E312-16 Welding Rod
Type: stainless steel welding rod
Brand: Ocean Welding
E312-16 welding rod Product Features
Excellent crack resistance:
Since the deposited metal contains about 40% ferrite, the weld metal has good crack resistance and can effectively prevent the occurrence of cracks during welding.
Excellent welding process performance:
Titanate red coating design, AC and DC dual-use, the electrode is resistant to redness, the arc is soft, the spatter is smaller, the operability is good, the all-position weldability is good, and the welding process performance is excellent.
Wide applicability:
Mainly used for welding high carbon steel, tool steel, high temperature steel, armor steel and dissimilar metals, such as Cr29Ni9 cast steel, duplex stainless steel, etc.
Wide range of applications
Reactor: Using welding rod for welding, with its excellent crack resistance and corrosion resistance, can ensure the stability of the weld and effectively prevent leakage hazards.
Pipeline system: Due to its wide applicability, welding rod can achieve reliable welding of dissimilar metal pipes such as high carbon steel and stainless steel, ensuring that the pipeline system has good sealing and strength, and maintaining the stable operation of the device.
Mechanical manufacturing industry: In mold manufacturing and repair work, when splicing and repairing molds made of high hardness and high carbon steel, welding rod can ensure the strength of the weld, while reducing the impact on the performance of the mold material, thereby extending the service life of the mold. welding rod is also used in the manufacturing and repair of large gears. This welding rod can be used for welding of gear teeth, hubs and other parts, especially for gears connected to parts of different materials, which can ensure the transmission accuracy and mechanical properties of the gears.

E312-16 welding rod Packaging
We use strict and scientific packaging methods, usually 5kg/plastic bag + inner box, 4 inner boxes (20kg)/carton, 1 ton/pallet. Plastic bags are effective in moisture-proofing, inner boxes provide buffering protection, and cartons are easy to carry and store, ensuring that the product is not damaged during storage. In addition, we can also customize special packaging solutions according to customer's personalized needs.
Instructions for use
- Before using the electrode, be sure to bake it at about 250°C for 1 hour. This key step can effectively remove moisture from the coating, avoid defects such as pores and cracks caused by moisture during welding, and ensure that the welding quality reaches the best state.
- During welding operations, it is recommended to use a DC power supply to obtain a more stable arc and better welding effect. At the same time, the welding current must be strictly controlled and should not be too large. Excessive current may cause the electrode to overheat and the coating to fall off, affecting the welding process performance and weld quality.
- During the welding operation, maintain an appropriate and uniform welding speed and control the arc length. The appropriate welding speed can ensure that the weld metal is fully filled and fused, and the appropriate arc length can maintain arc stability and reduce spatter, ultimately ensuring that the weld is well formed and has excellent appearance and internal quality.
FAQ
Q: What is E312 16 welding rod used for?
A: The E312-16 electrode is a multi-purpose electrode used primarily for dissimilar metal welding, high sulfur steel welding, and certain weld overlay applications.
Q: What should I do if porosity appears in the weld when using E312 16 welding rod?
A: The welding rod may be damp, so make sure it is dry and dry it if necessary. It may also be that there are impurities such as oil, rust, etc. on the surface of the weldment, which need to be thoroughly cleaned before welding.
