Recommendations for Welding T-1 Steels | WELDING

Please note that highly restrained joints may require higher preheat. Also, preheat should NOT exceed 400F for thickness up to 1-1/2 or 450F for thickness over 1-1/2. Because this is a Q&T steel we also have to abide by maximum preheat and interpass temperatures and not just minimums.
