That depends on where the weld is, but still it does look below standard in today's day and age and for a DDG that is simply not acceptable, you do not want these kinds of welds in a ocean going warship, in war that could make all the deference, no matter how good your damage control sailors are
But then this isn't today's warship, it was built over a decade ago when it was most likely a "first" attempt, the pace at which Chinese warship design and construction has advanced is almost unbelievable and a look at a Type 054A and Type 052C will prove it
Nevertheless the other pictures show a good standard of maintainence, everything is squared away organised and it looks they are following a standard operating procedure by the way it is presented, most things have a fixed place and they are safely installed
Modern Chinese welding and machinery technology is on par with the best warship designs, For Azmat Class the technology's were all imported for the 2nd ship and installed at Karachi dockyard who also have French technology for construction of Agosta Class SSK, same for JF17 the precision technology machine tools were imported for the construction for the aircraft, all of them pretty good
Sometimes you wonder how well the PLAN sailors are under war like conditions, for example, how would they react when there is a explosion on board, how is the body language, how do the people responsible take charge, how does the captain lead from the front, what effect does the explosion have on injured sailors and moral, how quickly do they get the scene under control, do they show valour and risk of life to save the ship, this is what wins battles this is what it takes to save a ship and recover it
Not that anyone wants a explosion on board but some times you can't help but think about what are very real issues for sailors at sea
