welding thin aluminum sheet metal
(1) flame selection
Welding flames require neutral flames or slightly carbonizing flames. To prevent the oxidation of aluminum, the use of oxidizing flames is strictly prohibited. The size of the welding nozzle should be determined according to the thickness of the sheet. Aluminum sheets burn through easily. You can choose a welding tip that is one size smaller than that of low-carbon steel, and thicker welding parts dissipate more heat, so you can select a larger welding tip.
(2) Tack welding
It is to fix the relative position of the weldment and prevent deformation. It is necessary to tack weld the weldment. The positioning spacing of the sheet thickness less than 1.55mm is 10~20mm; the positioning spacing of a sheet thickness of less than 5mm is 30~50mm.
(3) Preheating before welding
For thin and small aluminum parts, preheating before welding is not required with minor stiffness. For weldments with a thickness greater than SMM, it is necessary to preheat the weldments to 200-300 °C to reduce welding deformation and welding cracks.
Welding technique of thin aluminum sheet
(4) Welding operation requirements
① During the welding and heating process, continuously dip the tip of the wires with solder powder to temporarily move the surface of the heated area. If it feels sticky and the molten wires can fuse with the weld metal, the temperature at which the weld pool will form has been reached and welding can proceed;
② The left welding method can be used to weld thin and small weldments to prevent overheating and burning through;
③ The movement of the flame is to move up and down, the welding wires is always in the front of the molten pool, and there is a slight up and down jump, which is opposite to the effect of the flame. Do one weld at a time. When interrupted, the joints should overlap by 20~30mm;
④ Try to avoid multi-layer welding of aluminum alloys, otherwise, the joints have large grains, pores or cracks that are prone to occur, and the welding seam is poorly formed.

About 0.8 thin aluminum sheet
There are certain welding difficulties in traditional fusion welding of thin aluminum sheets.
Suppose the thin aluminum below 0.8mm must be welded by conventional fusion welding such as argon arc welding. In that case, the focus is on the equipment, the small current output of the equipment, and the stability under small current output. This can refer to Viodin ultra-thin aluminum welding machine.
If it is larger than 0.8mm and 0.8mm, it can be welded with a conventional aluminum argon arc welding machine power supply by intermittent spot welding and wires feeding
0.8 thin aluminum sheet
Of course, some thin aluminum parts with special shapes are not convenient for fusion welding and require low-temperature welding. The welding heating heat source adopts the third-generation derivative liquefied gas spray gun. The flame is relatively dispersed and insufficient to burn the substrate. According to the temperature range, the welding wires can be divided into 179-degree welding, M51385-degree welding, 53-degree welding, and 303-degree welding
The main welding principle of low-temperature welding: is mainly formed by transferring the heat of the base metal to the molten welding wires.

Aluminum sheet sheet standard export packing
- The aluminum sheet is paperclip or laminated to ensure that the surface of the aluminum sheet is intact and free of scratches;
- Plastic film ( HDPE, PVC, PE or PET etc ) protection or hard kraft paper wrapping is used to prevent moisture and rain to ensure that the aluminum sheet is clean and free of dirt during transportation (each package has a moisture-proof desiccant to ensure the quality of our prodsucts in East China and South China, where there is more rain);
- Installed with wooden brackets and reinforced with steel straps to avoid collision during transportation and to ensure the geometry of the aluminum sheet remains unchanged;
- For export prodsucts, we use wooden boxes and pallets with fumigation mark for packaging;
- We can also pack according to other packaging requirements of customers;
