验收标准：焊区整个外表面进行萤光磁粉探伤，检验是否有横向缺陷，横向缺陷经打磨后仍然无法完全去除，视为不合格品，
当横向缺陷经打磨以完全去除并光滑过渡，且打磨后尺寸符合图纸要求, 视为合格品。

Acceptance criteria:
To do the fluorescent magnetic particles test for the surface of welding zone and check whether there are horizontal cracks. If there are cracks and the cracks cannot be removed after grinding, these products will be rejected. If the cracks can be removed completely and transit smoothly after grinding, also the grinding size is according to order drawing strictly. These products are accepted.
