Honda/Acura Sectioning Clarification
In 2014, our contacts at Honda provided us with clarification on their Body Repair News on Body Repair Manual Welding & Sectioning Guideline Revisions. (see figure 1) This information is included in the I-CAR Collision Repair for Honda and Acura Vehicles (HON01e) course. Here are the highlights of their sectioning clarification.
Do not section reinforcements unless a specific procedure is provided in the body repair manual. Replace body structural parts such as stiffeners, reinforcements, and other multi-layered steel parts as assemblies that match the replacement parts configuration, or body repair manual repair procedure.
Steel parts with a tensile strength of 780 MPa or less may be sectioned provided all of the following conditions are observed:
- sectioning must be done in a single-layer area of the part. To determine if a part has a single-layer area that can be sectioned, refer to the body construction pages in the “General Information” section of the appropriate body repair manual to determine the steel grade(s) and part configurations of the parts being replaced. (see figure 2)
- if a part has multi-layer internal steel reinforcements and/or stiffeners, the area of the part where the reinforcements and/or stiffeners are located must not be cut. Inspect the original and replacement parts to determining if there are internal reinforcements and / or stiffeners. If spot welds are not directly on a flange or joint, this indicates a reinforcement or stiffener is welded to the panel. The body repair manual “Replacement” section shows some internal reinforcements as a dotted line. (see figure 3)
- the repair must not be in a load bearing area such as engine, transmission, or suspension mounting points.
Also keep in mind that when sectioning 780 MPa or less, GMA (MIG / MAG) open butt welds are now a Honda/Acura approved repair method.
But what about outer body panels and floors? Per Honda/Acura, mild steel outer body and floor panels may be sectioned without specific procedures. In the body repair manual, “outer panels” refers to the 270 MPa outer body skin panels. These are generally identified with the words “outer panel” in the part name.
