[0002] Mining machinery and equipment manufacturing industry is an important basic industry supporting the development of mining industry. It involves mining, mineral processing, ore processing and mineral transportation. Square metal parts in mining machinery and equipment usually refer to metal parts with square cross-sections. These parts can be structural or functional, used to support, connect or be part of the machinery. In mining machinery, these square parts may need to bear greater forces and stresses. When welding square parts of existing mining machinery, workers usually need to butt two matching square parts together, and then repeat the welding and flipping operations at the gaps on the four sides of the square. In this process, since the initial single-sided welding is not strong enough, the initial single-sided welding position is easily broken by pulling during the subsequent flipping and welding, resulting in the square parts being not firmly welded. In view of this, the present invention proposes a welding device for manufacturing mining machinery and equipment with high safety performance to make up for and improve the shortcomings of the prior art.
