Today’s Advanced Vehicles Require Changes in Collision Repair Attachment Methods – Part 1
Posted on 20 December 2014This 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.

Is There a Procedure for Disassembling a Service Assembly?
Posted on 19 June 2014The fourth column in the OEM Technical Information Matrix, Partial Service Part/Assembly Replacement Procedures at Factory Seams, can get a little tricky without further clarification. For the most part, this is a column that I-CAR is still researching published OEM information to get the answers to. The question is: Does the vehicle maker have procedures for replacing a partial service part or assembly at factory seams?

Can You Section A General Motors Vehicle Without A Procedure?
Posted on 28 March 2014Did you know that in 2013, General Motors published a position statement that identifies that sectioning should only be performed in recommended areas? This warning is applicable to all GM lines including Buick, Cadillac, Chevrolet, and GMC.
General Motors eAssist Electric System
Posted on 11 October 2012Another version of electric-assist vehicle technology is showing up in collision repair facilities. General Motors in 2012 introduced what it refers to as "light electrification" technology on select models. This system is called eAssist, and is available on some 2012 Buick LaCrosse, Regal, and 2013 Chevrolet Malibu models (see Figure 1).
General Motors Overlap Sectioning Joint
Posted on 31 May 2012Until 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 2011I-CAR has been emphasizing the importance of three-dimensional measuring since its founding in 1979, but is it really required to repair a vehicle? After all, three-dimensional measuring systems are considerably more expensive compared to the much more affordable tape measure or tram gauge (see Figure 1).
