| 1. IF elbow with vertical external characteristics of the power supply, DC with positive polarity (wire then negative) 2. IF elbow is generally suitable for 6mm below the thin plate welding, with weld appearance, welding deformation of small features 3. The shielding gas is argon and has a purity of 99.99%. When the welding current is 50 ~ 50A, the argon flow rate is 8 ~ 0L / min, when the current is 50 ~ 250A, the argon flow rate is 2 ~ 5L / min.??????? ?? ??????????? ????? ????? 304 ? ?????? ??? 4. Welding arc length, welding ordinary steel, to 2 ~ 4mm is better, and welding stainless steel, to ~ 3mm is better, too long to protect the effect is not good. 5. IF bend to prevent the emergence of welding holes, welding parts such as rust, oil, etc. must be clean. 6. The length of the tungsten protruding from the gas nozzle is preferably 4 to 5 mm, preferably 2 to 3 mm in the case of poor weldability such as fillet welding, 5 to 6 mm in the slotted area, and the distance from the nozzle to the working More than 5mm.Sus431 Hot Rolled Stainless Steel Sheet 7. IF bending pipe docking primer, in order to prevent the back of the bottom of the weld was oxidized, the back also need to implement gas protection. 8. Wind and ventilation. There is a windy place, please take measures to block the network, and in the room should take appropriate ventilation measures. 9. IF Bend In order to protect the welding pool well and to facilitate the welding operation, the tungsten center line and the welding part of the workpiece should generally maintain 80 ~ 85 ?? angle, fill the wire and the workpiece surface angle should be as much as possible To small, generally about 0 ??.2b ba acabado astm 304l tira de acero inoxidable 304 high-pressure pipe is mainly used for heating straight seam pipe, seamless steel pipe, through the IF heating, to achieve the effect in order to produce. IF induction heating elbow is an advanced bend method. However, if the elbow process is not appropriate, there may be loose metal pipe damage phenomenon. This damage is manifested as a fine grain boundary crack, the mechanical properties of the pipe and the service life have some adverse effects.Vástago de acero inoxidable 409 de suministro de China |
