Selection and development of guidelines for solderability test methods: Selection and development of guidelines for solderability test methods: Comparability: Conditions for solderability tests should be as close as practical to the conditions of soldering. Specificity: Solderability tests should be aimed at detailed soldering Structural reproducibility: The results of the welding experiment should be stable and reliable, with good reproducibility economy: Think about the cost of the third chapter of alloy structural steel welding This chapter needs to grasp the concept: Self-tempering: M transition point higher low carbon Alloy steel, in the quenching process, first constitutes a low carbon M. Due to the higher temperature, in the process of other M self-tempering changes from time to time, due to the workpiece's own temperature, it loses temper and eliminates the stress, so it is not required. Special tempering process, this phenomenon is called "self-tempered." Conditioning treatment: The heat treatment process of quenching and tempering is called quenching and tempering.

Previous: Melt ratio and cooling rate Next: The principle of the plug test is used to measure the cold crack sensitivity of the low alloy steel heat affected zone
