Why Picking the Right Flap Disc May Greatly Improve the Aesthetics of Your Welded Joints

In this blog post we’ll go over some of the reasons why picking the right flap disc may greatly improve the aesthetics of your welded joints.

Manufacturers and fabricators operating in this sector often deal with cold-rolled steel in situations where the look of the finished product is essential.

Companies that manufacture sports vehicles and lawn tractors will also deal with a significant quantity of sheet metal in the production of their products.

When it comes to removing welds , on average, abrasives are used up rather rapidly.

The final product’s aesthetic value cannot be overstated.

The overall visual quality of the product benefits significantly from having visible welds throughout its construction.

Before going onto the painting booth, all welds should be removed to a minimum finish of 150 grit to produce a seamless look. 

Resin fiber disc, flap discs, belts, quick-loks, PSAs, and even surface conditioning material may all find usage depending on the specifics of the task at hand.

Rarely does cold-rolled steel base material need treatment for corrosion or flaws.

On the other hand, in many situations, powder coated paint clings more effectively to a base material of 150 grit finish.

As a result of this issue, several manufacturers will time-save all flat products before beginning construction.

Application Analysis

Flap discs are necessary for the majority of weld removal tasks.

There are situations in which one is preferable to the other, and there are also applications for which the other is superior.

Most fabricators utilize flap discs in the 40-grit range or more, and resin fiber discs in the 24-36 grit range.

Cutting using discs made of resin fiber will be quicker, even on curved metal.

Flap discs have a lower cut rate than conventional discs, but they provide a better finish and last longer.

Flap discs are often used to smaller, more visible welds in situations where there is a concern for an improved finishing.

Consider using either a ceramic standard abrasive flap disc grinding wheel for aluminum or a jumbo zirconia high density flap disc for metal sanding for steel, depending on the kind of metal you want to grind.

Ceramic grain flap discs of a better grade will live for fifty percent longer than zirconia grain flap discs, and they will not burn or discolor the material.

Superior quality zirconia flap discs are more effective at removing material than fiber resin metal sanding discs.

In the context of steel fabrication or manufacturing, selecting the appropriate high-performance flap discs allows you to increase not only the beauty of your welded connections but also the productivity of your operation and the longevity of the flap discs.
