Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a shipboard submerged arc welding device. Background Art

[0002] Submerged arc welding is a welding method in which an arc burns under a flux layer. It has the advantages of stable welding quality, high welding productivity, no arc light and little smoke. Therefore, when welding on a ship, a submerged arc welding device is used to weld the gaps in the hull to ensure the strength of the connection. In the prior art, when welding on a ship, the welding gun of the submerged arc welding device moves along the weld to perform welding.

When welding the ship position, the fixing part moves the protective cover forward, and the driving motor on the outer side of the protective cover drives the grinding wheel module to grind the narrower weld seam, so that the weld seam becomes an inverted trapezoidal state, thereby expanding the flow area of ​​the weld pool during welding, so that the molten iron in the weld pool can cover the entire weld seam, and the weld pool flows to a deeper part of the weld seam, thereby improving the welding strength of the weld seam. In addition, the grinding process is performed before the welding gun on the submerged arc welding device moves, so that the welding gun moves along the weld seam for welding, thereby ensuring the strength of the welding position and reducing the problem of cracking in the later stage.

[0016] In addition, by using a plunger to push the flux flowing downward, the problem of flux agglomeration affecting flow is reduced. When welding on a ship, the flux storage tank stores welding flux inside, and the flux flows out through the flux duct at the bottom. The driving cylinder on the fixed carrier plate drives the traction plate to move up and down, and the traction plate drives the plunger at the bottom to be inserted above the flux duct where the flux flows. The plunger moves up and down to push the flux to flow downward, and the plunger can break up the agglomerated flux, so that the flux can flow quickly to the weld for welding.
