How to weld 20 tubes together with Cr5Mo elbows without affecting strength

Reply #22008-02-21

For thicknesses of 8mm and below, the welding materials H10MnSi+J427 can be used; preheating at 250°C is required, followed by heat treatment at 680±10℃ for 0.5 hours. The evaluation standards are JB4708. This post was last edited by ssmith2007 on 2008-2-21 at 20:59

When welding 20 tubes to Cr5Mo elbows, it is necessary to first use TIG welding for the root pass, followed by MIG welding; a weld rod of a higher grade should be used, such as I307, so that the welding does not affect the strength of the steel.
