For example, titanium alloy welding can quickly absorb hydrogen when the temperature is above 300°C, quickly absorb oxygen when it is above 450°C, and quickly absorb nitrogen when it is above 600°C, so the titanium alloy weld is solidified and the temperature drops to 300°C All of the following stages need to be effectively protected, otherwise they will be 'oxidized'.
