The product is finished accurately in
accordance with the design
dimensions.
The product offers the required
functionality and strength (or safety).
The appearance of the weld satisfies
the required level.
No cracks or holes found in the bead.
The finished product satisfies the
design dimensions and has almost no
distortion.
The welding meets the required
strength.
The bead has uniform waves, width
and height.
Full penetration welds that fuse and
join the entire interface between the
base material or a weld joint including
partial penetration welds should be
used appropriately to ensure the
necessary rigidity.
