  In the use of cone crushers, wear parts often need to be replaced due to damage. Today we will introduce how to correctly replace the stone crusher parts name main frame seat liner.   Many customers report that the parts of crusher machine main frame seat liner is difficult to weld on the main frame. This is mainly because they do not master the welding process. Pay attention to the following points:   1. Thoroughly clean the welding position.   2. Heat the main frame to 100 degrees before welding, and the cone crusher parts name main frame seat liner also needs to be baked to about 40-50 degrees.   3. Weld from the middle to both sides.   4. Keep warm for 1 hour after welding.   In China, the welding rod we usually use is T237 3.2mm. The following are the main parameters of the welding rod.   Aluminum-manganese bronze is a copper alloy electrode with a welding core and a low-hydrogen coating. The deposited metal contains alloys such as Al 6.5-10%, Mn≤2.0%, Cu＜90%, etc., with excellent wear resistance and corrosion resistance. A DC power supply is used, and the electrode is connected to the positive electrode. It is used for welding aluminum bronze and other copper alloys, copper alloys and steel, and repairing cast iron. Such as welding of various chemical machinery, seawater radiators, valves, surfacing welding of water pumps, cylinders, etc. and repairing of ship propellers. Before welding, the electrode needs to be baked at about 200℃ for 1h. The moisture, oil, oxides and other impurities on the surface of the weldment must be cleaned. For welding aluminum bronze and surfacing welding of carbon steel, thin parts do not need to be preheated, and thick parts must be preheated at about 200℃.
