Welding on the chassis of a computerized Porsche

Sometimes it becomes necessary to weld on the body or chassis of your Porsche. This would usually be part of a repair following an accident but could also be non accident related repairs or modifications that would require welding to be performed somewhere on the car. We are specifically concerned about using the different types of electric arc welding. These include Stick, MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding also known as Heliarc welding. All of these electric arc welding types use electrical energy (either A/C or D/C Voltage) to generate extreme heat at the localized spot where the weld is taking place. As part of the welding process, an earth connection (welder ground) is made near the welding site to isolate and collect this energy during the welding process; however, not all of the electrical energy will necessarily take this path. High frequency electrical energy can be introduced into the car’s grounding and wiring systems through th ... read more
