Tools and materials: flax nylon sheet and the corresponding size of the sticky disk grinder

Grinding target: Aluminum alloy welding scars, welding channel

Grinding effect: to achieve the effect of non-marking welding

Example workpiece: flat aluminum doors and windows

Post-weld treatment of aluminum alloy products, how to handle them manually as well as achieve a seamless welded appearance.

Aluminum alloys are often welded, and the appearance of the workpiece is very much affected if the weld channel is not well treated.

The usual sanding method is to use the stick-on sandpaper with the sanding machine after many times of sanding, as well as switching the use of different grit sizes to achieve the effect of sanding the weld channel.

Or use the louver, for sanding treatment.

Sandpaper grinding force is relatively strong, not only requires a certain degree of technical experience, but also requires very good control, in order to make the workpiece grinding does not damage the product.

We recommend the use of flax nylon pads for grinding.

The nylon material has very good softness, which can ensure that the material of the workpiece itself is not damaged while grinding.

The abrasives coated on the surface give it excellent cutting and grinding ability.

Different colors correspond to different grain sizes, but in general, for grinding aluminum alloy, a certain type can be used to grind smooth.

Then it can be polished and brushed.

It doesn’t take much effort to control the strength, and after the visible black weld path disappears, it’s done.

The polished workpiece is so flat that you can hardly see the welding traces.

Linen nylon sheet, also known as non-woven nylon sheet, its material principle is similar to that of Pepcid, but has better cutting power than Pepcid.
