At Tempco, consistency is critical to delivering reliable heating solutions at scale. This year, the addition of laser welding technology to the production floor has strengthened that consistency across multiple heater product lines by standardizing weld quality, reducing variability, and streamlining setup from job to job.
Standardized Welding for Repeatable Results
One of the useful advantages of the laser welder, in addition to the increased speed of the actual welding, is the setup speed. The welder has the ability to store up to 100 programmable welding settings. Each program defines parameters such as wattage, wire feed speed, and other key variables based on material type and thickness. Once established, these settings can be recalled instantly for future jobs.
This approach removes much of the variation traditionally associated with manual welding adjustments. Whether an operator is working on stainless steel housings or mild steel brackets, the correct parameters are already dialed in. The result is consistent weld penetration, appearance, and strength across production runs and across operators.
“When you select the program, everything is already set,” said Manufacturing Engineer Jim, who led the implementation. “Once you get the feel for it, it’s literally as easy as pulling a trigger and going. That’s what makes it so consistent.”
Precision That Supports Fit and Assembly
Many Tempco heaters rely on thin-gauge steel components where dimensional accuracy is essential. Excessive heat from traditional welding can cause warping, leading to fit-up challenges during assembly.
The laser welder’s focused energy input minimizes heat distortion, helping parts remain flat and dimensionally accurate. This precision improves consistency not only at the welding stage, but throughout downstream assembly, reducing the need for rework or adjustment. An adjustable power allows operators to fine-tune the amount of heat applied, supporting the wide variety of heater configurations Tempco produces, from band heaters to larger duct heating systems.
Laser welding produces clean, uniform welds with minimal excess material. This consistency benefits finishing operations, especially for heater components that will be visible or coated. Optional features can also produce visually uniform weld beads or assist with surface preparation, further supporting a controlled, repeatable manufacturing process.
Consistency That Improves Throughput
By eliminating setup guesswork and reducing post-weld cleanup, the laser welder has delivered measurable time savings. Products like the MI-Plus Band Heaters now move through welding in roughly half the time compared to previous processes while maintaining consistent results from unit to unit.
“Everything we’ve tried has taken a quarter to half the time it used to,” Jim noted. These gains free up capacity on the production floor without adding labor or equipment footprint, allowing Tempco to respond more effectively to changing customer demands.
The technology has also proven versatile beyond product welding. Jim recently fabricated a pressure testing fixture for duct heaters entirely with the laser welder, demonstrating its value in maintaining consistency not only in products, but in tooling and production support as well.
Building a More Reliable Production Process
The introduction of laser welding technology represents more than a speed improvement. It reinforces Tempco’s ability to deliver the same level of quality, every time, across a growing range of heater products.
By standardizing welding parameters and reducing variability, Tempco strengthens the reliability of its manufacturing process from the first weld to final assembly. As production demands evolve, this consistency ensures Tempco can scale output while maintaining the craftsmanship and performance customers have trusted for decades.
