Answer:

Or from the process of the performance of the weld is again high, the performance of HAZ is insufficient, still no comprehensive consideration.
This welding experiment has been done with Baosteel profiles. Mainly control the welding parameters, welding materials using ER120S-G. If you have any questions, you can talk about it privately. QQ397308237
