AMS 2750 - Pyrometry Dip Braze

Pyrometry Dip Braze

Present valid dip braze specs are AMS 2673, AWS C3.7 and various customer specifications. With the exception of AMS 2673, your braze requirements probably must be supported by calibration and certification to the requirements of AMS 2750 oven pyrometry.

In essence, pyrometry is all the requirements that heat treat ovens (dip braze is considered a heat treat process by Nadcap), pre-heat ovens, salt baths and heat treat ovens must meet.

Some of the things that Hi-Temp does to meet AMS 2750 requirements are:

1. All brazing furnaces meet +/- 5 degrees F system accuracy (determined by periodic calibration)
2. All pre-heat ovens meet +/- 25 degrees F uniformity: heat treat ovens meet +/- 10 degrees F (determined by periodic calibration)
3. All equipment is monitored by installing and periodically calibrating thermocouples at the coldest point, hottest point and the control point
4. All instruments are periodically calibrated and calibrated prior to installation
5. Data logging equipment is utilized to record all thermal processing
6. Records are maintained for 10 to years of the thermal processing of all government and mil spec parts.
