[0002] A filter is a component of a compressor drying equipment. During the manufacturing process of the filter housing, it is necessary to install a filter element joint inside the filter housing, connect an air inlet pipe joint to the filter element joint, and then weld the contact part between the air inlet pipe joint and the filter housing, and fix the air inlet pipeline on the filter housing.

[0003] Since the filter element joint is made of stainless steel, it is prone to heat-induced deformation during the welding process, resulting in the skew of the filter element joint, which causes the displacement of the air inlet pipe joint during the welding process, affecting the welding effect of the contact part between the air inlet pipe joint and the filter housing, and even leading to rework or scrapping of the entire filter housing.
