Abstract

The invention discloses a horizontal welding method which comprises the following steps: positioning a to-be-welded first workpiece and a to-be-welded second workpiece, so as to ensure that the to-be-welded surfaces of the first workpiece and the second workpiece are placed at horizontal welding positions; and providing a front-end heat source and a rear-end heat source, so as to ensure that weldsare formed at the to-be-welded parts of the to-be-welded surfaces of the first workpiece and the second workpiece, wherein the energy density of the front-end heat source is higher than that of the rear-end heat source, and the following position relationship between the front-end heat source and the rear-end heat source is met: a first included angle between a first straight line and a fourth straight line, a third included angle between the a second straight line and an eighth straight line, a fourth included angle between a fifth straight line and the eighth straight line, and a sixth included angle between a sixth straight line and a ninth straight line are all greater than 0 degree but less than or equal to 15 degrees; a second included angle between the fourth straight line and a seventh straight line is greater than or equal to negative 30 degrees but less than or equal to 30 degrees; and a fifth included angle between a third straight line and the ninth straight line is greater than negative 15 degrees but less than 0 degree. The horizontal welding method has the advantages of being high in welding efficiency, high in welding quality, low in welding difficulty, and the like.

Description

technical field [0001] The present invention relates to the field of welding, in particular to a transverse welding method. Background technique [0002] The existing flat welding method cannot realize single-sided welding and double-sided forming of the weld seam without setting a liner. In order to realize single-sided welding and double-sided forming of the weld, the pad can only be set on the back of the weld. However, disposing the liner has the disadvantages of high cost and low efficiency. [0003] When welding box-shaped parts, in order to ensure that the box-shaped parts such as the boom of a crane can have sufficient bearing capacity, the process requires that the front and back of the box-shaped parts be well formed, and the root of the weld seam is completely penetrated. At present, when conventional gas shielded welding is used to weld box-shaped parts without a liner, the metal in the molten pool will flow under the action of gravity, and it is impossible to ...
