Whether you talk about a manufacturing process or a fabrication process, welding happens to be a crucial step in both the processes. Different types of metals are welded for several types of fabrication. (www.treerush.com) It is important for you to know that in order for a welding process to be effective and accurate from the first instance, the parent material should be properly prepared.

It is needless to say that material preparation is rather critical. In fact, the preparation is often documented to make sure that it is consistent whenever required irrespective of the material itself. Getting rid of various coatings, such as oils, paint, grease, and oxides, including rust, from the area that needs to be welded, will ensure that it is in the optimum condition for the process.

Useful Tips for Mechanical, Manual Cleaning
If you are planning to use a nonferrous or stainless power brush for the purpose of weld cleaning, it will be advisable to run it at a very low speed. The speed should range between 1250 and 4250 SFPM or surface feet per minute. It will also be good for you to know that stringer bead wheels that also includes those variants that come with a reversible twin-nut feature will usually provide an even and effective cleaning, as well as, an excellent operator control for cleaning carbon steel fillets in between welding passes.
Another one of the several critical components of proper weld cleaning and preparation is the operating speed. It is important for you to remember the thumb rule, “slower is often faster,” while preparing a surface for the purpose of welding. If you use slow speeds in order to control friction, it will actually help in the reduction of the weld and surface area contamination.
High surface contact speed can easily generate a good amount of vibration that can cause the brush tips or the abrasive material to skip over surfaces. As a result of this, impurities will remain where they actually were. There is also the fact that fast operating speeds can easily reduce your control over the tool so be sure to visit site to see the limitations.
Best Practices
If you wish to obtain the best overall performance of any product that is used in the preparation of a weld surface, it is always wise to calculate and also control the speed, as well as, the friction that are applied to the surface. It will be a good idea to consult with the recommendations that are provided by the manufacturer for maximum RPM.
It is also advisable to avoid creating deep scratches or getting rid of too much of the parent material around the weld area. This will simply result in poor arc control or inclusions during the entire welding process.
Another factor to avoid is cross-contamination with the help of clean and new abrasive product. It is needless to say that contamination can easily occur either directly or indirectly. Direct contamination can easily be prevented as long as you keep your consumables organized and separate. These consumables are for nonferrous and ferrous materials.
