How Steel Sections Are Joined

Description

Steel sections are joined with rivets, bolts, or welding. Each method fits different structural needs and working conditions. These fastening techniques help assemble strong steel structures in practical ways.

Riveting uses cylindrical steel fasteners with a specially designed head. The rivets ar...

钢构件可以使用铆钉、螺栓或焊接进行连接。

铆钉是一种钢制紧固件,具有圆柱形的杆部和特殊形状的头部。

将铆钉在锻炉中加热至白热状态,趁热插入连接件的孔中,然后使用气动锤在第一颗铆钉头的对面锻造成第二颗铆钉头。

通常,螺栓被安装在比螺栓直径大1/16英寸的孔中。在拧紧螺母之前,通常会在螺栓一端或两端下方放置硬化钢垫圈。

螺栓通常使用气动或电动冲击扳手进行紧固。

在焊接过程中,待连接的钢件与金属电极之间会产生电势差。

当电极靠近钢构件的接缝处时,会形成一个连续的电弧,熔化钢构件和电极尖端的特定区域,从而形成熔池。

电极沿着焊缝逐渐移动,持续沉积金属焊道,金属冷却后凝固,在钢件之间形成无缝连接。<...
