Precautions for use
- Preparation before welding: Clean the oil, rust and other impurities on the surface of the parent material thoroughly, select the appropriate welding wire and ensure it is dry, and check whether the welding equipment can operate normally.
- Welding process: Reasonably set the welding current, voltage and speed parameters, use high-purity shielding gas and control the flow rate, pay attention to the welding environment temperature not less than 5℃, humidity not higher than 80%, and maintain a stable operation method.
- Post-weld treatment: Clean the slag and spatter on the weld surface in time, perform appearance and non-destructive testing on the weld according to the standard, and perform post-weld heat treatment such as stress relief annealing as needed.
FAQ
What are the main alloying elements of ERNiCrMo-10?
+
-
The main alloying elements of ERNiCrMo-10 are nickel (Ni), chromium (Cr), molybdenum (Mo), and a small amount of iron (Fe), niobium (Nb), titanium (Ti) and other elements, which give it good corrosion resistance and high temperature performance
What are the requirements for welding grooves when welding ERNiCrMo-10?
+
-
The form and size of the welding groove should be determined according to the thickness of the weldment, the joint form and the welding process. Generally speaking, the groove angle is about 60°-70°, the blunt edge is 1-2mm, and the gap is 2-3mm to ensure that the root of the weld can be fully fused and reduce defects such as incomplete penetration.
Can ERNiCrMo-10 be used for welding of seawater desalination equipment?
+
-
Yes. ERNiCrMo-10 has excellent seawater corrosion resistance and can resist chloride ion corrosion in seawater. Therefore, it is very suitable for welding key components such as evaporators and condensers in seawater desalination equipment.
How to detect the quality of ERNiCrMo-10 welds?
+
-
Usually, visual inspection, non-destructive testing and mechanical property testing are used. Visual inspection mainly checks whether there are defects such as pores, cracks, and undercuts on the weld surface; non-destructive testing includes radiographic testing, ultrasonic testing, magnetic particle testing, etc., which are used to detect defects inside the weld; mechanical property testing includes tensile testing, bending testing, impact testing, etc., to evaluate whether the mechanical properties of the weld meet the requirements.
What should be paid attention to during the storage of ERNiCrMo-10 welding wire?
+
-
ERNiCrMo-10 welding wire should be stored in a dry and well-ventilated environment, the temperature should be kept between 5℃-35℃, and the relative humidity should not exceed 60%. The welding wire should be placed on the shelf, at least 300mm away from the ground and the wall to avoid moisture and rust, which will affect the welding quality.
