According to specific factors such as the thickness of the weldment and the welding position, accurately adjust the welding current and voltage. Generally speaking, for nickel electrodes with a diameter of 2.5mm, the welding current should be controlled at 60-90A; for those with a diameter of 3.2mm, the welding current is 90-120A; for those with a diameter of 4.0mm, the welding current is 120-160A.
- Welding operation: It is recommended to use DC reverse connection welding. During the welding process, maintain a suitable and stable arc length and control the welding speed to ensure that the weld is beautiful and of good quality. When performing full-position welding, it is necessary to flexibly adjust the welding angle and technique according to different welding positions to achieve the best welding effect.
FAQ
Q: What materials can be welded with welding rod ENiCrFe - 3?
A: Nickel electrode ENiCrFe - 3 has a wide range of applicability and can be used to weld nickel-chromium-iron alloys, such as common nickel-based alloy materials such as Inconel 600, 601, and 690. At the same time, it can also excellently complete the welding tasks between nickel-chromium-iron alloys and dissimilar metals such as carbon steel and stainless steel.
Q: Why do welding rods need to be baked before use?
A: The electrode coating may absorb a certain amount of moisture during storage. If it is used directly without baking, the moisture will evaporate during welding, which may cause defects such as pores and cracks in the weld, seriously affecting the welding quality. Removing moisture by baking can ensure a smooth welding process and improve welding quality.
Q: What should I do if pores appear during welding?
A: Porosity during welding may be caused by damp nickel electrode, incomplete cleaning of weld surface, or unreasonable welding parameter settings. At this time, the nickel electrode should be re-baked in time, the weld surface should be carefully cleaned again, and the welding parameters should be checked and adjusted until the porosity problem is solved.
Q: What are the storage conditions for this welding rod?
A: Nickel welding rod ENiCrFe-3 should be stored in a dry, well-ventilated environment to avoid moisture. The relative humidity of the storage environment should be controlled below 60% and the temperature should be kept between 5-35℃. If the welding rod is found to be damp, it must be re-baked before use.
