I know that stainless steel welding in low-temperature environments requires impact testing.

It is specified in 7.2.3 of GB1504-2011

According to ASME VIII-1, UHA-51(d) exempts wood and heat-affected zones from impact testing; for austenitic chromium-nickel stainless steels, this applies to materials such as 304/304L, 316/316L, 321, and 347, where the MDMT is above -196℃
