What are you going to do?Originally posted by right handed View Post
AR 400 armor-plate is generally welded with a low-hydrogen electrode, pre-heat, post-heat, peening,and carefully controlled inter-pass temperature, to maintain abrasion resistance and hardness.
If you are repairing mining or construction equipment, you will need the proper flux-cored or metal cored wire, as well. Gas may be different or may not be required.
Welding instructions are often available from steel suppliers or machinery manufacturers. If you are using it for non-critical purposes, where failure consequences are minor, some of the above may not be as important.Last edited by Northweldor; 02-02-2016, 04:17 PM.
