Structural Sectioning Procedures: Volkswagen

Structural Sectioning Procedures: Volkswagen

Ask I-CAR receives many technical inquiries referring to sectioning. The collision repair industry wants to know where can you section, does the OEM have a sectioning procedure, and where can I find the sectioning procedure? Most OEMs allow sectioning to outer body panels and the front and rear rails. Sectioning reinforcements is not as common, as most reinforcements are replaced at factory seams.

Parts are made from various materials including HSS, UHSS, aluminum, and carbon fiber. These parts also have complex designs to collapse or transfer collision forces in a specific manner. Introducing a sectioning joint to many of these parts will alter how the part reacts to those collision forces. For this reason, sectioning a part is only allowed if supported by vehicle maker repair information. Let’s see what Volkswagen says about structural sectioning.

Vehicle-specific Volkswagen repair manuals offer procedures for sectioning of various parts. However, it is crucial to pay attention to the various Notes and Warnings through the entire procedure. For example, in the front longitudinal member (front lower rail) sectioning procedure on the 2016 Beetle, one of the notes pertaining to a laser welded seam states, “50 mm before and behind laser weld seam must not be separated nor welded.”

The vehicle-specific body repair manual is used to determine the required type of welding and sectioning joint for the repair being performed. Failure to follow OEM procedures will sacrifice the safety and quality of the repair.

Volkswagen also has a General Information Body Repair, Body Collison Repair Manual. This manual provides additional information from Safety Instructions to Body Repair Tools to Basic Instructions to Materials for Body Repairs and General Body Repairs. This manual will pull up when searching for vehicle-specific body repair manuals.

Volkswagen has two position statements pertaining to structural sectioning that you should be aware of.

  • Vehicle Body Sectioning which states, “Full body sectioning (sometimes referred to as “clipping”) is a method of repairing vehicles that have been involved in severe rear collisions…Full body sectioning is not an acceptable method of repair on any Volkswagen vehicle.”
  • Unibody Alignment and Repair which states, “Collision repairs to correct structural damage and body panel replacement should only be conducted on VWoA-approved straightening and measuring equipment. Any and all welded structural panels, parts, pieces and components must only be replaced while properly mounted to VWoA approved straightening and measuring equipment.”
