WELDING DEVICE OF MUFFLER AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A muffler welding apparatus and a muffler manufacturing method using the same are provided to manufacture various types of mufflers by aligning one end of a sub muffler coupled with a catalyst converter. CONSTITUTION: A muffler welding apparatus comprises a supporting unit(300), first and second welding units(100,200), an aligning unit(400), and first and second jig tools(500,510). The supporting unit supports a sub muffler(30) from bottom and lifts the sub muffler. The first welding unit welds a junction part between the sub muffler and a catalyst converter(20). The second welding unit welds a junction part between the sub muffler and a flange(10). After the sub muffler is set on the supporting unit, the aligning unit presses one end of the sub muffler to the second welding unit before coupling of the catalyst converter. A junction part between the sub muffler and the catalyst converter is located on the same line as the first welding unit, and the sub muffler and the flange are located on the same line as the second welding unit. The first and second jig tools are coupled to an end of the catalyst converter and an end of the flange, respectively to hold and rotate the catalyst converter and the sub muffler.
