South Korea linked the anchor bolts are upright, using size cards to the test. Note the welding points break these not welded on steel bearing holder, only welded on steel structure's belt & BTCT must make sure sure.

Weld on the stem bolts only, no drag for welding carbon dots will reduce the intensity of bolts & cause brittleness phenomena
