How to weld aluminum material with argon arc welding machine
No thorium tungsten or cerium tungsten welding steel pole with pure tungsten, alternating current, welding wire and base metal components. Similar aluminum heat quickly, the temperature of the base metal with the welding process in the continuous increase, to grasp the welding speed and wire feeding speed (generally with the welding process, to speed up the best lining pad. Flow) the welding pool of aluminum is not good, not easy to end with the best fusion butt welding arc plate and arc plate. Aluminum easy arcing, should pay attention to stopping.
Argon arc welding machine for welding aluminium material needs AC welding machine.The oxide film of aluminum must be broken.
1) AC argon arc welding machine shall be used. The use of a cathode crushing needle in the process of welding produces three aluminium oxide (two aluminum oxide).2) the choice of black glass. Should be more than you usually weld stainless steel lenses plus one to two, in order to better see the molten pool.3) suitable material selection. Select the suitable filling material according to the aluminum material.4) the choice of gases. Rich argon gas (nitrogen + argon) and argon gas can be used in two ways.5) current selection. According to your personal habits, you can meet the requirements
