In order to avoid large deformation of welding, welding nuts are usually used on thin plates of about 6mm, and at the same time, the welding after welding is relatively beautiful. China Wood Screws Manufacturers Introduction: During the welding process, a DC power supply must be used and the cathode should be connected to one end of the welding wire.
Before welding, the grease, rust and other dust on the welding parts should be removed to avoid weld seams. As a protective gas, pure argon is used. When the current is 50A, 150A, the flow rate of argon is 8~10L/min, and the current is 150A, 250Ω. It should reach 12 to 15 liters per minute.
During welding, the working environment must be ventilated, ventilation in the room must be controlled, and mesh guards must be used for welding. The angle between the weld and the tungsten centerline should be maintained at 80-85°. This has the advantage of better protecting the weld.
The angle between the filler wire and the welding surface must be kept within 10°. The length of the tungsten electrode protruding from the gas nozzle is about 5mm, the length at the exposed position such as the corner is about 2-3mm, and the length at the deep part is about 6mm.
