Laser vs MIG Welding: Which Has Better Penetration?

This 17-minute video from Weld.com features a laboratory comparison between laser welding and MIG welding (GMAW) penetration capabilities on fillet and butt welds. Join host Rex Alexandre from the Handheld Laser Institute as he demonstrates both welding techniques and conducts cut and etch tests to visually analyze their penetration differences. Learn why laser welding provides strength, understand beam size and gas type considerations for the LightWELD XR, discover essential safety equipment for laser welding, and see how to program custom settings. The video includes practical demonstrations on ¼" carbon steel fillet welds and ½" carbon steel butt welds, along with detailed MIG settings on the PowerMIG 260. Perfect for welders interested in comparing these technologies through cross-sectional analysis to determine which method delivers superior penetration for different applications.
