Overview
This document highlights the superior performance and quality of Tempilstik temperature indicators used in welding processes, particularly in challenging environments like the Trans-Alaska Pipeline.

Superior Quality Welds
- Tempilstiks exceed industry standards, being free of sulfur, lead, and halogen contaminants.
- Made from high-quality materials that enhance the welding process.

Increased Efficiency
- Tempilstiks are more durable and efficient than other temperature indicators.
- They provide faster results, reducing setup time and downtime.
- Reliable in extreme welding conditions with a slip-resistant aluminum holder for better control.

Temperature Accuracy
- Visual melt indicators provide results within +/- 1% of the rated temperature.
- Helps reduce crack formation, shrinkage stress, distortion, and hard zones near weld areas.
- Promotes hydrogen diffusion from steel.

Confidence and Compliance
- Secure supply chain and experienced distribution network.
- Prequalified to meet AWS D1.1, ASME Code Sec. I, III, and VIII, ANSI/ASME Code B31.1 and B31.3.
- Each Tempilstik is marked for traceability and is NIST traceable.
- Certifiable for nuclear use.

Applications
- Surface preheating, welding, and metal fabrication.
- Annealing, stress relieving, interpass monitoring, and controlling.
- Post-weld surface heating and machine operations.

Track Record
Tempilstiks have a 70-year history of measuring critical temperatures for WPS, WPQR, and WPQ requirements.
