Welding Wisdom for Professionals and Beginners Alike.

Aluminum GMAW (MIG) welding parameters depend on factors like wire feed speed, amperage, and voltage. For thicker materials, preheat to no more than 230°F (110°C). Typical settings use 0.030 wire…

Heat treating aluminum after welding helps restore the T6 temper. For 6061-T6, welding can reduce strength by up to 50%. Post-weld heat treatment may not be necessary if the design…

When MIG welding aluminum, use a shielding gas flow rate of at least 20 CFH. Start with 10-15 CFH. If porosity appears, increase the flow to 20-25 CFH. Avoid excessive…

High frequency (HF) welding aluminum helps start the arc without tungsten contamination. Although you can use direct current (DC) for aluminum welding, it’s not as effective. The best AC frequency…

High-frequency TIG welding of aluminum works best at 120 Hz to 200 Hz. For better arc stability, using 400 Hz is ideal. This frequency makes the arc cone tighter. A…

To heat treat aluminum after welding, heat the part to 970°F for solution heat treatment. Quickly quench it to achieve the 6061-T6 or 6063 condition. Then, perform aging treatment by…

To join aluminum tubing without welding, use aluminum epoxy glue or watertight epoxy. These bonding methods effectively bond aluminum surfaces. For outdoor safety, wear gloves and a face mask to…

To weld aluminum, use TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) techniques. Start by cleaning the aluminum surfaces well. Preheat the material if needed. Adjust your welder settings…

To prevent aluminum from warping during welding, use clamp systems every 12-15 inches for stability. Control heat input by welding slowly and at lower temperatures. Ensure proper surface preparation by…
