DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, an embodiment 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 embodiment 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, a 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 described. Fig. 1 is a diagram showing an example of the flow of work performed at the factory of a welding contractor who has received a welding request.

[0026] When a welding contractor receives a request from a client to weld a product, the welding contractor obtains documents such as the client's specifications and drawings related to the product from the client. At the welding contractor's side, the 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 checks the documents obtained from the client, confirms the conformity standards corresponding to the welding of the product, the equipment and materials required for welding the product, considers welding inspection, considers post-welding heat treatment, and designs welded joints. When checking the equipment and materials, the welding management engineer checks the welding qualifications, welding procedure, welding equipment, welding materials, welding gas, and consumables used in welding required for welding the product. The welding management engineer checks whether there are qualified people and welding procedure procedures that are suitable for welding the product, and if there are a lack of qualified people and welding procedure procedures, creates a plan to obtain the corresponding welding qualifications and welding procedure. In addition, if there is a shortage of welding materials, welding equipment, welding gas, consumables, etc. required for welding the product, the welding management engineer issues instructions for procurement of the missing items. After checking the equipment and materials, the welding management engineer creates a welding procedure manual based on the materials obtained from the client and instructs the foreman to perform 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 welders who have the necessary welding qualifications to perform the welding work specified in the welding procedure manual. The foreman also prepares the welding equipment to perform the welding work specified in the welding procedure manual, and issues instructions to dispense welding materials, welding gas, and consumables. These instructions are sent to a management center (not shown) that manages the welding equipment, welding materials, welding gas, and consumables, and the management center dispenses the welding equipment, welding materials, welding gas, and consumables in response to the instructions.

[0028] The welders assigned by the foreman use the welding management system to perform welding work (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 necessary welding qualifications to perform the welding work instructed in the welding procedure manual. If they have the necessary qualifications 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 report of work completion and delivery, etc. (step S4).
