Welder PPE for Fumes Reduction Welding fumes are tiny airborne particles produced whenever metals are melted. For welders, those particles are the invisible hazard that accumulates in the breathing zone and, over time, can produce both immediate and long-term health effects. Controlling fume exposure is therefore a primary safety responsibility …

Understanding HAZ in Aluminum Welds The Heat-Affected Zone (HAZ) is the unseen neighborhood around a weld where temperatures from the welding process change the metal’s microstructure without melting it. In aluminum welding the HAZ frequently controls whether a joint will meet strength, toughness, or corrosion requirements — more than the …

Welding Super Duplex Stainless Steel Super duplex stainless steels (SDSS) sit at the high-performance end of stainless metallurgy: they pair very high strength with excellent resistance to localized corrosion (pitting and crevice) in chloride-bearing environments. Because of that combination they’re widely used in aggressive process environments — think oil & …

How to Choose Shielding Gas for GMAW and FCAW Choosing the correct shielding gas is as important as selecting the right wire or welder settings. The gas directly controls arc behavior, heat input, penetration, spatter, and — ultimately — weld quality and mechanical properties. For GMAW (Gas Metal Arc Welding, …

Globular Transfer in MIG Welding Globular transfer is one of the classic metal-transfer modes encountered in Gas Metal Arc Welding (GMAW), commonly called MIG (Metal Inert Gas) welding when inert gases are used. It sits between short-circuiting transfer and spray transfer in both behavior and effects: the molten wire forms …

Welding Stainless to Carbon Steel Welding stainless steels to carbon (mild) steels is one of the most practical — yet metallurgically tricky — tasks a welder faces. The join is common in piping, heat exchangers, exhaust systems, and many retrofit repairs where corrosion resistance is needed only on one side …
