How to repair the stitches of the chin crusher inside the welded stander The production process of jaw crusher stander is sophisticated, sometimes the welding can generate the welding stitches during development, for the welding seams, how to deal with them? I will share the methods about how precisely to repair the welding stitches of the mouth crusher in the welded stander.
1 . Keep the electrode dry and the weldment clean
Choose the electrode Elizabeth 5017 which includes the better crack resistance, the temperature in the drying out box is usually 350-350 в„ѓ. Two hours of drying, the dried out electrodes are mounted in to the preservation field for use anytime, rigorously brush your oil and impurities in the range of 50-100 mm close to the weld groove before welding them and grind the electrodes until the metallic original appeal appears with hand rims.
2 . The dehydrogenation remedying of preheat and post welds.
Preheat the workplace to a hundred and fifty в„ѓ ahead of welding, Following welding the workplace, heat those to 300-400 в„ѓ for 1 hour, then cover them with the asbestos to buffer these to room temp.
3. The reasonable welds and welding sequence.
Adjust the weld and welded sequence, turn the straight weld into the symmetrical, segmented, in reverse and multi-layer narrow move weld, by simply adjusting the welding collection to prevent deformation, and reduce the welding stress, besides the cover layer and physical level, after each layer of welding street is welded, the stress should be eliminated by simply hammer defeat.
