Structural Sectioning Procedures: General Motors

Posted on 22 March 2017

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 General Motors (GM) says about structural sectioning.

Weld-through primers are generally a zinc-based product that is applied to the mating surfaces prior to welding. Corroding zinc forms zinc oxide, which protects the steel. This is called sacrificial corrosion. For a quality weld to be made it’s required that the weld-through primer be removed from the direct weld zone before welding the joint, when MIG welding. Many OEMs have a position on when and how to use weld-through primer or when it shouldn’t be utilized. Let’s see what Fiat Chrysler Automobiles (FCA) recommends and where this information can be found.

Inside the Aluminum Revolution: Factors to Consider When Upgrading - SCRS Press Release

Posted on 4 March 2015

Originally appeared as a SCRS Press Release

Prosser, Washington, March 4, 2015 - Not since the introduction of the unibody vehicle has there been as revolutionary a topic to hit the collision repair industry as aluminum repair. With more and more cars and trucks equipped with this innovative material - as well as tools, products and equipment specifically designed for them - entering the market every day, the debate on how and with what to best perform proper aluminum repairs rages on. The Society of Collision Repair Specialists (SCRS) recently sat down with representatives from the equipment and tooling sides of the industry, as well as several collision repair facilities who have taken the plunge of upgrading, to get their perspectives on repair safety, the importance of accurate information and their personal experiences on the front lines of the aluminum revolution.

Restraint 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 restraint systems. The perception is that restraint 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 restraint system wiring. Repairing damaged restraint 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.

Advanced Joining Methods For Todays Vehicle

Posted on 31 October 2014

This article originally appeared in the November 2014 edition of ABRN.

When friends and family think about the vehicles of yesteryear they often say to me "they don't build them like they used to." I tell them, you have no idea how right you are. Cars today are light years ahead of where they were just a few short years ago. It is no longer vehicles of the future we are discussing, but current vehicles on the road today, and some are being repaired like nothing has changed. With the major changes in vehicle construction, the collision repair industry will need to learn some advanced attachment methods and a new way of thinking. Lets take a look at some advanced attachment methods necessary for repair on vehicles that are on the road today.

Is it MIG or is it MAG?

Posted on 7 October 2014

Once people get used to calling something one thing, it's difficult to change it. To be technically accurate, whether it's MIG or MAG depends on the shielding gas.

When GMA (MIG) welding started its rise, it was often referred to simply as MIG welding. While this term is widely known, it's not technically accurate. MIG stands for "Metal Inert Gas" and is accurate when making welds using an inert shielding gas, such as 100% argon when welding aluminum. However, for most collision repairs on steel parts, we use a shielding gas that is 75% argon, 25% carbon dioxide (often called 75/25, or C-25). Because carbon dioxide is an active gas, the correct term would be metal active gas (MAG) welding.

What's Iowa Got to Do With It?

The Aluminum Difference

by Jason Bartanen, Director, I-CAR Industry Technical Relations

We've seen a lot of changes in vehicle technology over the years. With each of these changes come new challenges and new opportunities. When the unibody vehicle was introduced, repair professionals were required to change their approach to collision repair, from damage analysis through the repair process. With the introduction of GMA (MIG) welding, additional requirements for repairs included new training and equipment. And passive restraint systems presented a completely different type of challenge, involving electronics and diagnostics.

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 (MIG) 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 (MIG) weld is made on the pinchweld flange area of the reinforcement (see Figure 1).
