In-situ Process Temperature Monitoring

If you want to keep an eye on the temperature during welding, use a thermal imaging device or a temperature stick and measure directly at the weld seam or in the heat-affected zone. If the part gets too hot, you change the structure, the material becomes hard and brittle, and you risk cracks. So: better let it cool down in between and keep an eye on the temperature, then you avoid burning the material and a bad weld.
