The spot welding at the pipe end has penetrated – how should this be dealt with?

Repair or rework strictly in accordance with the welding procedures, based on the equipment requirements and materials

Carefully repair the weld using TIG welding, and then grind the inner side

This welder definitely hasn’t received any training; change the welder first, and then the pipe!

Are there any issues with the welding parameters?

Fill it in first, then grind it off with an electric grinder. This situation is encountered quite often.

The tube needs to be replaced. The welding heat input is probably too high. Why weld first? Also, looking at the picture, it seems that the length of the heat exchange tubes extending beyond the tube sheet is too large; shouldn’t it be shortened?
