Resistance welding (also known as pressure welding) is a commonly used welding method. It uses the resistance heat generated by the current flowing directly through the contact surface between the workpiece itself and the workpiece to locally heat the workpiece to a highly plastic or molten state. The finished welding process. The main features of resistance welding are:
(1) Low voltage, high current (several thousand to several tens of amps), the time required to complete a welded joint is extremely short (0.01 ~ a few seconds), so the productivity is high.
(2) Heating and pressurization are performed simultaneously during welding, and the joint is welded under pressure.
(3) No metal or flux is required for welding.
There are many welding methods for electric resistance welding. According to the shape of the joint, it can be divided into spot welding, seam welding (roll welding), butt welding.

Soft Close D Shape Toilet Seat
A D-shaped Toilet Seat is a specially designed toilet seat that is usually used in conjunction with a D-shaped toilet.The design of the D-shaped toilet seat has been optimised from the traditional toilet seat to better fit the shape of a D-shaped toilet, thus providing a better user experience.

In terms of material, D-shaped toilet seat can be made of a variety of materials, including urea-formaldehyde material and density board material. Each of these materials has its own characteristics, with urea-formaldehyde material being hard and resistant to wear and tear, while density board material has a smooth surface and is easy to process. Consumers can choose the right material according to their needs and budget.
It should be noted that, because the shape and size of the D-type toilet seat is more special, so when you buy it, you need to make sure that it matches perfectly with the D-type toilet at home.
Overall, the D-shaped toilet seat is a design that combines comfort and practicality, and is suitable for families with high demands on quality of life. When making a choice, consumers should make comprehensive considerations in conjunction with their needs and usage environment in order to select the most suitable product for them.
