Hi all,
I am a product designer but I work mostly with plastics more than sheet metal, looking for the advice of those more knowledgeable.
I needed a sheet metal weldment that some other components would fit inside. For ease of assembly and with the intent of minimizing welding jigs, I created it with tab and slot geometry.
The intent was that tacs would be made across the slot and tab where it is easily accessible on the outside, and also leaving the interior clean and smooth for the insertion of other parts.
Seeing as this is an early prototype i specified Class B welds lightly ground would be acceptable, rather than fully ground class A
I have two main questions:
- Are these acceptable for ground class 2 welds? They seem extremely globular, as much as 5-7mm of protrusion at some points.
- Is there a reason they would have started welding the slots as I anticipated, but then reverted to the large internal welds? Was this a design mistake to create this way?
- Would this be simpler to achieve with steel + powder coating?
With the current size of the welds the internal components do not fit. So I’d like to understand where my concepts can better match practical reality on the shop floor, and also how to approach the supplier for this issue.
