The difference between flux cored wire and solid wire？

Difference

Productivity

Compared with manual welding electrodes, the continuous welding method of flux-cored welding wire has high production efficiency. Compared with solid welding wire, the welding spatter of flux-cored welding wire is less and the welding seam is well formed, so the time of spatter removal and surface grinding of the welding seam are reduced. 

Adaptability to steel

Compared with solid welding wire, since flux-cored welding wire generally transitions alloy elements through flux core, the alloy composition can be adjusted from the formula as easily as manual welding rod to suit the requirements of the steel to be welded. The solid core welding wire needs to be re-smelted every time the alloy composition is adjusted. It has many processes and is difficult to control, so it is difficult to meet the requirements of less dosage and more varieties. And some alloy steel solid wire has poor drawing performance, and it is difficult to draw the required wire. At this time, the flux-cored wire shows its unique advantages.

Worker Operation Requirements

Flux-cored welding wire has low requirements for workers' operation level: compared with manual welding rod, the operation of downward feeding is omitted; compared with solid-cored welding wire, its current and voltage adaptability range is wide. The cost

Compared with manual electrode and solid wire, the price of flux-cored wire itself is high. However, for large enterprises, after using flux-cored welding wire, the production cycle is shortened and the quality of the weld is easy to ensure, so the comprehensive benefits are very high.

Moisture resistance

Ordinary flux-cored wire has a continuous gap on the side of its steel skin due to the constraints of its manufacturing form. Therefore, the shelf time of the flux-cored welding wire after opening the package should not be too long to prevent excessive moisture absorption and affect the welding quality.
