I need to make a repair weld on a clutch plate made from "spring steel". This is all the information I have on the material without doing a chemical analysis. There are several cracks that need to be repaired and an area that needs to be reinforced. I am leaning towards using a 309L...
I am in the process of starting a Consulting business pertaining to Welding Engineering, Inspection and QA.
I have a BS degree and about 20 years of very good experience. However I'm not sure how to charge my customers. Any guidelines or fee ranges would be very helpful.
I would like to know if anyone has information on CVN Impact Values (ft lbs @ 0 deg. F) from the following:
Base material 1/2" SA-387 Gr. 11 Cl. 2 (ASME P4)
FCAW process using 1/16" dia. E81T1-B2 Filler & 100% C02
Preheat @ 300 deg. F maintained through completion of weld.
Slow cool...
I am gearing up to weld SA-387 Gr. 91 material. I will be qualifing procedures in accordance with ASME Sec. IX using SMAW, SAW, FCAW and GTAW. I have been in contact with Euroweld, NC concerning proper methods (i.e. consumables, preheat, post-weld soak and PWHT). However any additional...
