Re: [MW:32445] Defects in welding

Dear Gujar 

Try increasing the stick out to 25 -30 mm and decrease the volts to 27 and also check the gas flow at the outlet of the torch near the contact tip if its really 15-18.

If the formulation is correct than there could be humid powders in the flux and improper lubrication could be the reason of these gas marks or pores. Also check if the wire is feeding constantly or its sleeping.

Dear Experts,

We are facing defects in the stainless steel welding as per attached images, kindly let me know what could be the reason. 

Please note below information,

Consumable type: SMAW
Grade:E309LT1-1
Base metal: E309L plate
Co2 gas flow: 15-18
V: 28V
Current: 180-200 amps

Same batch of flux cored wire E309LT1-1 has worked just fine on the other jobs with similar applications. 

Thanks in advance. 

Regards,
