Welding Wisdom for Professionals and Beginners Alike.

Diffusion welding of aluminum and copper joints uses vacuum hot pressing at temperatures between 623 K and 923 K. It involves hot compression at a rate of 0.2 mm/min for…

Aluminum welding includes several methods. The most common are Gas Tungsten Arc Welding (GTAW or TIG), known for precision and clean welds, and Gas Metal Arc Welding (MIG), which enables…

A CC pulse in aluminum welding controls amperage to reduce heat input, which prevents warping. It provides a steady current despite voltage changes. This method improves weld quality by minimizing…

Laser welding aluminum to steel uses focused heat to join the metals. It partially melts aluminum for better bonding with steel. This method maintains metallurgical integrity and combines the advantages…

Stress cracking in aluminum welding occurs during cooling due to excessive shrinkage stresses. Key factors include a concave bead profile, slow travel speed, and a restrained joint. Crater cracks, or…

To weld aluminum with a flame, start by lighting the torch. Adjust it to a “just-off-feather” flame. Preheat the aluminum workpiece to 500-600°F, particularly for thicker sections. Remember, aluminum won’t…

TIG welding aluminum, known as Gas Tungsten Arc Welding (GTAW), uses a tungsten electrode to bond aluminum sections. This technique needs careful settings, such as AC balance and frequency. It…

To weld aluminum with wire feed, use MIG welding techniques. Set correct heat and wire feed speed. A spool gun improves wire feed consistency. Prioritize safety; wear protective gear to…

TIG welding aluminum at a 90-degree angle requires careful technique. Ensure joints fit well and set the groove angle to at least 90 degrees. Maintain a steady travel speed. Use…
