Can Q345E and Q345B be soldered together? What flux and wire are used?
If there is no specific performance requirements, just want to connect them together, then using manual electrode welding, selection of basic electrode J507 or acid electrode J422 is ok.
Sure。 With H10Mn2 wire and flux SJ101
Yes, these two materials are of an intensity grade. But the ingredients are different from the S and P impuritiesIf you use carbon dioxide gas protection, choose the wire for: ER50-6 (this is the national standard), with carbon dioxide gas or 80% argon +20% carbon dioxide;If the use of submerged arc welding wire H10Mn2+ flux: HJ431 or H10Mn2SiA + - SJ101. before a combined welding process better, forming slag removal are better, but as a combination of mechanical properties after, but after a combined welding process slightly worse than the former one but the mechanical properties are a good mechanical properties, including the main difference is the low temperature impact toughness, after a is better than the former.
