What is a sealing welder?
welding weld is a welder that performs the primary function of sealing joints. The seals are commonly used in gas or liquid containers to contain gaseous or liquid substances and prevent leakage. The presence of welds of seals also prevents the entry of gases or fluids into specific areas outside the limit, where they can cause corrosion or other damage. There are two types of prepared galvanized joints, regular and ventilated that can be connected by seal welding; There is also a third prepared galvanized joint that does not require a weld of seals. For conventional joints, it is necessary to ensure that the welds of seals are not so porous to allow any kind of escape. Ventilated joints are joints that have holes or holes in them to allow the gas to escape out. When applying the welds of the seal on the ventilated joints, it is important to ensure that the holes are located in the right places; The accumulation of gas can damage Joijinak.
It should be borne in mind that the welds of the seals are only located as a detention measure and should not be expected to add to the joint strength. It is necessary for the designer and the manufacturer to check that the location of the seal agrees with the requirements for the code set by the American welding company (AWS), although the code violation is in some cases allowed to affect the flexibility of the joints. It is also necessary to ensure that the weld of the seal does not end up some undesirable structural function or that the presence of welds of seals does not affect the ultrasound inspection too badly.
The welder must be well qualified to perform work, and must follow the sound welding procedures in the production of seal weld. Sound seal welding procedures include adherence to specified weld sizes and heat input, selecting the correct electrode shape and tracking the correct welding procedure. The correct time of heating and welding pressure is necessary to ensurePuppies to achieve a complete merger and that there is no chance that the weld of the seal can burst.
The application of seal welds is common in the food processing and engineering industry. In addition to the pipes and containers, the steel elements of the seal welding are uncovered to prevent rust. In the door of the refrigerator and cars, the pin is used, which is also known as cropping or rubber lock.
