4 Notes on usage General information nce Flux cored wire is softer than solid MIG wire, do not excessively tighten the pressure roller in wire feeder. At flat butt welding, back-step process makes penetration stable. At horizontal position and over head position, straight sequence is good for getting flat bead appearance. At horizontal fillet welding to primer-coating plate, blowhole defects such as pit, gas hole are apt to occure easily. Therefore, appropriate selection of wire and parameter setting for welding primer-coating plates are necessary. When welding is done in excessive heat input and excessive welding currents, there are possibility to lower mechanical properties of a weld metal. As cold cracks are caused by diffusible hydrogen, In general, it is necessary to remove it by selecting proper preheat and interpass temperature depending upon welding process. Normally as tensile strength becomes higher It is better to apply higher preheat and interpass temperature. When heat input is excessive, the impact value tends to be reduced. Therefore, perform welding with selecting proper heat input according to the required impact value. nce rust, oil and dirt are apt to make welding defects such as pit, blowhole, lease remove them from the groove by grinder for instance before welding. In order to minimize cracking of hardsurfacing, the followings must be taken into account : reparation of base metal Heat and temperature control enetration Welding distortion Underlaying Welding power source Use a D power source with constant voltage and the polarity D-E except several self shielded items. Use for shielding gas for general applications. Ar+ mixtures with 20~50% can also be used, but compared with, porosity(pit and blowhole) is apt to occur. in welding with an Ar+ mixture should be 5mm longer than in use of Wire extension Keep the wire extension at about 15mm for 0.9mm wire and 15~20mm for 1.2mm and 1.6mm wire. The use of a shorter wire extension may cause pit and wormhole. The wire extension in welding with an Ar+ mixture should be 5mm longer than in use of 185

5 Notes on usage rotection against wind When wind velocity at the vicinity of an arc is more than 1m/sec. Blowhole is apt to occur and dissolution of nitrogen into the weld metal may deteriorate slag removal and decrease the ferrite content of the weld metal in case of stainless flux cored wire, thereby causing hot cracking. To prevent these problems. use an adequate shielding gas flow rate and a windscreen. Welding fumes Flux cored wires generate much more welding fumes in terms of the amount of fumes at unit time in comparison with that of covered electrodes. To protect welders from harmful welding fumes, be sure to use a local ventilator and an appropriate respirator. torage of wire Once Flux cored wire picked up moisture, it cannot be dried at high temperature, unlike covered electrode. If a wire was left in a wire feeder in a high-temperature high-humidity atmosphere in summer season, a wet environment in rainy season or a dewfall environment at night in winter was unpacked, the wire should be kept in an area of low humidty. Temp. below 30 relative humidity below 60% 186
