The manufacturer of friction stir welding tools tells you why friction welding has developed rapidly at home and abroad and is widely used, which is due to its own series of advantages. These advantages include the following aspects:

1. The welding quality of the joint is good and stable. The scrap rate of aluminum-copper transition joints produced by low-temperature friction welding in my country is less than 0.01%; the boiler factory uses friction welding instead of flash welding to produce economizer coils, and the welding scrap rate is reduced from the original 10% to 0.001%.
2. Suitable for welding dissimilar steel and dissimilar metals. The manufacturer of friction stir welding tools tells you that friction welding can not only weld ordinary dissimilar steels, but also dissimilar steels and dissimilar metals with very different mechanical and physical properties at room temperature and high temperature, such as carbon structural steel—high-speed tool steel; copper—stainless steel Wait. In addition, it can also well weld those dissimilar metals that produce brittle alloys, such as aluminum-copper, aluminum-steel, etc.
3. The weldment has high dimensional accuracy. For diesel engine pre-combustion chambers produced by friction welding, the maximum error in the overall length is ±0.1 mm. The manufacturer of friction stir welding tools tells you that some special friction welding machines can ensure that the length tolerance of the weldment is soil 0.2 mm, and the eccentricity is less than 0.2 mm. Therefore, friction welding is used not only to weld blanks, but also to weld assembled finished products.
4. The welding machine has low power and saves electricity. Compared with flash welding, friction welding saves about 80~90% of electric energy.
5. Friction stir welding tools manufacturers tell you that the workplace of friction stir welding is hygienic, without sparks, arcs and harmful gases, which is conducive to environmental protection and is suitable for automatic production lines together with other advanced metal processing methods.
