Spray vs Short-Circuit vs Pulsed MIG What Are MIG Transfer Modes? MIG transfer modes describe how molten filler metal moves from the wire electrode into the weld pool during MIG (GMAW) welding. The selected transfer mode directly affects: Heat input Penetration Spatter Bead appearance Welding position capability The three main …

Hydrogen Cracks in Steel: Causes & Prevention Hydrogen cracks in steel — often called hydrogen-induced cracking (HIC), cold cracking, or delayed cracking — is a stealthy enemy in welding and metal fabrication. It can appear minutes, hours, or even days after welding, seemingly out of nowhere, and cause brittle fractures …

BackStep Technique for Tig Welding Thin Metal TIG welding thin metal demands a surgeon’s touch: tight control of heat input, steady hand movements, and a welding sequence that prevents the plate from becoming a warped pancake. The backstep technique is a proven method to limit longitudinal distortion in thin-sheet TIG …

What Causes Welding Spatter? Welding spatter is caused by unstable molten metal droplets being ejected from the arc or weld pool. The instability arises from a combination of incorrect process parameters, consumable or base-metal contamination, poor shielding or gas flow, equipment faults, and operator technique. Fundamental physics of arc metal …

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 …
