1. Welding can indeed join iron and aluminum together.
2. The choice of welding wire that is suitable for welding dissimilar metals like aluminum and iron is crucial.
3. In the right environment and without special requirements, welding iron and aluminum is feasible.
4. For instance, it is not difficult to weld tubular sections of aluminum and steel structures after proper preparation.
5. Corner joints or overlapping welds can be successfully made with careful fitting.
6. However, welding iron plates and aluminum plates flush against each other presents a greater challenge.
7. Aluminum-to-steel welding often employs a filler metal such as WEWELDING-Q303B, conducted at a working temperature of 400 degrees Celsius through soft soldering.
8. The filler metal exhibits good capillary action, especially with tight fits.
9. But soldering cannot match fusion welding in terms of overall performance, such as tensile and shear strength.
10. Consequently, there may be shortcomings in terms of shear resistance when soldering aluminum and steel flush joints.
11. For thicker plates, flush face-to-face welds between aluminum and iron can be achieved with specialized equipment.
12. When referring to "steel," it is a general term that can mean common iron (wrought iron) or stainless steel.
