Car Restoration: Welding Tips for a Stronger Frame

January 27, 2012

You must bear in mind a few car restoration and welding tips when working on your vehicle. This will not only allow you to complete the task with relative ease, but also leave you with great results. If you’re a beginner working on car restoration, you should consider purchasing a car restoration guide, to help you learn the basics of welding. Before you actually start welding the frame, you must follow a few principles that will help you complete your welding project. Most welding projects adopt the MIG welding principles. When using a MIG welder, you need to create the right balance of voltage, current and resistance. In order to attain this balance, you might have to practice welding a piece of metal that’s similar to the metal frame, you want to work on.  Since there are different techniques used to weld metal, you need to also determine which technique is suited to the type of metal you’re welding.

Right Technique

You need to hold the tip of a gun at a right distance from the frame you’re welding. If you discover that you’re blowing holes into the metal, increase the distance between the tip of the gun and the metal, so that it creates resistance. In order to avoid burning the metal you should adopt the ‘pull’ technique. However, you may use a combination of different techniques when working on a single seam. Remember, the key to a good welding job is careful adjustment of the welding speed and gun distance from the metal.

Welding Thin Sheets

If you’re welding thin sheets, you need to prevent distortion. The easiest way to attempt this is to weld small sections at a time. Allow these sections to cool before you work on surrounding areas of the surface. Since distortion occurs due to overheating of the metal panel, you have to weld thin sheets at intervals, so that the panel cools down before you start working on it again.

Other Tips

When welding any particular part of the car, you need to make sure that you protect surroundings areas from sparks. These sparks could cause significant damage to the other areas of the car, including the windows. Consider using a welding and spark deflection paper that would completely protect the exteriors. Also keep an angle wire cutter at hand when carrying out any welding job. This will allow you to cut the wire at regular intervals, so that you get a sharp tip to penetrate the metal. Once you’ve completed the welding job, you need to grind the weld so that you even out rough surfaces. This will also ensure a good paint job. Remember to work slowly when grinding the weld, so that you don’t create pits or depressions. Since welding could cause dangerous burns, you also have to make sure that you wear the right clothing and protective gear, before starting off.

If you’re working on a welding project for the first time, you may want to take the help of a trained mechanic so that you learn the right techniques for car frame restoration. Moreover, it’s important to keep in mind the basic principles of welding, in order to weld a strong frame that lasts many years.
