A106 Gr.B may be welded?

Hi Everybody.
Can you help me for this issue.
According to ASME II SA106 Gr.B is normal seamless pipe. However can they be welded pipe?

SA 106 cover seamless pipe only.
If you would like to form a pipe by welding, should be refer to API 5L.
CE equivalent and mechanical properties may equal to PSL 1 grade L245 or X42.
