Welding technique is of fundamental importance and it is presupposed that welding procedure and inspection shall be in accordance with approved methods for the class wstm material used. Brinell Hardness testing is required 7.

ASTM A291 Grade 5

Brinell hardness tests shall be made on prepared areas on the forgings after machining to the sizes ordered by the purchaser and after stress relieving if stress relieving is required. So, first design asym small diameter Atsm, Gears and Shafts per A, then choose a matching alloy in Table 1 of A for the large diameter ring gear.
