1, the most suitable for Aluminium Welding Electrode torch is drawing style, if you can not use this gun, try to use the shortest gun in order to maintain the gun straight; only use argon as a shielding gas; only when welding aluminum gunmen using push method.
2, if you find wire problem, you can try a bigger size than the conductive wire head.
3, the most commonly used when welding aluminum wire is softer standard wire. While the other will have a hard number (easier to wire), it is mainly used for higher hardness and strength requirements of the welding operation.
4, before the start of the welding aluminum surface oxide layer to do the cleanup, using a dedicated stainless steel brush to remove the oxide layer.
5, good welding crater fill at the end to prevent cracks. One way is in the welding torch will stay in the pool in a few seconds.
1, to promote the progress of welding automation Welding variety of restructuring the mid-1980s, developed countries accounted for welding consumables welding rod ratio of about 50%. 2004 Europe, North America (U.S. and Canada), in Japan in the consumption of welding consumables, welding rod ratio are less than 20%, Table 2, that is, the current self-developed technology and semi-automated welding, have been accounting for more than 80% of welding work.
2, welding steel to promote scientific and technological progress and quality of replacement species are trying to enhance our powers made of steel from the steel in the direction of power in recent years has introduced a large number of upgrades and high-performance high-quality steel, in particular the production of iron and steel industry equipment and technology has made significant progress, for example, will come into operation more than a dozen sets of plate mill, its performance will exceed the existing mill in Japan and the United States as the world's new generation of modern plate mill for the realization of controlled rolling and cooling ( TMCP) technology, production volume, high-performance plate, laid the foundation equipment.
3, the towers, ordinary welding, competitive prices should be promoted market-oriented production and consumption in China is currently the most common welding materials, including carbon steel welding rod end 422, etc., HJ431 flux, ER50-6 copper wire, etc. products, due to capacity expansion, over-supply, so that our ordinary domestic sales and export of welding materials prices, only the equivalent of the international market price of similar high-quality welding of 50% to 60% of some welding company also adopted a "low-cost, low quality, low price "means the vicious competition, so many users complained that some of the country in recent years, 422 knot quality welding electrodes and other common, not only failed to progress, but deteriorated. Foreign markets to reflect the general export some of our welding is "low quality parallel imports", though cheap but quality is good, can only be used in minor projects, to China's "image of welding consumables," caused a bad influence.
