How to Ensure the Welding Quality of Flatbed Trailer?
It is very important to know the manufacturing process of a flatbed semi trailer. This will help
you when inspecting the final product and making a decision prior to purchasing it. This
knowledge will help you assess the quality of your trailer and whether it meets the set
standards in the industry. This will help you stay safe from individual workshops that use
sub-standard production methods. Here is what to look for in a flatbed semi trailer.Cutting——
A CNC cutting machine is used to cut out the steel plates including the web plate, reinforcing
plate, and accessories. In other words, the machine is used to cut all steel plates required to
make a complete semi flatbed trailer. Punching holes on the steel sections is important
because it reduces the weight and stress of the trailer. In addition, punching increases the
strength of the beams leading to a robust construction.Bending——
The next step after cutting the steel plate is bending according the drawing. Every manufacturing
process starts with a drawing of the final product. Hence, the manufacturers must use the
dimensions and shape on the drawing when bending the steel. A fixture is used to fix the
components to ensure that they are vertical and straight. This stage involves correcting and
measuring to ensure that the plate is in the right dimension, straight, and vertical.
Several components of a trailer require welding including the main beam, cross beam, spring
brackets, and the floor. Welding is a very important step in the manufacturing process. It
must be done in the right way to ensure that the final structure is strong enough to handle
heavy loads. Welding starts with the"H"beam, which is the main beam and proceeds to the
cross beams. The manufacturer must ensure that the 2 main beams are parallel to each other
when welding. The two joints onthe sides of the steel plate should be fully welded to ensure
that the plates and beams are strong enough. The main beam is usually welded by submerged
arc welding machine. Other parts such as the cross beams, plate, and accessories among
sereval others are welded by a welder.
After connecting all beams and plates through welding, manufacturer must check the strength
of the key positions. Sometimes, the process of joining heavy beams causes some joints to loosen.
Hence, repair welding and reinforcement is necessary before the trailer leaves the workshop.
