<p>A welding system (400) and method is provided for welding heavy plate (W), where the method and system (400) include using a laser (201) which directs a beam (203) to a first weld puddle (209A) to weld at least a portion of a work piece (W). A welding torch (205) having a first welding electrode (207) may be directed to the first weld puddle (209A) while the laser beam (203) is being directed to the same weld puddle (209A). Thus, the welding torch (205) may deposit the first welding electrode (207) to create a first weld bead (209). A flux nozzle (211) is employed to deposit a welding flux (F) onto the weld bead (209), and at least one submerged arc welding torch (213; 215) is used to direct a sub" merged arc filler metal (214; 216) to the weld bead (209) to create a second weld bead (217) through a submerged arc welding process, where the submerged arc welding process melts a portion of the first weld bead (209) to consume the melted portion into the second weld bead (217).</p> |
