Why is it important to follow a welding procedure using short welds on opposite sides of the cylinder?

Following a welding procedure that employs short welds on opposite sides of the cylinder is crucial primarily to prevent warping of the cylinder. When welding, the heat generated can create thermal expansion in the material, which, if not controlled, leads to warping or distortion of the cylinder. By applying shorter welds on opposite sides, the heat from each weld can be balanced out, allowing the material to cool down in a more controlled manner. This strategic approach helps to minimize the buildup of stress and reduces the likelihood of permanent deformation in the welded structure.

This technique is particularly important in applications where precision and structural integrity are critical, such as in lift systems where cylinders must maintain specific tolerances to ensure safe and reliable operation.
