Severe outgassing when welding die cast aluminum parts

Q. We have a die cast aluminum bracket we are welding to an extruded aluminum part. We are experiencing server outgassing from the die cast part making them unusable. The aluminum is ADC12, shot in Asia. I sent a photo.

So what can be done to minimize this?

Is this the correct material for welding?

Thank you.
