores in the weld metal are caused by some disturbance in the gas shield, but there
are also different reasons.
Wrong setting of gas flow. The flow must be enough; it should be adjusted according
to the welding current. To high amount of gas will cause problems with turbulencein
the gas nozzle.
Draught in the place of welding. Airspeed above 0.5can interfere with the gas
stream from the gun (somewhat depending on the setting of the gas flow).
Defect equipment. Clogged channels or leakage can prevent the gas from flowing.
Control if possible by measuring direct on the opening of the gas nozzle.
