Elbow making
According to the elbow’s angle and quantity of welding parts, the welding angle between every part can be decided.
Explanation: α － welding angle
β － elbow angle
n － quantity of segments
For example: 90°elbow is divided into five segments to be welded, the welding angle α=β/（n-1）=90°/（5-1）=22.5°
The min dimension of every welding part in the welding parts quantities is cut by the band saw according to the angle.
The elbow can be welded section by section as below:
