What are the contents of welder training?

We must first know what electric welding is. Electric welding is a kind of welding operation that uses covered electrode to melt metal parts at high temperature where arc connection is needed.

If you want to learn electric welding, you must first learn mechanical drawing, understand drawings and welding symbols, understand the position and method of welding, and master the material structure, welding principle, operation technology, actual operation method and detection.

When welding, the covered electrode keeps an included angle of 45 degrees with the iron plate, which is beneficial to the even distribution of molten iron and the smooth welding joint.

When welding, keep your hands steady, and your arms must be clamped to avoid shaking, so as to weld evenly and beautifully. Sawtooth and wave point welding are generally used in welding to make the weld line clearer.

Because molten iron is easy to fall off during overhead welding, spot welding should be adopted, which will make the welding more firm. At the end of the circle drawing, covered electrode should make a circular motion at the arc pit. When it moves to the end of the weld, the arc will be broken again until the arc pit is filled.

When replacing the covered electrode or temporarily stopping the arc to finish, when covered electrode moves to the end of the weld, he will stop at the arc pit for a while, slowly lift the arc, and then lead to the base metal groove at the edge of the weld. At this time, the molten pool will gradually shrink, and there will generally be no defects after solidification.

These are just the basic theoretical knowledge and skills of learning electric welding, but these need to be mastered slowly in theoretical and practical teaching and skillfully completed a process of technological requirements.

In this process, we should first learn with an open mind, remember the key and difficult points of technology, as well as the skills needed in welding and basic knowledge. We should study hard and practice hard to meet the basic requirements of welders.
