Sentences describing electric welding

1, when welding, the heat source will quickly melt the metal at the seam of the weldment and the filler metal added when necessary to form a molten pool, which will extend with the movement of the heat source and form a weld after cooling.

2. Align the covered electrode with the weldment. Then gently cut the covered electrode on the surface of the weldment like a match, ignite the arc, and then quickly lift the covered electrode a little distance to make it burn stably.

3. Align the end of covered electrode with the weldment, then bend the wrist downward to make covered electrode slightly contact with the weldment, then quickly lift the covered electrode for a short distance, and level the wrist after igniting the arc to keep the arc burning stably.

4. When covered electrode moves to the end of the weld bead, make a circular motion with your wrist until the arc pit is filled, and then the arc is disconnected.

5. The end of the covered electrode continuously moves along the circumference or oblique circumference, and continuously moves forward. This operation can make the molten pool exist for a long time and the metal temperature in the molten pool is high, which is beneficial to the precipitation of oxygen, nitrogen and other gases dissolved in the molten pool and the floating of slag.

6. First, clamp the welding handle on the covered electrode, connect the bottom line to the object to be welded, start the welding machine, and then start the operation with the welding cap in both hands.
