Then, the groove at the lower end of the upper box column and the head of the lower box column are welded. During this welding, a slit is formed around the entire circumference between the tip of the groove and the head, so the heat generated by welding passes through the slit and reaches the inside of the box column, resulting in a good preheating effect. At the same time, airflow does not pass through the slit without convection and welding defects such as blowholes do not occur.
Good welding can be obtained.
