Welding issues related to C12A
Thread Content
Question: What type of welding rod or wire should be used for welding C12A to grade 3 forged steel, and what are the required welding conditions?
I checked it – C12A is a US standard grade; the equivalent forged material grade is F91. Cracks tend to occur after welding. If you plan to weld it with grade 20# steel forgings, you might want to try using J507 welding rod as a substitute. This is just for reference.
Thank you, moderator. After waiting for so many days, you are the only one who has responded. It seems that there aren’t many people with experience in this area of welding; therefore, I hope even more that experienced experts will share their knowledge so that we can all learn, discuss, and improve our skills.
