Abstract
The invention discloses a method for welding a box-type steel beam through submerged-arc welding. The method is characterized by comprising the processing steps that firstly, two pieces of angle iron are connected into the box-type steel beam in a butt joint mode through a point welding method; secondly, a section of small angle iron is cut to be manufactured into a movable support for bearing welding flux; thirdly, one connector of the box-type steel beam is made to face upwards and is fixed; fourthly, the movable support is buckled on the connector of the box-type steel beam and is welded through a submerged arc welding machine; fifthly, the box-type steel beam is overturned to enable another connector of the box-type steel beam to face upwards and to be fixed, and welding is carried out through the submerged arc welding machine. Compared with the prior art, the method has the advantages that a welding line is formed at a time, a weldment is heated evenly, and the bending deformation is small; the appearance of the welding line is good and cannot be matched by manual welding; the welding efficiency is high, and the labor intensity of welders is relieved.
Description
Technical field
