2. Before the work, the welder must wear a variety of labor insurance products to prevent burns, injuries, and electric shock.
3. Before welding, check whether there are flammable or explosive materials around the working site, and whether the electrical insulation of the electrical system is good, etc., to prevent electric shock, fire, explosion and other accidents.
4. Conductive articles are not allowed on the welding machine. When the welding machine is turned on, it is necessary to push the foot quickly. After the operation is normal, the machine can be operated. When leaving the site, the welding machine should be turned off.
5, welding in the container, there must be insulation pads and low-voltage lighting, blast or ventilation facilities, and some people need to be monitored outside.
6. It is strictly forbidden to weld the closed container with pressure and flammable gas and flammable liquid. If necessary, there should be an air outlet and the container should be cleaned before operation.
7, ascend welding, must be stable before operation, high-altitude operations should comply with the relevant safety procedures for high-altitude operations.
8. When moving the wire, it is necessary to prevent the cutting and the damage. When the wire passes through the channel, the protective material should be added on the line. When the welding machine moves, the power is cut off first.
9. When working near inflammable and explosive materials, you should contact the relevant personnel and take relevant measures. After the work is over, check the site to prevent fires and explosions.
10. The arc welding electric welding transformer must have a casing, the primary joint must be closed, the ground wire should be in good contact with the work, and it can be operated only after being clamped and fixed by appropriate methods.
11. After the work is over, the water, electricity and gas valves or switches should be closed, the cable and related pipe should be well-discended, the site should be cleaned, the fire extinguishing should be extinguished, and the welding machine and related tools should be put back into the proper position.
Extrusion aluminum shell is a type of aluminum shell that is created by the process of extrusion. This process involves pushing aluminum through a die to create a specific shape or profile. The resulting aluminum shell is strong, durable, and lightweight, making it an ideal choice for a wide range of applications.Extrusion aluminum shells can be used in a variety of industries, including electronics, automotive, aerospace, and construction. They are often used as enclosures for electronic components, such as circuit boards and power supplies. They can also be used as structural components in buildings and vehicles.One of the benefits of extrusion aluminum shells is their versatility. They can be customized to meet specific design requirements, including size, shape, and finish. They can also be easily modified or adapted to accommodate changes in design or function.Another advantage of extrusion aluminum shells is their durability. They are resistant to corrosion and can withstand harsh environments, making them suitable for use in outdoor applications. They are also able to withstand high temperatures and can be used in applications where heat dissipation is important.Overall, extrusion aluminum shells offer a range of benefits that make them a popular choice for a variety of applications. Their strength, durability, and versatility make them an excellent choice for a wide range of industries and applications.
