Recommended General Motors Steel Repairability Matrix

Posted on 9 February 2015

The Recommended GM Steel Repairability Matrix is a chart that identifies GM’s repair recommendations according to the type of steel that the part is made from. The matrix contains information on the steel identification stamping symbols, steel grade, GM specifications, recommended welding methods, cold repairability, use of heat for repairs, the temperature range that should be used, and the maximum heat allotment. The second page of the matrix is a chart of Descriptions of GM Steel.

Restraints System Wiring Repairs

Posted on 6 February 2015

19565Figure 1 - These crimp and seal splice sleeves have special heat shrink sleeves on each end that shrink around the wire and form an air-tight seal.Confusion exists within the collision industry concerning the repair of some damaged wiring and wiring connectors for restraints systems. The perception is that restraints system wiring should never be repaired. While it is true that some vehicle makers do not recommend the repair of wiring and connectors for the restraints system, others have very detailed printed procedures and even offer repair kits expressly for the repair of restraints system wiring. Repairing damaged restraints system wiring, when applicable and the parts and procedures are available, can save unnecessary replacement of the main body and instrument panel wiring harnesses.

Today’s Advanced Vehicles Require Changes in Collision Repair Attachment Methods – Part 1

Posted on 20 December 2014

This article originally appeared in the November/December edition of Fixed Ops Magazine.

Collision repair professionals are no different than any other professional – we are resistant to change. It took many years for repairers to make the switch to “MIG welding” for welding early unibody vehicles. (For this article we’ll use the term gas metal arc welding (GMAW) metal inert gas (MIG), or GMA (MIG)). (More on the reason, later.) It was a technology that was unfamiliar to many and there wasn’t a perceived need for change. History would prove otherwise, as there may not be a collision repair business in the country that doesn’t have a GMA (MIG) welder.

Repair or Replace? – Material Tensile Strength Key to Repairability

Jason Bartanen, I-CAR Director, Industry Technical Relations

The world of steels continues to evolve at a rapid pace and repair professionals need to keep up. In order to perform complete, safe, and quality repairs, it’s imperative to identify the type of material we’re working with, to know what is repairable, and know which options we have for part replacement when straightening is not an option.

Strategy Based Diagnostics In Collision Repair

Posted on 19 September 2014

by Chuck Olsen, Collision Diagnostic Services (CDS)

Strategy Based Diagnostics is an automotive best practice routine that was initially published by GM after studying and observing successful technicians in the field who consistently meet or exceed productivity standards with the lowest levels of "re-checks" or "comebacks." Since GM published this best practice, Strategy Based Diagnostics has been adopted by most in the automotive repair field.

General Motors Overlap Sectioning Joint

Posted on 31 May 2012

Until recently, General Motors has generally specified butt joints with backings when sectioning parts of a uniside. However, an overlap joint is now being required for some uniside sectioning joints. This is being done to reduce the transfer of heat from GMA welding into heat-sensitive high- and ultra-high-strength steel reinforcements. The concern with a butt joint with backing is that the backing piece does not extend to the pinchweld flange, and leaves the reinforcement exposed. As a result, a GMA weld is made on the pinchweld flange area of the reinforcement (see Figure 1).

Three-Dimensional Measuring Equipment - Is It Really Necessary?

Posted on 8 September 2011

I-CAR has been emphasizing the importance of three-dimensional measuring since its founding in 1979, but is it really required to repair a vehicle?
