Tata Steel has unveiled a new high-tech robotic welding line at its Automotive Service Centre in Wednesfield, West Midlands – the largest in the UK. One of only a few in the world, the new robotic welding line trebles the site’s capacity to produce tailor-welded blanks – special sheets of steel made from different thicknesses. These steel parts – often used for car door panels – enable manufacturers to make lighter vehicles with lower emissions, while boosting miles per gallon.
