Argon-arc welding technology is one widely applied welding technology which rapidly develops at home and abroad. Due to the argon-arc welding can be used in almost all metal materials’ welding and can obtain high quality welding joints, so the argon-arc welding becomes a kind of important welding method in atomic energy, aerospace, petrochemical, machinery, shipping, transportation, light industry and textile and other industries.
In the past ten years, argon-arc welding has become an indispensable welding method in the metal welding process. The mechanization and automation degree of argon-arc welding have been greatly improved. And the argon-arc develops toward the NC direction which controls more divisors. Manual argon-arc welding tungsten electrode not only can obtain high quality weld joint, but also has the unique and favorable function of single-side welding and two-sided shaping, thus the argon-arc welding being received much attention both at home and abroad welding circles.
Besides the above points, other reasons why manual argon-arc welding tungsten electrode obtains wide applications and attention are mainly the following advantages:
1, argon-arc welding adopts inert gas to protect, thus reducing the burning loss of alloy elements and getting dense and high quality welded joints.
2, The arc of argon-arc welding is stable, heat is concentrated. The temperature of arc column is and heat-affected zone is narrow. In addition, welding stress, deformation and crack tendency are small.
3, Argon-arc welding belongs to visible arc welding, which is convenient for manufacturers to observe in the welding process and it is easy to operate.
4, Arc-welding almost can weld all metals, especially refractory metal. It is easy for arc-welding to oxidize metal, such as titanium, magnesium, aluminum and their alloys.
5, Arc-welding is not subject to limitations of welding position and arc-welding can take the gamut of welding.
6, It is easy to realize mechanical and automatic control.
Tungsten and molybdenum manufacturer-Zhengzhou Sanhui Co., Ltd has being dealing in refractory metals for over 24 years. Come to us for titanium, molybdenum and other metals.
