DC TIG welding of aluminum uses direct current with argon as a shielding gas. It requires electrode negative (DCEN) settings. Cleaning the aluminum surface removes the oxide layer. For improved results, adding helium gas can enhance penetration and weld quality in aluminum joints. Heat management is also crucial for successful welding. Another technique involves selecting … Read more

To weld thick aluminum (3/8 in. or thicker), set the AC frequency between 80-120 Hz. Use 1 amp for every 0.001 in. of thickness. For instance, for 0.125 in. aluminum, you need 120 amps. For thicker materials, adjust the amperage and increase the frequency to 120-200 Hz for the best welding quality. Using the aluminum … Read more

Chronic exposure to aluminum welding fumes can cause pneumoconiosis, a serious lung disease. This condition leads to reduced lung function and pulmonary accumulation of particles. It was previously called Welder’s siderosis due to the presence of iron oxide in the lungs. Implementing safety measures is crucial to prevent these respiratory effects. Welders should adopt protective … Read more

Use the aluminum filler metal selection chart to choose the right filler metal for welding. The chart shows characteristics like weld strength and fluidity. It includes recommendations for gas shielded arc welding and oxyfuel gas welding. Alloy 4047 improves fluidity and reduces cracking, creating strong weld joints. When selecting a filler metal, consider the base … Read more

Short-term exposure to aluminum welding fumes can cause dizziness, nausea, and irritation of the nose, throat, and eyes. These fumes may contain toxic substances like carbon monoxide and nitrogen dioxide, leading to metal fume fever. Always use proper safety measures to avoid risks like electric shock and skin burns. Exposure to aluminum welding fumes can … Read more
