Different parts of the radiator is welded, the quality of welding directly affects the quality and service life of the radiator. The welding process is mainly filler welding and body welding, relatively speaking, the body of the corrosion resistance is good, and there is a uniform welding scar, without grinding; filler welding corrosion resistance is poor, smooth and smooth surface. Consumers in the purchase of the main to see whether the welding is firm, the appearance of the weld is uniform, there is no rugged phenomenon. However, the weld can not be too strong and smooth, because the excessive grinding process is likely to cause the strength of the welding site to reduce, resulting in running water leakage.
