Installing and repairing hinge rivets can be difficult with a torch. Flooding a hinge with solder and permanently joining a link to adjacent links are among the risks when using a torch and solder.
Use of the following pulse-arc welding techniques to weld the hinge rivets will eliminate potential problems and speed up the overall procedure.
Tack-, fusion- and pulse-arc equipment settings will differ and are based upon the volume, amount of contact and alloy of the material you are working with. Practicing using like materials will give you a parameter for the settings required for your application. Keep a record of settings and tasks for future reference.
