【Haichuan Pipeline Construction】Have you ever seen air holes inside pipeline welds?

Thread Content

I saw online shared images of defects such as pores after inspection, along with pictures taken by workers who carried out grinding

Is this pore so large because the welding was done too quickly and the hydrogen didn’t escape?

Besides hydrogen pores, there are also carbon dioxide pores and so on; it seems nothing has leaked out
