There are obvious differences between solid welding wire and flux-cored welding wire in the welding process, which are mainly reflected in welding techniques, application characteristics and occasions of use. The following is a detailed analysis of the differences between the two:

I. Differences in welding techniques

1. Solid welding wire: When welding, the welding wire is mainly melted by arc heat and then solidified to form a weld. The operation is relatively simple and mainly depends on the proficiency of the welder and the performance of the welding equipment.
2. Flux-cored welding wire: Flux-cored welding wire contains welding rod core wire and flux powder. During welding, the flux powder will burn and produce gas, which helps to form the weld and stabilize the welding process. When using, it is necessary to control the welding current, arc voltage and welding speed to ensure the welding quality.

II. Application characteristics

1. Solid welding wire: Due to its simple operation method and good welding performance, it is widely used in the welding of various materials, such as carbon steel, stainless steel, etc.
2. Flux-cored welding wire: The application of flux-cored welding wire is affected by its internal flux powder and can adapt to different welding needs, such as low hydrogen type, ultra-low spatter type, etc. In addition, flux-cored wire has unique advantages when welding some special materials, such as aluminum, copper and their alloys.

III. Occasions of use

1. Solid welding wire: Mainly used for general industrial welding, such as construction, bridges, ships, etc.

2. Flux-cored welding wire: Due to its unique advantages in welding special materials and complex environments, flux-cored welding wire is widely used in welding in industries such as petroleum, chemical industry, and electric power.

IV. Summary

There are obvious differences between solid welding wire and flux-cored welding wire in welding techniques and applications. Solid welding wire is easy to operate and suitable for general industrial welding; while flux-cored welding wire has advantages in welding special materials and complex environments due to the unique properties of its internal powder. The choice of welding wire needs to be determined according to specific welding requirements and material characteristics. In addition, with the development of science and technology, both welding wires are constantly undergoing technical improvements to improve welding quality and efficiency.
