Specific method of total **** three steps, hierarchical, easy to remember and understand.

The first step, learn to regulate the current (understand can).

The problem of regulating current accompanies the welder's entire career, and determines the quality of welding. So this issue must be raised first, in order to cause the beginner enough attention. But here is not necessary to the current problem thoroughly understand, as long as there is a preliminary understanding on the line.

The method is to adjust the current according to the diameter of the weldment and electrode. Generally speaking, the weldment in about 5mm or thicker plate, usually using the diameter of 2.5, 3.2, 4.0 welding rod. The current is calculated by welding electrode direct * 40 = welding current. This will determine the current, and then just draw a picture of the cat.

The second step, the key is to stabilize the hand control efforts (understand can).

Control is the whole process of welding know-how. Basic control includes: hand stability, the height of the arc length, electrode inclination. Flat welding, for example, the current 130, electrode 3.2. hand welding handle does not shake, and maintain a uniform speed straight line walking (this is a basic skill, can be slowly honed in the future, at this time there is no need to force).

Arc length height (i.e., the distance between the tip of the electrode and the weldment), in the process of transporting the electrode, always keep 2-3 millimeters can be. The inclination of the electrode (i.e., the angle between the electrode and the weldment) is always maintained at 70-80 degrees. This operation will be able to get a flat and proportional qualified weld.

The third step, start welding (try to master).

The easiest way to start welding and notes, with a current of 130, electrode 3.2, for example. When holding a welding handle with a welding rod to knock the intention of the arc of the weldment, pay attention to the welding rod should be tilted to scratch the weldment, not perpendicular to the weldment, so as to avoid the sticking of the welding rod, so that the arc of the smooth. This way to start welding, all the problems behind can be watered down and smooth.

Referring to the above three-step method, usually within ten minutes, even beginners, you can pick up the welding handle, the pattern of comparison.

Beginner's welding techniques

Welding hands need to keep the burner smooth, the arms must be clamped to avoid shaking, so that the welding is even and beautiful.

Burning welding, welding rod and iron plate angle to maintain a 45-degree angle, is conducive to the even distribution of iron, burned out of the welding rod is smooth. In the back welding operation, because the iron is easy to fall down, so you need to use the form of spot welding, so that the burning is more solid.

When the welding rod moves toward the upper edge of the weld, it makes a circular motion at the arc crater until it fills the crater and then pulls off the arc.

When replacing the electrode or temporarily stopping the arc to finish, move the electrode to the end of the weld, pause at the arc pit, lift the arc slowly, and then lead it to the base metal bevel at the edge of the weld. At this point, the molten pool will gradually shrink, and there are generally no defects after solidification.
