SMAW is to look under the mask and stop operation. Due to poor visibility, poor working conditions. Thus to ensure the welding quality, not just request a more skilled operation techniques, should also be noted the force is highly concentrated. For beginners to practice should pay attention to: current suitable electrode to the positive, the arc is short, do not fast welding speed, trying to average.
Prior to welding, liquidation of the workpiece joints on both sides of 20mm within the exterior clean (eliminate rust, oil, water), and the electrode end of the metal core exposed in order to stop the short-circuit arc. Arc approach has two kinds of percussion and friction law; which the friction law analogy is easy to control, suitable for beginners arc operation.

SMAW is to look under the mask and stop operation. Due to poor visibility, poor working conditions. Thus to ensure the welding quality, not just request a more skilled operation techniques, should also be noted the force is highly concentrated. For beginners to practice should pay attention to: current suitable electrode to the positive, the arc is short, do not fast welding speed, trying to average.
Prior to welding, liquidation of the workpiece joints on both sides of 20mm within the exterior clean (eliminate rust, oil, water), and the electrode end of the metal core exposed in order to stop the short-circuit arc. Arc approach has two kinds of percussion and friction law; which the friction law analogy is easy to control, suitable for beginners arc operation.
(1) scratch --- first electrode at the weldment, then scratch like program match in weldments appearance quietly ignited arc Aluminium Welding Rod, and then move to the electrode lift the 2-4mm, and stable extinguished.
(2) alignment of the percussion method --- the electrode end of the weldment, and then trick the next bend, so that the electrode subtle touch weldment, and then move to the will filed 2 ~ 4mm welding rod ignited the arc after trick flat, so that the arc Ensure stability extinguished. This arc approach does not make welding pieces of the appearance of scratches, but also not subject to the limitations of the the weldment appearance of size, shape, so the arc approach is mainly used in the consumer. But the operation is difficult to control, need to progress the proficient level.
Arc required to pay attention to the following matters:
1) arc Department should be no oil, water, rust, in order to avoid pores and slag.
2) electrode in contact with the weldment increase speed to be appropriate, too fast, difficult to arc, the slow welding wire and stick together to form a short circuit.
(2) transported Article
The transport bar is the most important aspects of the welding process, which directly affects the forming and the intrinsic quality of the weld surface. Ordinary circumstances, after the arc ignition electrode there are three fundamental movement: direction toward the bath gradually taken to gradually move along the welding direction, horizontal swing.
Electrode toward the bath the direction of gradually sent - both to add to the bath metal, in order to continue to adhere to a certain degree of arc length, in the condensation of the electrode and thus electrode feeding speed should be the same as the speed of condensation with the electrodes. Otherwise, the attack off the arc, or stick on the weldment.
Electrode move along the welding direction --- as the electrode from time to time condensation, and gradually form a weld. Electrode moving too slow, the weld is too high, too wide, the shape is not uniform, the onset of burn-through phenomenon when welding sheet metal; the moving speed of the electrode is too fast, the electrode and the weldment will condense the uneven weld bead narrow, as well as episodes of incomplete penetration phenomenon. Electrode move should be moving direction at 70-80 degree angle, so that the condensation of metal and slag into the front of, or slag flow of arc in front of the formation of defects such as slag. (1) scratch --- first electrode at the weldment, then scratch like program match in weldments appearance quietly ignited arcWelding Rod, and then move to the electrode lift the 2-4mm, and stable extinguished.
(2) alignment of the percussion method --- the electrode end of the weldment, and then trick the next bend, so that the electrode subtle touch weldment, and then move to the will filed 2 ~ 4mm welding rod ignited the arc after trick flat, so that the arc Ensure stability extinguished. This arc approach does not make welding pieces of the appearance of scratches, but also not subject to the limitations of the the weldment appearance of size, shape, so the arc approach is mainly used in the consumer. But the operation is difficult to control, need to progress the proficient level.
