When welding nickel alloys, sulphur exerts a more pronounced effect on the weld metal than in other alloy materials. The primary concern arising from this influence is the issue of crystallisation cracks in the weld metal.
Summary
Selecting nickel alloy welding materials is a systematic process that requires:
1. Identifying the base material: Determine the specific grade of the base material to be welded.
2. Understanding the operating conditions: Understand the environmental conditions(temperature, corrosive media) and stress conditions of the joint.
Due to the weldability characteristics of nickel and nickel alloys, the selection of welding processes is crucial for ensuring successful welding of nickel and nickel alloys. Production practice has demonstrated that various methods are available for welding these materials,depending on production conditions and structural performance requirements. These methods include: arc welding, submerged arc welding,TIG,MG, diffusion welding,resistance spot welding, seam welding, and butt welding. Plasma arc welding, electron beam welding, and brazing are also possible. However, tungsten inert gas (TIG) welding and arc welding are more commonly used in production.
During welding, weld metal in nickel and nickel-based corrosion-resistant alloys, as well as nickel-based high-temperature alloys, exhibits significant susceptibility to crystallisation cracking. This is primarily associated with the following factors.

Important Tip: How to Confirm the Material You Need
There are significant differences between “Ni-Cr-Fe” and “Ni-Fe-Cr.” To ensure you’re selecting the correct material, we recommend the following steps:
1. Verify the Original Technical Documents: Carefully review your original documents, such as drawings, specifications,or purchase instructions. Verify the complete standard number (e.g., the full AWS A5.14 standard) and the base material to be welded (e.g., INCOLOY 825 or INCONEL600).This is the most critical step.
