The automotive industry revolutionized people’s mobility and is the pillar of industrial development. It is one of the biggest industries, for even global economic development depends on it. Even after the disastrous pandemic, the automotive industry’s value is over 2.9 trillion dollars and to grow at a CAGR of 3.11%. It is why many reputed automotive body parts manufacturers are in high demand. And their use of the best TWB or tailor-welded blanks is also increasing worldwide. It has many advantages, like lightweight, increased strength, reduced costs, improved safety, etc.
So, in this article, learn about tailor-welded blanks made by the best automotive body parts manufacturers, including the many advantages.
What is TWB or tailor-welded blanks?
Statistics confirm that over 60 million vehicles hit the road every year and consume over 50% of oil production worldwide. Hence the necessity to make light vehicles that consume less oil which is beneficial for the owner and the environment is increasing worldwide. In these circumstances, a new technology called TWB has been useful in the automotive industry in recent years. It is possible to reduce their weight by using it in the body-in-white structural parts of the vehicles, hence the oil consumption. Indirectly, it will reduce the need for producing more oil from fossil fuels that are causing climate change to damage mother earth. So, what exactly are tailor-welded blanks?
TWB or tailored welded blanks are semi-finished parts made from sheets of various alloys, coatings, thicknesses, and material properties. Using laser and other weldings to make these different alloy steels join and, by coating, add strength. Experienced automotive body parts manufacturers process the TWBs with the right material at the right place to enable flexible design options. It will have enough thickness for use in places that need strength and thin at places where there is no need for strength. Hence there are many advantages of using the tailor welded blanks.
Advantages of tailor welded blanks
Automotive is a significant industry that uses different tailor welded blanks to make many parts with the right strength and thickness in the right place. Aluminium is one of the lightest metals for multiple uses in the car to reduce its weight and fuel consumption. Since aluminium is expensive, it could be alloyed with other metals to form tailor-welded blanks for making many vehicle parts. It includes B-pillars, inner door panels, side panels and others to be light without compromising the high safety requirements. There are many advantages of using tailored welded blanks made by the best automotive body part manufacturers, including the following.
- Many OEMs or original equipment manufacturers approve of using TWBs as they reduce production costs while increasing safety.
- It saves money by reducing costs and reduces the time and effort for assembling the vehicle parts as it eliminates the need to apply additional reinforcements on finished parts.
- Increases crashworthiness because of the strong aluminium protecting the vehicle and passengers during crashes
- Provides dimensional accuracy because of the latest laser technology cutting of blanks from different alloys to be perfect for the purpose
- Offers excellent corrosion resistance because aluminium blanks resist corrosion in the atmosphere and only rust when immersed in aqueous solutions
- Useful in various application areas in vehicles like floor panels, inner panels, side skirts, integral subframe, chassis technology, longitudinal/cross members, backrests, etc.
