How to Repair the Seams of the Jaw Crusher in the Welded Stander
How to repair the seams of the jaw crusher in the welded stander
The manufacture process of jaw crusher stander is complex, sometimes the welding will generate the welding seams during production, for the welding seams, how to deal with them?I will share the methods about how to repair the welding seams of the jaw crusher in the welded stander .
1.Keep the electrode dry and the weldment clean
Choose the electrode E 5017 which has the better crack resistance , the temperature in the drying box is 350-350 ℃.Two hours of drying, the dried electrodes are mounted into the preservation box for use at any time , rigorously clean the oil and impurities in the range of 50-100 mm near the weld groove before welding them and grind the electrodes until the metallic luster appears with hand wheels .
2.The dehydrogenation treatment of preheat and post weld .
Preheat the workplace to 150 ℃ before welding,After welding the workplace ,heat them to 300-400 ℃ for 1 hour ,then cover them with the asbestos to buffer them to room temperature.
3.The reasonable weld and welding sequence.
Adjust the weld and welding sequence ,turn the straight weld into the symmetrical, segmented, backward and multi-layer narrow pass weld, by adjusting the welding sequence to prevent deformation ,and reduce the welding stress , besides the cover layer and physical layer, after each layer of welding road is welded, the stress must be eliminated by hammer beat .
