Nd@YAG, Gas byproduct Reduction
Nd@YAG, Gas byproduct Reduction
(OP)
I currently use a Nd:YAG for welding ST/ST components. I experience a deposit of a black powder like substance on the components afer welding. This can vary depending on the direction the shield gas (ARGON-Pure)is applied in but is ever present to some degree. Has anyone had similiar experiences and if they have, how can you eradicate this problem, if at all?

Stainless AISI316L welded to same material and also AISI316L welded to AISI304

The amount of deposition is dependant on the joint geometry. With a simple butt weld in two flat components, there should be little or no "soot" deposit.
With a corner weld, where there is a vertical surface close to the weld area, then there will be a heavy deposit of "soot" on the vertical surface.
This is true even when welding in a completely inert atmosphere such as would be encountered in a glove-box.
The upside is that this stuff vipes off easily.
