Description

[0001] JIG APPARATUS FOR PRACTICING WELDING [0002]

The present invention relates to a jig device for welding practice.

Welding is a method by which heat and pressure are applied to the same or different kinds of metallic materials to bond them directly between solid bodies. This saves material, reduces airflow, improves product performance and life, improves joint efficiency, And is widely used in various technical fields due to its extensibility and density. Such welding work requires a certain level of experience and expertise as in other technical fields. Especially, the demand for the acquisition of welding qualification right now and the demand for it are increasing rapidly.

In the meantime, according to the Welding Attitude Regulations of the Welding Association of America, welding welding posture is largely 1G, 2G, and 5G according to the American Welding Association (AWS) , 6G, and 6GR. The letter "G" indicates a groove, and the letter " 3 " (Horizontal fixed), 2G is a horizontal posture (vertical fixed), 5G is an electronic three-dimensional (horizontal fixed), 6G is an electronic Means three (45) degrees.

The US Welding Association regulations are more and more recognized throughout the world, including the United States, because they conform to standards such as the American Society of Mechanical Engineers (ASME) and the American Petroleum Institute (API).

However, at present, there is no apparatus for easily practicing the welding posture required by various welding associations, so that there are difficulties in welding practice for various welding postures, and in addition, So that the user's discomfort is doubled and the efficiency of the operation is reduced.

In addition, in the high-temperature and high-pressure environments where the welding operation is performed, the various pipe structures are not fixed and accidents often occur. In addition, since the time or place restriction is large in performing the welding, There is also the inconvenience that it can perform.
