4.4. Example of Multipass Welding

4.4. Example of Multipass Welding

 

The work program can be written as below.

This work is about performing welding in a way that after the 1st pass welding is completed, the 2nd pass welding and 3rd pass welding are performed while being shifted 3.0 mm to the left and right at an elevated height of 3.0 mm.
