Using Direct Current in Welding Aluminum
The question often arises: Can aluminum be welded using direct current (DC)? While alternating current (AC) remains the conventional choice and DC comes with its inherent limitations in dealing with sensitive metals, it's indeed plausible to wield direct current in aluminum welding. However, before opting for AC or DC, it's crucial to comprehend the challenges inherent in working with aluminum. Understanding Aluminum's Properties: Aluminum is renowned for its delicate properties - it's soft, ductile, lightweight, and corrosion-resistant. These traits render aluminum a prime choice across various industries, especially in aerospace. Nonetheless, employing an inappropriate welding method can lead to complications like arc blow, burn-through, and incomplete penetration, jeopardizing the integrity of the weld.
