1. Galvalume steel sheets can form strong welds during welding. The aluminum-zinc layer on its surface will interact with the base material under high temperature to form a special alloy layer, which helps to improve the strength and toughness of the weld and reduce the risk of weld cracking and falling off.
2. Galvalume steel sheet has strong welding adaptability. Whether using traditional arc welding, gas shielded welding, or newer laser welding methods, good welding results can be achieved. Different welding processes can be selected according to specific welding requirements and workpiece characteristics to achieve the best welding quality.
3. The welding process of Galvalume steel sheet is relatively stable. The changes of the aluminum-zinc layer in the heat-affected zone of welding are relatively controllable, and serious oxidation, dezincification and other phenomena will not occur, thus ensuring the continuity and stability of welding. This makes welding operations easier to control, improving productivity and consistent weld quality.
4. When welding Galvalume steel sheets, some issues need to be noted. For example, the welding parameters should be selected appropriately. Too high a welding temperature or too long a welding time may cause excessive burning of the aluminum-zinc layer or welding defects. In addition, post-welding treatment is also important, such as timely cleaning of welding slag and oxides in the welding area to prevent corrosion.
