Side-by-side comparison of MIG welding and TIG welding

MIG vs TIG Welding: How to Choose the Right Method

According to the 2024 Bureau of Labor Statistics, over 424,000 welders work across the U.S. MIG and TIG dominate this massive industry. These two electric arc processes use shielding gas to melt and join metals, but their specific techniques, travel speeds, and final weld qualities dictate entirely different use cases.

Types of Casting: Which One Should You Choose

According to a 2023 China Foundry Association report, factories produced nearly 52 million tons of metal castings. U.S. steelmakers used over 41 million tons of scrap just to keep up. Demand is high because metal components need to be strong and cost effective to make. But with the global market
