Adequate Supply 55nicrmov7 Alloy Material Welding Process Guide - China

• Thoroughly clean the oil, rust, impurities, etc.

on the surface of 55NiCrMoV7 alloy material.

Grinding with a grinding wheel, wiping with acetone, etc.

can be used to ensure that the welding area is clean, which helps to improve the welding quality and prevent welding defects.

• Preheating is necessary because the heat-affected zone of 55NiCrMoV7 alloy material may have problems such as hardening during welding.

The preheating temperature is usually between 200-300°C.

Overall preheating or local preheating can be used to ensure that the welding area and its vicinity reach the specified preheating temperature and are heated evenly.

• Special welding rods that match 55NiCrMoV7 alloy material should be selected.

For example, nickel-based alloy welding rods or welding rods with similar alloy components (nickel, chromium, molybdenum, vanadium, etc.

).

The diameter of the welding rod is selected according to the thickness of the weldment and the welding process requirements.

Common ones are 3.2mm, 4.0mm, etc.
