Spot welds are used to connect two pieces of metal. They are cheaper and easier than other welding methods but require a special technique. In this blog post, we will teach you the basics of how to drill spot welds so that you can start practicing on your own!
How to Drill Spot Welds: Easy Steps For Beginners
There are a lot of good reasons to learn how to drill spot welds. Here we will provide you with the steps in an easy-to-follow guide.
Step 1: The Right Tools
The first step in this process is to gather the right tools for the job. You will need a drill, a small grinding bit, and cutting pliers. A vice might also be helpful when you are working on your car.
Step 2: Clean the Area
Before you begin drilling, it is important to clean off any paint or rust on your vehicle’s body panel where you are going to drill. If there is still some oil or grease present, this will cause a problem with finding and holding a place for your small grinding bit when we get further into the process in Step Three.
Be sure that you remove all dirt and dust from both surfaces before beginning to work. Otherwise, it can be difficult, if not impossible, to find good ground contact between these two pieces of metal.
Step 3: Find The Spot And Mark It
You will now want to find the place where you are going to drill. Once again, make sure that both surfaces are clean and free of rust or paint before continuing on with this process. Hold your metal in front of a light source so you can see through it clearly and determine if there is any gap between these two pieces of sheet metal.
If there does not appear to be a break, you might need another person’s assistance because he/she should have better eyesight than yourself when trying to spot welds from various angles while looking for breaks in the surface itself around all four sides.
When everything is clear, use a marker pen to outline exactly where your future drilling is going to take place. Once you have identified the spot, make certain that it is your final decision before moving on because once this mark has been made, there will be no turning back until you complete the task at hand successfully.
Step 4: Drill It Out!
Now it’s time to get started with drilling itself. Be sure that everything is securely in place where I don’t want any accidents or injuries while putting power behind your drill bit here so please use caution and let someone know what you are doing if possible just for safety purposes because we wouldn’t want anything bad happening to anyone reading these instructions now, would we?
To start off, work slowly around all four sides of your outline marking where holes should be placed about half an inch deep for the first few rounds. Then you can go back over these holes with a smaller grinding bit to make them more defined and easier to see where they are at this point of the process.
Now that your outline is complete, it’s time to get down to business by aiming your drill directly on top of each one of those small holes, which will now become spot welds themselves after drilling has been completed successfully.
Turn up your power source all the way, so there isn’t anything holding you back from achieving good ground contact between both surfaces here before moving forward in Step Five.
With everything ready, press down firmly but not too hard, or else you might end up stripping off some paint instead while using even pressure across the entire surface area being drilled out here.
Please note that you might want to consider using a lubricant of some kind on the drill bit before beginning, or else it can end up overheating and lose its original shape due to friction while the drilling process is in progress which will cause problems down the road when we get into welding phase itself.
Step 5: Let’s Weld!
Once everything has been successfully drilled out, then this step becomes much easier than what it was like during previous portions of the instructions here so congratulations are in order for meeting expectations so far and not giving up even once at any point throughout these steps because we know how frustrating things can sometimes be even though we don’t mean to make life more difficult than necessary without a good reason behind doing so ourselves.
It just comes with the territory sometimes, and we all must accept responsibility for those things that happen in our lives as a result of making poor decisions along the way.
Now, it’s time to move ahead with the welding process itself where you will need at least one helper, or else this task can prove challenging by yourself especially if you haven’t done much work like this before today so be sure to ask around first before attempting anything here without any assistance whatsoever because there is safety in numbers folks, always remember that!
Make certain to weld both sides together completely but do not worry about going overboard either because too much heat from arc-welding equipment can end up warping metal surface being worked on after all has been said and done, which means more work needs to be done later on down the road in order to get it back into original shape again.
As long as everything is done properly, you shouldn’t run into any problems like that while the welding process itself has been completed successfully, which means only one thing.
Step 6: Done!
Now, all there remains for us to do is let our newly welded spot welds cool off completely before attempting anything else here because once they are no longer hot or usable anymore than we can go ahead and pull them apart with relative ease until next time when doing this project ourselves sooner depending on your own personal timetable regarding these things.
