A hybrid welding method capable of improving arc stability and improving the welding speed and the welding efficiency is provided. A hybrid welding method includes generating a TIG arc on a leading side in a welding direction and generating a MIG arc on a trailing side in the welding direction to weld a base metal, in which a TIG current is set to be higher than a MIG current so as to continuously generate arcs in a TIG electrode and a MIG electrode, and an absolute value of a distance from an intersection between a central axis of the TIG electrode and a surface of the base metal to an intersection between a central axis of the MIG electrode and the surface of the base metal is 20 mm or less.

The present invention provides a method for efficiently producing monosaccharides, oligosaccharides, and furfurals from biomass. A biomass is hydrolyzed under conditions under which monosaccharides, oligosaccharides, and furfurals are produced while continuously supplying an aqueous suspension of the biomass from a supply port of a continuous primary hydrolysis device and moving the suspension through the device. A hydrolysis solution is continuously discharged from a discharge port of the continuous hydrolysis device, and a hydrolysis solution containing monosaccharides, oligosaccharides, and furfurals are extracted from an intermediate extraction port provided at any position between the supply port and the discharge port of the continuous primary hydrolysis device. The extracted hydrolysis solution is then subjected to secondary hydrolysis.
