Robotic welding is consistent from morning to night and therefore so will the quality of construction of a wire container.  Can you imagine a welder spending 6-8 hours a day welding something?  Would you not agree that in the first or second hour the welder is fresh and energetic and focused but after a few hours his eyes start tiring, his muscles ache, and his back starts hurting?  You get the picture. The quality of the welds will not be as good as the welds done during the beginning of the day.  As a result the quality of construction of a basket will not be consistent.
