Therness is in Chicago for IMTS 2026, 14–19 September at McCormick Place, and meeting welding-intensive manufacturers across the Midwest. What we bring to US shops and how to meet us.
A frame-by-frame read of the CMT dip-retract cycle at 480 fps: six visible phases, and what a stable and a broken cycle each say about heat input and spatter.
Delayed hydrogen cracking appears hours after the arc stops. How to set a defensible inspection hold time and prove the joint cooled the way you planned.
Emissivity is the biggest error source when a thermal camera measures a steel or aluminium weld. How to set it, reference it and prove it on real parts.
Fillet weld size chart in mm explained: leg versus throat, where 0.707 comes from, how American codes set a minimum from the thicker part, and a worked method.
How infrared thermography measures forging die temperature in production: emissivity, camera siting, verification and the failure modes that fool the data.
Where thermography earns its place in a foundry: ladle shells, pouring streams, mould faces and knockout, plus the emissivity traps that fool the readings.
How to compare weld thermal signatures side by side: an even trailing plume, a hot spot, or an asymmetric pattern, and how to verify what you see.
How to identify GMAW transfer mode — globular, spray, short-circuit — from high-speed footage, the parameters behind it, and how to verify the call.
