Can Q245R and Q345R be welded together?
Thread Content
For a DN600 manhole flange, the barrel section is made of Q345R, while the flange is a plate-type butt-welded flange fabricated from Q245R. The design pressure is 10 kilograms – can these two materials be welded together for use? Of course, this manhole is non-standard
That’s great; not only can such carbon steels and low-alloy steels be welded together, but carbon steels can also be welded with heat-resistant steels, stainless steels, and so on.
Well, how should I put it? It’s definitely very good
It can be welded using J427 welding rods

Welding is possible; low-carbon steel Q245R and low-alloy steel Q345R have good weldability. Choose welding materials J426 or J427 based on the lower strength level
I think it’s really inappropriate to ignore such common sense:victory:
No problem at all; it can be welded
Yes, this kind of situation occurs frequently on devices
