Forging tools, types of mandrels, high-temperature cutting tools and coating of unalloyed or low-alloyed metals.
The welding surface should be well cleaned and free from any cracks and contamination. Preheating should be used at approximately 400°C and the temperature of the part should be maintained within this range during welding. If necessary, stress relief should be performed at 550°C.
