Our factory is now using ER50-6 wire gas shielded wire made from Shandong cable to do carbon dioxide and argon arc welding wire:1, using ER50-6 as carbon dioxide welding wire, the use of the condition is about 1.5 of the hot plate or cold plate, welding equipment shell, suitable?2, do argon arc welding wire with ER50-6, use condition is welding 0.8-1.5 of cold plate cylinder, after welding the cylinder still need to carry on two sides drawing and expanding, is ER50-6 suitable? Is there a more suitable welding wire to ensure that the expanding cylinder does not fuse? Please recommendThe second question is especially important. Please give your advice. StopThe mechanical properties of the ER50-6 were found to beTensile strength (b = 500MPa), yield strength (0.2 sigma) = 420MPa, elongation (5,%) = 22Deep drawing requirements, if the elongation is greater, the more suitable for welding wire?
The first problem is that ER50-6 is a solid welding wire. It is used in argon arc welding. How can CO2 be used to protect it? I don't think so!The second question, no one can guarantee you this safety problem, only you can see the performance of the parent material to choose.
If the material is matched and the operation is OK, the effect on the performance should be modest
ER50-6 is originally one of the most commonly used carbon dioxide welding wire, the elongation is great, of course, argon arc welding is not good, you change to ER55-B2 or ER55-B2-Mo will do.
Upstairs, man, the answer is incorrect.Absolutely. The chemical composition is the same.
