Volvo Trucks Joins Hanas Group to Open China's Road to Dangerous Chemicals

At the National Energy Work Conference in 2011, China’s natural gas consumption in the next five years is expected to increase to more than 25%. In the face of huge potential industrial demand, the matching of energy transportation must keep pace, and safe and efficient transportation guarantee is the basic prerequisite for the effective use of energy.

As one of the world's diversified energy solution providers, Hanas New Energy Group has long been committed to China's energy transformation. In order to become China's largest dangerous goods land transport company, Hanas Group is extremely strict on the requirements for remanufacturing transportation. In the previous rounds of comparison, the Hanas New Energy Group finally locked Volvo Trucks as the best choice for natural gas transportation teams. After a year of communication and running-in, Volvo Trucks has started cooperation with Hanas New Energy Group since February of this year. Formal cooperation.

It is reported that in this comprehensive transportation solution, Hanas New Energy Group and Wal-Huo Xiaohe have reached a total of 100 orders for trucks. Hanas’s models are all Volvo FM 4006×4 for LNG transportation. Products will be delivered in succession from August this year.

The requirements for trucks during the transportation of dangerous chemicals are extremely stringent, and the highest level of safety needs to be maintained, while strict national and international regulations must be met. Transporting dangerous goods means bearing higher safety driving responsibilities, and fulfilling this responsibility depends largely on vehicles that can ensure safe driving and drivers who can safely handle them, so as to reduce the risk of accidents. A safe transportation tool is to require that the transportation vehicle can balance safety and efficiency in short-distance or long-distance transportation, and the performance of the vehicle, such as: excellent road handling, overall power control capability, excellent braking effect and efficient auxiliary braking effect All of these play a vital role. The Volvo FM series selected by Hanas Group is for the transport of dangerous goods and is suitable for long-distance shipping tools. Its design in fire protection, static electricity, and fire protection configuration meets the European Agreement for the Transportation of Dangerous Goods by Road. "(ADR)" is able to excel in the transportation of dangerous goods such as oil and natural gas.

It is reported that Volvo was rated as the world's safest car, Volvo Truck Company was established in 1928. In Latin, VOLVO means "moving forward." Since the 1920s, the wheels of Volvo trucks have never stopped moving forward, until the creation of a new century of glory. Today, Volvo Trucks has become the world's second largest European truck manufacturer with products in more than 130 countries around the world. For centuries, trucks have been an indispensable means of transportation since they were initially used as a supplemental form of transportation such as carriages, railroads, and sea routes. Today, trucks have been given more meaning, focusing on environmental protection, efficient logistics, energy conservation, ergonomics and other aspects. Volvo has made great strides into the Chinese market through its own quality and performance.

Gas-shielded, flux-cored arc welding (FCAW-G) is a very popular and versatile welding process. It is used with mild steel, low-alloy steel and other alloy materials in a variety of applications, such as heavy fabrication, structural, shipbuilding and offshore. The two most common (but not exclusive) shielding gases used with the FCAW-G process are carbon dioxide (CO2) and a binary blend of 75% argon (Ar) / 25% CO2. Other blends, such as 80% Ar / 20% CO2, can also be used.
  
So which shielding gas, 100% CO2 vs. an Ar/CO2 blend, should you choose for your flux-cored welding? Each type offers some advantages and disadvantages. The factors of cost, quality and productivity should be considered when manufacturing decisions are made. The choice of shielding gas affects each of these factors, sometimes in a conflicting way. The merits of the two basic gas options for FCAW on steel applications will be the focus of this article.

Choosing a Shielding Gas for Flux-Cored Welding

Before getting into the particular advantages of the gas options, it is appropriate to review some basics. It should also be noted that this article only focuses on a few types of gases. As a more comprehensive reference, ANSI/AWS A5.32/A5.32M [Specification for Welding Shielding Gases," prescribes the requirements for shielding gases, defining requirements for testing, packaging, identification and certification. Additionally, it contains helpful information on ventilation during welding as well as general safety considerations.

How Shielding Gas Works
The primary function of all shielding gases is to protect the molten weld puddle and electrode from the oxygen, nitrogen and moisture in air. Shielding gases flow through the welding gun and exit the nozzle surrounding the electrode, displacing the air and forming a temporary protective pocket of gas over the weld puddle and around the arc. Both CO2 and Ar/CO2 blends shielding gases accomplish this purpose.

Some shielding gases make it easier to create the arc plasma, providing a current path for the welding arc. The choice of shielding gas also affects the transfer of thermal energy in the arc and forces on the puddle. For these issues, CO2 and Ar/CO2 blends will behave differently.
