CONCEPT OF INDUCTION HEATING
INDUCTION VS. FLAME
Until recently, open flame remained the pr
Open flame heating lacks precision and presents safety risks in steel fabrication.
Induction heating provides a safer, more controlled solution for preheating and PWHT.
- Uniform heat
- Better weld integrity
- Higher efficiency
- Improved safety
Induction-based PWHT ensures consistent performance in structural steel fabrication.
imary pre-heating method in the industry. Since safety is a major concern while using an open flame, Thermal Tech & Temp has developed a much safer, energy-efficient, and cost-effective method for heat treatment. Now, Miller ProHeat35 induction heating system in conjunction with Thermal Tech & Temp’s induction accessories sets the bar in the welding/fabrication & construction industry. Whether you are looking for preheating of welds, post-weld heat treatment, coating removal, or shrink fit, our accessories can do it all!
Limitations of Open Flame Heating
Open flame heating lacks precision and presents safety and efficiency challenges in steel fabrication.
- Safety risks from fumes and combustible gases
- Uneven temperature control
- Slow heat-up and high fuel costs
- Excessive heat exposure for operators
Structural steel PWHT demands controlled and repeatable thermal performance—best achieved through induction heating technology.
