Dioxyde Silicates slag in Mig Welding
Dioxyde Silicates slag in Mig Welding
(OP)
Hi all,
I've heard that silicates dioxyde slag is a common phenomenon/problem in Mig Welding.
Can anyone tell me more about this ?
Because it gets problematic when you weld on automatic mode and you want to do multiple layers. You don't want to stop the robot and clean the first bead before welding the second one...
So is this related to the process ? (MIG)
Or will any process using a high Si% filler metal will encounter the same problem?
I searched on the forum and haven't found anything helpful.
Thanks in advance for any help!

For solid wire GMAW, the shielding is provided by gas only so there is no real slag that is formed. You can have contaminants in the shielding gas or hydrogen introduced, however, this typically results in porosity or other problems, but not slag.
