On-site welding process for steel structure

Abstract

The invention discloses an on-site welding process for a steel structure, and belongs to the technical field of steel structure welding. A welding rod drying box matched with the process for use is arranged and can dry welding rods required during welding. After the welding rods are dried, a heat preservation cylinder is used for carrying out heat preservation and moisture insulation on the dried welding rods, and the situation that after the welding rods are taken, water enters the welding rods, and the welding effect is affected is avoided. Compared with the prior art, the multiple welding rods are arranged in independent supporting rods to be dried, the situation that drying is uneven due to the fact that the welding rods are stacked together is avoided. When the dried welding rods are taken out, the heat preservation cylinder is inserted into the inner side of a discharging groove, the dried welding rods can automatically fall to the inner side of the heat preservation cylinder, and the situation that when the welding rods are taken out, a frame body is opened, and heat in the frame body is lost is avoided. External humid air entering the frame body and the heat preservation cylinder is reduced as much as possible, and the drying effect of the welding rods and the using effect of the heat preservation cylinder are further improved.

Description

technical field [0001] The invention relates to the technical field of steel structure welding, and more specifically relates to an on-site welding process for steel structures. Background technique [0002] Welding manufacturing of steel structure begins with the preparation of welding production, which includes structural review, process plan and process specification design, process evaluation, preparation of process documents and quality assurance documents, ordering raw materials and auxiliary materials, outsourcing and self-made Design and manufacture assembly-welding equipment and equipment; then start the welding structure manufacturing process from material storage, including material re-inspection storage, material preparation and processing, assembly-welding, post-weld heat treatment, quality inspection, and product acceptance; interspersed Rework, finishing and painting; the whole process of final qualified product storage. [0003] When welding steel structures...

AI Technical Summary

Problems solved by technology

[0005]Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a steel structure on-site welding process, which can realize the drying of welding rods used in conjunction with the process It can dry the welding rods needed for welding, and use the insulation cylinder to keep the dried welding rods warm and moisture-proof after the welding rods are dried, so as to avoid the moisture entering into the welding rods after the welding rods are used to affect the welding. As a result, compared with the prior art, multiple welding rods are placed in independent support rods for drying, which avoids the occurrence of uneven drying of the welding rods piled up together, and when the dried welding rods are taken out, the insulation tube Plugged into the inner side of the discharge chute, the dried welding rod can automatically fall off to the inner side of the insulation cylinder, avoiding the loss of heat in the frame caused by opening the frame when taking out the welding rod, and minimizing the entry of humid air from the outside In the frame and the insulation cylinder, the drying effect of the welding rod and the use effect of the insulation bucket are further improved
