[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiments described below. In addition, in the description of the drawings, the same or corresponding elements are appropriately designated by the same reference numerals.

[0025] [Embodiment] First, the flow from when a welding contractor using the welding management system according to the present invention receives a welding request to when the welding work is performed will be explained. Figure 1 is a diagram showing an example of the flow of work performed at the welding contractor's factory that has received a welding request.

[0026] When a welding contractor receives a request from a client to weld a product, the contractor obtains the client's specifications, product drawings, and other materials from the client. At the welding contractor's side, a welding management engineer first creates a welding plan using a welding management system in response to the client's request (step S1). When creating the welding plan, the welding management engineer reviews the materials obtained from the client, confirms the compliance standards for the product's welding, the materials and equipment required for welding the product, considers welding inspection, considers post-weld heat treatment, and designs the welded joints. When confirming the materials and equipment, the welding management engineer confirms the welding qualifications, welding procedures, welding equipment, welding materials, welding gases, and consumables required for welding the product. The welding management engineer also confirms whether the contractor has qualified personnel and welding procedures appropriate for welding the product. If qualified personnel and welding procedures are not available, the welding management engineer creates a plan to obtain the corresponding welding qualifications and welding procedures. In addition, if there is a shortage of welding materials, welding equipment, welding gas, consumables, etc. required for welding the product, the welding manager will issue instructions to procure the missing items. After checking the materials and equipment, the welding manager will create welding procedure instructions based on the materials obtained from the client and instruct the foreman to carry out the welding work.

[0027] The foreman, who receives instructions from the welding management engineer, uses the welding management system to prepare for welding based on the welding procedure manual (step S2). Specifically, the foreman assigns, for example, welders with the necessary welding qualifications to perform the welding work specified in the welding procedure manual. The foreman also prepares the welding equipment required to perform the welding work specified in the welding procedure manual, and issues instructions for dispensing welding materials, welding gases, and consumables. These dispensing instructions are sent to a management center (not shown) that manages the welding equipment, welding materials, welding gases, and consumables, and the management center dispenses the welding equipment, welding materials, welding gases, and consumables in accordance with the dispensing instructions.

[0028] The welders assigned by the foreman perform welding work using the welding management system (step S3). Here, the welders use the welding management system to check the welding procedure manual. The welders also use the welding management system to check whether they have the welding qualifications necessary to perform the welding work instructed in the welding procedure manual. If the welders have the qualifications necessary for the welding work, they perform the welding work in accordance with the welding procedure manual using the issued welding equipment, welding materials, welding gas, and consumables. When the welders finish the welding work, they check the quality of the welded product and manage the work completion report, delivery, etc. (step S4).
