Why is the lower thickness limited for Impact Tested Welding Procedures?
Why is the lower thickness limited for Impact Tested Welding Procedures?
(OP)
Hi! Time and again I stuck to the question that: Why is the lower thickness limited for Impact Tested Welding Procedures?. Where as Metallurgically, increasing the thickness usually increases the chances of retained austenite/martensite, thereby decreasing fracture toughness/impact strength.
Thanks in advance.

Primary cooling during welding is through conduction (metals have high heat conductivity) and not through convection. The greater the heat sink (mass/volume) the faster the cooling rate.
