Hi, If this is a low voltage iron you are better off crimping the wires rather than soldering them, sometimes the wire used will not solder succesfully. Idealy you need two short lengths of heat proof sleeving to slide over your connections to prevent shorting. If this iron is mains powered then you need to take extra precautions regarding safety issues!  Lastly you can make crimps from short lengths of hollow metal tube. Select the diameter so you can pass the heating wire through one end and the power wire from the other. Squeeze with pliars to secure, don't forget to slide your insulating material over the joint before crimping!
have fun... Regards

thank you man,that very help

It sounds like you're buying cheap soldering irons or doing something wrong with them? If the joints were soldered originally, then you should be able to fix them. If they weren't soldered you probably won't succeed.
You might be best investing in a good iron that won't break so easily.
