Problems solved by technology
Due to the difference in the height of the students and the different types of exercises, it is necessary to spot weld the steel bars at different positions on the column every time. After a long time, there will be a lot of welding scars and splashes on the column, which is very difficult to clean, and the solder joints are not easy for beginners. It is firm, and the test board is easy to fall and hurt students. Therefore, it needs to be updated and repaired frequently, which increases the teaching cost
When practicing vertical welding or horizontal welding, the test board is often held in one hand and the welding torch is held in the other. The arc light can easily hurt the eyes of the students, and if the students want to practice overhead welding or welding at a certain angle, it is time-consuming and laborious, which is extremely inconvenient

Description
technical field [0001] The invention relates to the field of electric welding teaching tools, in particular to an electric welding teaching experiment device. Background technique [0002] Electric welding is commonly known as electrode arc. It is a kind of welding operation realized by using the electrode to melt the metal parts to be connected through the arc at high temperature. This skill needs to be practiced slowly to be familiar with and mastered. The existing teaching electric welding operation frame is basically A column about 1 meter high is fixed on an iron base. During teaching, students spot-weld two steel bars at a suitable position on the column according to their own height, and place the correct test plate on the two steel bars. Practice flat welding or overhead welding, and then remove the two steel bars welded on the column after the practice. Due to the difference in the height of the students and the different types of exercises, it is necessary to spot...
