What is InfraGuide?
InfraGuide is a unique infrared (IR) welding technology that addresses common issues like uneven heating and flare-ups. It utilizes small, 100 W bulb-type emitters to focus IR energy on the weld joints, with each bulb independently adjusted for uniform energy distribution. The technology also employs positive air pressure to clear off-gassing from the weld area, eliminating fire risks. This results in a safe, efficient, and clean welding process.
Joint Design
General Guidance:
- Include 1.00-1.50 mm (0.04”-0.06”) of material overlap in your weld joint.
- Build in 5.20 mm (0.21”) of clearance from nearby part features for module fitment. The specified clearance includes the following criteria:
- 1.30 mm (0.05”) offset from outer edge of the weld rib
- 3.18 mm (0.13”) for the module wall thickness
- 0.76 mm (0.03”) clearance from the module exterior to nearby part geometry to avoid interference
- If an internal feature protrudes past the weld plane additional clearance from the weld path will be required.
- If concealing flash is required, make the flash trap large enough to contain half the material displaced in the weld rib.
- Weld rib must be a minimum of 1.65 mm (0.06”) wide.
- Weld rib width is driven by assembly strength criteria.
Weld Path
Notes:
- Build in a minimum of 31.75 mm (1.25”) between close weld paths.
- Tolerance must be tight to ensure that the weld rib will be in line with the focal point of the module.
