Properly preparing metal prior to welding is a very important step in the welding process. If the metal you are welding is not properly cleaned you can compromise the integrity of the welds. Properly cleaning the metal takes time but it is worth the effort to insure that your welds are of the best quality and integrity. Below are some steps to follow in order to properly clean the metal you will be welding.
- The first thing you should do is to check the metal before you weld it. If there is any type of coating on the metal, which may be a thin layer of metal, you should remove it. To remove any coatings or metal that is on the surface you can either use a grinder or chemicals to thoroughly remove the coatings.
- When preparing metal for welding it is also important that you remove any rust that may be on the surface. It is common to find rusty spots when dealing with car metal. To remove any rust from the surface of the metal you can use a grinder or steel wool.
- As you are preparing metal for welding you can try different techniques to find the one that works best for you. You can take this time to try straight or flat grinders to see how they work in removing coatings from the surface. If the metal you are preparing consists of different shapes or angles you should use an angled grinder.
- If there are any bad welds on the metal you are preparing now is the time to remove them using a grinder. Removing a bad weld and creating a new one is often better than trying to repair a bad weld. Starting with a clean slate means that you can create a weld that will be strong.
- You should use a grinder to clean the edges of the metal you will be joining. Having clean edges insures that the weld you create will be solid and strong.
- Whenever you are preparing metal for welding you should always wear a pair of safety glasses to protect your eyes from any debris. Having a metal shaving land in your eye can be very dangerous and even cause permanent damage to your eye.
Once you have properly cleaned your welding material you are now ready to begin. When welding you should always wear the proper safety equipment to guarantee you stay free from burns and other injury.
