Embodiment Construction

[0010] During construction, the angle steel frame is pre-embedded in the concrete base; then each steel plate is welded to the angle steel frame; finally, every two adjacent steel plates are butt-welded. When welding, the welding gap is 5-6mm.

[0011] This welding method solves the problems of poor penetration, low weld strength, and easy cracking under long-term dynamic load operation in the past, making the steel plate ground zero repair and ensuring the normal production of the enterprise. Experience has been accumulated for the promotion and application of steel plate floors in the future, and it has high promotion and application value.

Abstract

The invention provides a method for welding steel plates, comprising the following steps: firstly, pre-embedding an angle iron frame in a concrete base; then, welding each steel plate with the angle iron frame; and finally, connecting two adjacent steel plates in a butt welding manner. The steel plates welded by adopting the method have firm welding and reliable quality, the phenomenon of weld failure without repairing is sovled and the steel plate surfaces are protected from hollowness, thereby ensuring that production of enterprises can operate normally.

Description

Technical field: [0001] The invention relates to a welding method, in particular to a steel plate welding method. belongs to the field of construction. Background technique: [0002] At present, butt welding is generally used for 5mm steel plates, and the welding gap is 2-3mm. The welding penetration of this method is poor. Hollow, welds are prone to cracking under long-term dynamic load operation, and frequent repairs affect normal use. Invention content: [0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a steel plate welding method, which is used to solve the problem that the original technology causes hollowing on the steel plate floor, and the weld seam is easy to crack under long-term dynamic load operation, and repairs are frequent, which affects normal operation. problem of use. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted b...
