Aluminum Welding Skills and Aluminum Profile Processing Process-WJW Aluminum Supplier Aluminum

Aluminum welding 5 techniques.

1. Those who are more suitable for welded aluminum are brushed welded welds. If you cannot use this type of welding, try to use a short welding torch to keep the stroke of the welded gun. When welding machines), you can only use the gun method.

2. If you find that there is a wire delivery problem, you can try the conductivity of the size larger than the welding wire.

3. The welding wire when welding aluminum is softer -welded welding wire, and the other is a harder (easier to send wire). It is mainly used in welding operations with higher hardness and strength requirements.

4. Before the start of the welding, do the removal of the oxidation layer of the aluminum material, and use a special stainless aluminum steel brush to remove the oxidation layer.

5. Fill the arc pit at the end of the welding to prevent cracks. One way is to stay in the molten pond after welding.

Aluminum profile processing process.

(1) Pickling the order:.

After receiving the processing form, the operator must understand the meaning of the map and review whether the data referred to in the figure is consistent with the single -related data.

Under the condition of anastomosis, the materials plan and go through the procedures for the collection.

(2) Receive :.

According to the material model, specifications, and color, the color of the library is approved after the signature, and the materials are verified according to the number of single quantities.

First check the appearance quality of the aluminum profile. The surface of the profile must not be corroded, oxidative defects and severe scratching. The scratching deep aluminum materials must not be greater than the surface treatment layer thickness.

(3) Cutting:.

The cutting angle is 22.5 22.5 , it needs to be scheduled, processed by line, curved the arc profile, if cut 90 , you need to scratch and process it by line.

Cutting size allows deviations to meet the requirements of design drawings.

(4) Drilling, milling:.

When drilling the hole, you must use the punch to hit the nest at the hole position. When the drilling position is not a plane, it should be adjusted to the plane before processing. When drilling the blind hole, you should use the drilling machine ruler or at the drill headhole cover. On the upper positioning ring control hole depth, when the holes that are frequent, when drilling 6mm, starting into the pores and fast drilling, you must be light to the strength. When it is a piece, the support should be padded below. The coolant should be sufficient when drilling.

Under the condition of not affecting the shape of the processing, try to use a large diameter milling cutter. When the milling is closed, first drill a craft hole. Milling the guide rod determines the size of the template, manufacture the template, you need to adjust the positioning rod to determine the processing position. When using the end -of -end milling processing, you must adjust the positioning of the top block and the height of the saw blade, and the aluminum material.
