adequate visibility are recommended. It is strongly recommended that persons working in the weld area wear
flash safety goggles. Also wear protective clothing. Failure to follow these instructions may result in serious
personal injury.
NOTICE: Hybrid vehicles contain a High Voltage Traction Battery (HVTB). Before welding near the HVTB , the
HVTB must be removed to avoid heat damage. For information, refer to
The correct equipment and settings must be used when welding mild or high-strength steel. Metal Inert Gas (MIG) and
Squeeze-Type Resistance Spot Welding (STRW) are the preferred methods. Surfaces must be clean and free of
foreign materials.
• Correct eye protection must be worn.
• The correct protective clothing should always be worn.
• Adequate ventilation must be provided to avoid accumulation of poisonous gases.
• Refer to the Ford Recommended Steel Repairability Matrix in the Specifications portion of this section for
specific information regarding steel descriptions.
• A test weld should always be carried out on a test sample.
• Use cleaning brushes and abrasive grinding wheels dedicated to the type of materials being welded.
• Follow equipment manufacturer's prescribed procedures and equipment settings for the type of welder being
used. ER70S-3 or ER70S-6 wire are typically used for MIG welding steel.
• On non-hybrid vehicles, disconnect the battery ground cable. Refer to
• Disconnect on-vehicle modules and protect them from possible heat damage and electrical currents when
welding.
• Corrosion protection must be restored whenever bare metal repairs are made. Refer to
Protection Following Repair
• Weld through primer is recommended when welding overlapping surfaces or substrates.
• Components made of high-strength steel should not be heated should not be heated to straighten or repair. If
components are severely bent or kinked, new components should be installed.
• Adequate power supply needs to be used to make sure of correct equipment performance.
• Factory spot welds may be substituted with either STRW or MIG plug welds. Spot/plug welds should equal
factory welds in both location and quantity. Do not place a new spot weld directly over an original weld
location. Plug weld hole should equal 8 mm (0.31 in) diameter.
• Vehicles equipped with optional safety canopy require removal of these components prior to any welding
procedures being carried out in the roof-line or body side areas of the vehicle. Refer to
in this section.
