Khi hàn tấm nhôm dày 2mm 5052 đến 6063 hợp kim sử dụng hàn TIG, một sự lựa chọn phù hợp cho dây phụ thường là 5356 hợp kim nhôm. Dưới đây là những cân nhắc chính:
- Khả năng tương thích hợp kim: 5356 được thiết kế để hàn các hợp kim nhôm dòng 5XXX, mà bao gồm 5052. Nó cũng thích hợp để hàn các hợp kim nhôm khác nhau, thích 5052 đến 6063.
- Thành phần hóa học: 5356 contains higher levels of magnesium, providing good strength and corrosion resistance. This composition is suitable for welding 5052 and is also compatible with 6063.
- Welding Characteristics: 5356 filler wire offers good flow characteristics during welding, making it easier to handle. It provides good strength and ductility to the welded joint.
- Ứng dụng: 5356 is commonly used for general-purpose welding of aluminum where high-strength welds with good corrosion resistance are required.
Before welding, ensure that you thoroughly clean the aluminum surfaces to remove any oxides, dirt, or contaminants. Cũng thế, make sure your welding equipment is set up for TIG welding aluminum, and use a high-purity argon shielding gas.
Always follow the specific recommendations from the filler wire manufacturer, and consider performing a test weld on scrap material to fine-tune your settings and techniques before welding the actual project. If you have any specific requirements or concerns, consulting with welding professionals or experts can provide valuable guidance.
