Buyer’s guide: rebar tying and welding robots

How they work

Rebar robots ride on the mat and tie every crossing; welding robots run in fabrication shops on parts that used to be welded by hand.

What to check before buying

  • Ties or weld metres per hour
  • On site or in a shop
  • Setup time per job
