Welding aluminum using gas metal arc welding (GMAW) is gaining popularity because it’s versatile, efficient, recyclable, and produces strong, clean welds. Aerospace, automotive, shipbuilding, manufacturing, and energy sectors need skilled aluminum welders—and they need them now. Aluminum 6061

Experimenting with aluminum GMAW pulse settings

Knowing when and how to use the pulse setting is a start, given aluminum’s high thermal conductivity and susceptibility to distortion. Pulse involves alternating between high-current pulses and low-current background settings. Pulse welding controls heat input, reduces distortion, and improves the overall weld quality.

Understanding the following settings will help you to dial in your machine properly:

Anyone who welds aluminum regularly knows the following, but these points are worth repeating:

Pulse settings can vary depending on material thickness, joint design, and desired bead profiles. Consult welding procedure specifications, manufacturer guidelines, and experienced welders when setting aluminum GMAW pulse parameters
