Ernicrmo-3 Filler Wire
Product name: ERNiCrMo-3 filler wire, also known as ERNiCrMo-3
Origin: Hangzhou, Zhejiang, China
Product summary
ERNiCrMo-3 filler wire, also known as ENiCrMo-3, is manufactured to strict compliance with AWS A5.14, ASME II SFA-5.14 standards. As a professional manufacturer, we rely on advanced production technology and strict quality control to ensure that every welding wire has excellent reliability and stability.
Product Advantages
Excellent corrosion resistance
Filler wire can effectively resist the erosion of various strong corrosive media such as acid, alkali, salt, seawater, etc., and significantly reduce the risk of pitting, crevice corrosion and stress corrosion cracking.
Good oxidation resistance
In high temperature environment, Filler wire can quickly form a dense and stable oxide film, effectively inhibit the continuous oxidation reaction, and ensure that the material can still maintain excellent performance under high temperature conditions.
High strength and excellent mechanical properties
With high tensile strength and excellent fatigue resistance, it can stably maintain good mechanical properties in a very wide temperature range. Filler wire can easily cope with the test of heavy loads and cyclic loads.
Excellent weldability
It is suitable for a variety of mainstream welding processes such as manual arc welding, argon arc welding, submerged arc welding, gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), etc. No matter what welding position it is in, it can achieve stable operation, the arc is stable during welding, the weld is beautiful and the quality is reliable.
Welding process control
- Taking the GMAW welding process of 1.2mm diameter welding wire as an example, it is recommended to set the voltage at 26-29V, control the current at 150-190A, select 100% pure argon as the shielding gas, and use direct current reverse connection (DC-). This is because:
- Cleaning the oxide film on the surface of the weldment: When the filler wire is in DC-, the weldment is connected to the negative electrode and the welding wire is connected to the positive electrode. Electrons flow from the welding wire to the weldment, and positive ions move from the weldment to the welding wire. When the positive ions hit the surface of the weldment at high speed, they have greater energy and can effectively break and remove the oxide film on the surface of the weldment, especially the refractory oxide film on the surface of the nickel-based alloy, providing a clean welding surface for subsequent welding and improving the quality of the weld.
- Improve penetration: When DC is reverse connected, the arc heat is mainly concentrated on the weldment, causing the weldment to gain more heat, thereby increasing the penetration of the weld, which is beneficial to ensuring the strength and reliability of the welded joint and meeting the penetration requirements of filler wire welding.
- Stable arc: Under DC reverse connection, the ERNiCrMo-3 filler wire arc has better stability and more uniform arc burning, which can reduce spatter and arc blow during the welding process, ensure the smooth progress of the welding process, and help obtain beautiful, high-quality weld formation.During the welding process, a stable and appropriate welding speed and arc length need to be maintained.
2. During the welding process, it is necessary to maintain a stable and appropriate welding speed and arc length.
3. When performing multi-layer and multi-pass welding, strictly control the interlayer temperature to prevent the degradation of weld performance due to overheating, and avoid welding defects such as undercut, pores, and cracks.
