Abstract
The invention discloses an automatic submerged arc welding method for self-propelled drag suction dredger ship building. Impurities like garbage, accumulated water, rust, oxide, sump oil and musky coal are thoroughly cleaned; under quite wet conditions with dew, frost and the like, a welding surface is dried by a cutting torque or an air pipe and polished by air brush prior to welding; run-on plates not smaller than 80mmx80mm in area are applied to two ends of a jointed plate seam, and thickness of the run-on plates shall be identical to a base material, so that welding quality at the head end and the tail end of the welding seam can meet standard requirements. The automatic submerged arc welding method is simple, convenient, easy to operate and good in working efficiency.
Description
Technical field
The present invention relates to a kind of shipbuilding method.
Background technology
Existing trailing suction hopper dredger machine shipbuilding automatic submerged-arc welding method complexity, working effect is undesirable.
Summary of the invention
The object of the present invention is to provide a kind of easy, effective trailing suction hopper dredger machine shipbuilding automatic submerged-arc welding method.
Technical solution of the present invention is:
A kind of trailing suction hopper dredger machine shipbuilding automatic submerged-arc welding method, is characterized in that: comprise the following steps: thoroughly clean by impurity such as the rubbish of the face of weld, ponding, corrosion, oxide, sump oil, plasters; Very moist in the situation that, as dew, frost etc., application cutting torch or airduct will be dried by the face of weld, then can weld with wind brush glazing; The two ends application of jigsaw seam is not less than the run-on tab of 80mm × 80mm, and thickness should be in mother metal same specification, guarantees that the welding quality of weld seam end at the whole story reaches standard-required.
The inventive method is easy, easy to operate, good working effect.
Below in conjunction with embodiment, the invention will be further described.
