2. Welding Electrodes - Welding electrodes are metal rods that are used to conduct electricity and create an arc. They are coated with a flux that helps to protect the weld from contamination and oxidation.
3. Welding Wire - Welding wire is used in the MIG welding process to feed the welding arc with a continuous supply of wire. It is available in different thicknesses and materials, such as stainless steel, aluminum, and mild steel.
4. Welding Helmets - Welding helmets are designed to protect the welder's eyes and face from the intense light and heat produced during welding. They come in different styles and designs, including auto-darkening helmets that automatically adjust to the brightness of the welding arc.
5. Welding Gloves - Welding gloves are used to protect the welder's hands from heat, sparks, and other hazards associated with welding. They are made from materials such as leather and Kevlar and come in different sizes and styles.
6. Welding Safety Glasses - Welding safety glasses are designed to protect the welder's eyes from the intense light and UV radiation produced during welding. They are available in different shades and styles.
7. Welding Filler Metals - Welding filler metals are used to add material to the weld joint to create a strong, durable bond. They come in different materials, such as stainless steel, aluminum, and bronze.
8. Welding Clamps - Welding clamps are used to hold the metal being welded in place during the welding process. They come in different sizes and styles, including C-clamps, locking pliers, and magnetic clamps.
9. Welding Flux - Welding flux is used to protect the weld from contamination and oxidation during the welding process. It is available in different types, including powder, paste, and liquid.
10. Welding Gas - Welding gas is used in the TIG and MIG welding processes to shield the welding arc from contamination and oxidation. It is available in different types, including argon, helium, and carbon dioxide.
Chemical industry continues to pressurize energy-saving and emission reduction
On March 11, Xie Zhenhua, deputy director of the National Development and Reform Commission, and Zhang Lijun, deputy director of the State Environmental Protection Administration, addressed a press conference during the First Session of the 11th National People's Congress. They highlighted that China made significant progress in energy saving and emission reduction last year, but with less than three years remaining to meet the targets set under the "Eleventh Five-Year Plan," the challenge remains substantial. In the coming years, more stringent measures will be implemented to accelerate the transition toward sustainable development, placing even greater pressure on energy-intensive sectors like the oil and chemical industries.
Xie Zhenhua noted that in 2007, China achieved a 3.27% decrease in energy consumption per unit of GDP, while total sulfur dioxide emissions dropped by 4.66% and chemical oxygen demand fell by 3.14%, marking the first time both metrics declined simultaneously. This success was attributed to government efforts to restrict high-energy and high-emission industries, as well as to phase out outdated production capacity. For instance, Jiangsu alone shut down over 2,000 small chemical companies. Additionally, ten major energy-saving projects were launched, and 1,000 enterprises were encouraged to adopt energy-saving practices. New policies on pricing, taxation, and fiscal incentives were introduced, and the Energy Conservation Law was enacted to support these goals.
Looking ahead, the task of meeting energy-saving and emission-reduction targets over the next three years remains challenging. Despite ongoing efforts to eliminate outdated industrial capacity and reduce the production of "two high" (high energy consumption and high pollution) products, China's rapid economic growth and heavy industrial structure continue to pose obstacles. Some previously approved projects have now raised environmental concerns. Therefore, 2008 is considered a critical year for fulfilling the "Eleventh Five-Year Plan" objectives. All industries, including the chemical sector, will face stricter evaluations and regulatory scrutiny.
It is expected that the energy-saving and emission-reduction performance of thousands of key enterprises will soon be disclosed, with approximately one-third being oil and chemical companies. In May and June this year, the State Council will also release provincial-level results. Provinces and key enterprises that fail to meet their targets will need to provide explanations, implement corrective actions, and face restricted approvals. Meanwhile, Zhang Lijun emphasized that to ensure good air quality during the Beijing Olympics, six regions—including Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, and Shandong—must complete industrial restructuring tasks for chemical and building materials companies before the event.
