E3 Welding Process
We’ve borrowed this superior method of welding from race car and motorcycle frame manufacturing where a secure weld is extremely crucial. You can see that the E3 welding process allows the weld to penetrate the full thickness of the tube.
The industry standard tube finishing only allows for the weld to penetrate the thin edge, not penetrated to the end of the tube. The tube isn’t bonded together so much as stuck together, making a weak weld. This is one of the main problems plaguing the industry and a major reason for frame breakage.
