Welding welding and the Welding Electrode of the metal structure of the alloy components of precautions in the work, it requires that the welded joint portion can withstand external forces without breaking. Welding with butt and mating welding, can also be used to drill welding, slot milling, welding, butt welding, lap welding. The solder alloy surface oxidation, rust or other dirt to clean up with emery cloth welding part of the metal substrate exposed. Temperature to be controlled, to avoid slag, porosity, and weld through and other phenomena. Replace more of the alloy components after welding to measure the cold resistance and three-phase current balance of the entire stove, make the appropriate adjustments to meet the original design requirements. Repair of nickel-chromium alloy, the first break in order to understand the component oxide. Oxidation serious, the silver core is thin and easily blown when welding, even if we manage to welding, but also not last long; oxidation is not too serious, the available lap France; such as the still relatively new, the available docking method. Usually used for gas welding nickel-chromium resistance wire for the wire. Docking method to use a neutral flame, the flame volume is small, the flame core should be straight, the heat should be concentrated; length of lap by lap welding method, the resistance wire is not less than 10 times the diameter; resistance with bandwidth of one times. Between the nickel-chromium alloy components and leads to stick welding lap welding or butt welding. Heated iron chromium aluminum alloy is not allowed in cold bending, stretching or excessive vibration, For plastic or expand the pitch must be heated to a dark cherry red. Electric arc welding, welding rod with the rare earth iron-chromium-aluminum electrode, the mating welding and intermittent welding, to control the heat range and overheat extent. Available slotting welding, drilling Welding Wire and slotting cold welding method. Generally between the iron chromium aluminum alloy components and leads to stick with drilling welding. If a layer of furnace wire resting on brick middle there will be a two fracture, with or without insulation, with a straight resistance wire, across the fracture or non-insulated furnace wire resting on brick, direct welding, will cause the furnace wire resistance, work from the outside, on the other furnace silk red, life is shorter.
