Increasing your Shop Floor productivity with SigmaWeld Pre/Post Weld Heat Treatment

In today’s fast-paced manufacturing industry, increasing shop floor productivity is
critical to staying competitive. One of our esteemed customers was facing a
productivity challenge in their welding process and turned to our team for a solution.
Our experts suggested using SigmaWeld Induction Heating Solution, and the results
were impressive – a 100% increase in productivity.
The customer’s previous process involved setting up resistance heating coils around
the job, which took two hours. Achieving the required temperature of 205°C for
preheating with resistance heating took 2.5 hours, with a mains current of loading time
of 80-90 amps required. After welding, setting up coils for post-heat required another
two hours, and it took three hours to achieve the temperature of 350°C for post-heating.
The total time taken to complete one full cycle of pre and post-weld heat treatment was
9.5 hours.
Our experts suggested using SigmaWeld Induction Heating Solution, which uses the
concept of induction to generate heat directly inside the metal, resulting in quick and
easy heating without affecting the surroundings. With SigmaWeld, the flexible and
customizable blanket setup time is reduced to around 10 minutes. Achieving the
required preheating temperature of 205°C takes only 20 minutes, with a mains current
required for SigmaWeld induction heater to operate between 0-45 amps. Current input
required during Soaking/Holding time is as low as possible, 0-45 amps.
After welding, setting up the coil for post-heat takes only 10 minutes, and it takes only
40 minutes to achieve the temperature of 350°C for post-heating. The customer was
able to increase productivity by 100% simply by using SigmaWeld Induction Heater for
Pre-weld and Post-weld heating.
The key advantage of SigmaWeld Induction Heating Solution is that it eliminates the
need for resistance heating coils, resulting in faster and more efficient heating. In
addition, the SigmaWeld blanket is flexible and customizable, allowing for precise and
targeted heating of specific areas, resulting in reduced energy consumption and
increased cost savings.

The SigmaWeld Induction Heating Solution is an excellent example of how innovative
technologies can revolutionize traditional manufacturing processes, resulting in

increased productivity, reduced costs, and improved product quality. By adopting
cutting-edge technologies like induction heating, manufacturers can stay competitive
and stay ahead of the curve in today’s fast-paced manufacturing industry.
In conclusion, SigmaWeld Induction Heating Solution is a game-changer for the welding
industry, offering a more efficient and effective solution for pre-weld and post-weld
heating. By adopting this innovative technology, manufacturers can significantly
increase productivity, reduce costs, and improve product quality, making it a worthy
investment for any business looking to stay ahead of the curve in today’s highly
competitive manufacturing landscape.
