Description
Technical field
The present invention relates to electric welding machine technical field, in particular to a kind of multipurpose mariages narrow clearance welding gun.
Background technique
Narrow gap welding is a kind of efficient welding procedure, there are commonly " narrow gap twin wire gas shielded arc welding, narrow gap mariages
Submerged-arc welding, narrow gap bipolar electrode TIG weldering ".Also develop and produce " narrow gap twin wire gas shielded arc welding rifle, narrow gap mariages buries
Arc welding torch, narrow gap bipolar electrode TIG welding gun ".(see a kind of cable formula welding wire narrow clearance welding gun of patent 201811057434.X,
201811342381.6 a kind of narrow clearance welding gun, a kind of 201811337955.0 mariages narrow clearance welding guns).These welding gun performances
Very well, but also there is following two points shortcoming.
1, from the various documents in relation to narrow gap welding it is found that the difficult point of narrow gap welding or being most also easy to produce the position of welding defect
It is that sidewall fusion is insufficient.General welding gun only has a root wire, to fuse both sidewalls, commonly uses the method for wire oscillation, changes
The fusion of kind side wall, but mechanism is complicated, and failure rate is relatively high.The fusion of the side wall of narrow gap welding is still one general both at home and abroad
The problem of all over concern.
2, in the production of factory, according to the difference of materials to be welded kind or the difference or welding quality of product structure
The difference required with speed of welding, often to " narrow gap twin wire gas shielded arc welding, narrow gap double wire hidden arc welding, narrow gap is double
Two silks or two interelectrode distances claim in electrode TIG weldering ".If two silks or two interelectrode distances are close,
Form congruent melting pond (single arc) Double Wire Welding;If two silks or two interelectrode distances are far, off-eutectic pond (double arcs) mariages is formed
Weldering.Congruent melting pond Double Wire Welding and off-eutectic pond Double Wire Welding, respectively there is feature, and application is different.According to the difference of materials to be welded kind,
Or the difference that the difference or welding quality and speed of welding of product structure require, welding engineer can consider comprehensively, determine
Two or two interelectrode distances.
3, in the production of factory, according to the difference of materials to be welded kind or the difference or welding quality of product structure
The difference required with speed of welding, often three of the above welding method plays use, therefore just needs to prepare three kinds of welding guns.Pen
Though person has found that above-mentioned three kinds of welding guns have difference, common ground is also very much.This patent discloses it is a kind of need to only make local replacement or
Change, a welding gun can carry out " narrow gap twin wire gas shielded arc welding, narrow gap double wire hidden arc welding, narrow gap bipolar electrode TIG
Weldering ".The type for reducing another spare part, reduces costs.
