Embodiment Construction

[0018] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0019] The present invention is described in detail below through specific examples.

[0020] A welding method for H-shaped steel members, comprising the steps of:

[0021] (1) Parts blanking: For the wing plate and web of the H-shaped steel, use a straight cutting machine to vertically blank both sides at the same time, and use a CNC cutting machine for irregular parts;

[0022] (2) Assembling: Check the appearance and cutting quality of the parts. There are no gaps or burrs on the cutting surface. When the depth of the gap is less than 5mm, perform grinding and smooth transition. If it exceeds 5mm, repair welding. The burrs should be polished clean. Carry out inspection and confirmation; use artificial tire frame to assemble H-shaped steel;

[0023] (3) Welding: first use gas shielded welding to weld the connec...

Abstract

The invention discloses a welding method for H-shaped steel parts. The welding method comprises the following steps of (1) carrying out blanking on the parts; (2) carrying out assembling; (3) carryingout welding; (4) shoveling slags; (5) carrying out conveying; (6) carrying out correction; (7) carrying out cutting-off operation; and (8) carrying out polishing. The welding method for the H-shapedsteel parts has the advantages of being simple, and the machined H-shaped steel is smooth in surface, accurate in size and good in consistency.

Description

technical field [0001] The invention belongs to the field of welding, in particular to a welding method for H-shaped steel components. Background technique [0002] H-shaped steel is an economical cross-section high-efficiency section with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-beam are arranged at right angles, the cross-section shape of the H-beam is economical and reasonable, and the mechanical properties are good. When rolling, the extension of each point on the cross-section is relatively uniform and the internal stress is small. Compared with ordinary I-beams, it has a large section modulus. , light weight, and metal-saving advantages can reduce the building structure by 30-40%; and because the inside and outside of the legs are parallel, and the legs are at right angles, they can be assembled and combined into ...
