Electrode arc welding, the end of the Welding Electrode Suppliers and the workpiece arc burning between the heat generated by the drug electrode and the workpiece skin and core melt welding, welding deepening rapidly to form the core end of the small metal droplets, through the transition to the arc column partial melting of the workpiece surface, blending together to form pool. Drug skin melting process the gas and slag, not only the air around the pool and arc cut off, and the core and the molten solder, the base material a series of metallurgical reactions, to ensure the formation of weld performance. With the appropriate arc length and arc speed at work constantly move forward, gradually cooling and crystallization of liquid metal bath to form a weld. Welding arc has the following advantages:
1) The equipment used is relatively simple, relatively cheap and lightweight. Electrode (silver electrode) arc welding using AC and DC welding machines are relatively simple, the welding operation does not require complex auxiliary equipment, just with simple tools. Therefore, the purchase of equipment investment, and easy maintenance, which is one of the reasons it is widely used.
2) does not require auxiliary gas protection. Not only can provide filler metal electrode and the welding process and weld pool can produce a protective outer shielding gas to prevent oxidation, and has strong wind resistance.
3) is flexible and adaptable. Arc welding electrode for single or small quantities of products, short and irregular, anywhere space is not easy to achieve, and other mechanized welding seam. The place where the Welding Cables can be achieved can be welded.
4) Wide range of applications, suitable for most industrial metals and alloys used in welding. Appropriate choice of electrode arc welding electrode can not only welded carbon steel, low alloy steel, high alloy steel welding but also, and non-ferrous metals, the same can not only weld metal and welding dissimilar metals can also be used for cast iron welding and surfacing materials such as metal
The 5th China Jinan International Welding Electrodes and Cutting Equipment Exhibition will be held in Jinan International Convention and Exhibition Centre on September 18, 2010 20 th grand opening. Exhibition a total of four exhibition halls, 1,500 booths and 35,000 square meters exhibition area, after the accumulation of the fourth, has become the Shandong and northern China's largest exhibits species, the highest grade industry event, the people in the industry as Shandong Industrial Equipment first exhibition!
The exhibition organizer in nearly 100 major newspapers, magazines, websites and other media such thing to launch this show, the major news media attention, have have continuous coverage.
The exhibition "Innovation in China, manufacturing Shandong, harmonious development" as its theme, "honest services, to create industry-leading development platform" for the purpose by the strong support of government departments and enterprises, the show has been well-known enterprises in Shandong visit procurement. Heavy Duty Truck, Geely, young people, in cars, scooters, Qilu Software Park, the tide in the record, ZTE and other enterprises. The exhibition site will be a comprehensive display of all kinds of welding and cutting equipment, welding materials and a variety of welding and cutting equipment and other products, manufacturing firms, an ideal venue for professionals to harvest the forefront of the market.
The organizing committee said that as of now, enroll in the enterprise exception received inside and outside welding and cutting companies have first set the booth of a large area, there are a number of well-known domestic enterprises have been identified booths, 70% of customers have signed up, and reporting a very large area, again outside the industry felt the hot Shandong Welding Rod and Cutting Fair "and charm.
