-
Perform GMA welding.
WarningDo not weld the panel where it directly contacts the high strength panels underneath. The heat from welding might weaken the strength of the underlying high strength steel structure.WarningFailure to follow all welding safety precautions, including the use of personal protective equipment, could result in serious injury or property damage. Only technicians who have completed Tesla’s approved welding training are authorized to weld structural components on Tesla vehicles.WarningTo maintain vehicle crash integrity, use only approved welding wire and an approved GMA welder to perform GMA welding on Tesla vehicles. Refer to Approved Gas Metal Arc (GMA) Welders and Welding Wire for information on approved GMA welders and welding wire.WarningBefore GMA welding, make sure that the structural adhesive is dry to the touch. If the structural adhesive is not dry to the touch before GMA welding, the strength of the adhesive bond might be compromised.CAUTIONDo not weld on a Tesla vehicle before performing the Vehicle Electrical Isolation Procedure (refer to the vehicle-specific Service Manual for more information on the Vehicle Electrical Isolation Procedure). Welding on a Tesla vehicle with an energized high or low voltage system might damage vehicle components.NoteBefore GMA welding, a test weld using material of the same gauge and type should be performed to make sure that the welding equipment settings produce a satisfactory joint.
