+  A generic multi-layer GMAW weldment.
+description: |
+  This schema describes a welding application consisting of multiple passes.

-        The workpiece to be welded defined by the base metal and the geometric description of the weld seam.
-      type: object
+  The individual weldments are hierarchically grouped into beads, layers and seams. This is reflected by a nested array
+  with the name `weld_seam` and a nesting depth of 4 (seam, layer, bead, weldment).

-        $ref: "#/definitions/weld_seam"
+  Each weldment may contain the following data:
+
+  - process
+  - TCP
+  - welding_current
+  - welding_voltage
+
+  The `process` entry contains all relevant data that describes the welding process. A comprehensive list of all
+  optional and required fields can be [found here](https://weldx.readthedocs.io/projects/weldx-standard/en/latest/generated/schemas/process/terms-0.1.0.html#base_process).
+  `TCP` describes the trajectory of the torch during the weldment process. The TCP data of all weldments must be
+  defined in relation to the workpiece coordinate system.
+  The welding_current and welding_voltage entries refer to signals containing the final measurement data of corresponding dimensions [current] and [voltage].
+
+  > Note that this schema is currently work in progress and some optional data might become required in the future.
