Aluminum Welding

Welding steel to cast aluminum using arc welding is difficult. The high heat can form brittle intermetallic compounds that weaken the joint. To tackle these challenges, consider using filler materials or adhesive bonding. This approach helps manage the different material properties and prevents structural failures. However, challenges remain in achieving strong weld joints. The differences … Read more

The welding shade chart for aluminum shows the right lens shades for different amperages. Use shades #5 to #8 for lower currents (80-100 A). For higher currents, choose shades #10 to #14. Refer to OSHA and ANSI for safety standards. Remember to adjust your shade based on your welding technique, whether it’s MIG, TIG, MMA, … Read more

Welding stress in aluminum is the residual stress that forms during welding. When aluminum melts and solidifies, it shrinks, causing stress around the weld. Post-weld stress relief is often not recommended. Machining can increase distortion and affect dimensional stability, leading to further issues in the welded part. Best practices in welding aluminum focus on minimizing … Read more
