Background

Square tubes are generally made of square-section metal tubes, such as steel tubes or aluminum tubes, and square tube welding is a welding method for connecting square tubes, and mainly comprises the following common methods:

spot welding: the spot welding is to connect two adjacent square tubes by spot welding at the contact points, and the welding method is suitable for application occasions with simple connection and low requirements.

Welding fillet weld: the welding fillet weld is formed by welding the corner parts of the two square pipes. This welding method is often used for connecting corner portions of square pipes, and requires high strength and sealing properties of the weld.

Welding butt joint: the welding butt joint is to butt joint one side or two sides of two square pipes to form butt joint welding, and the method is suitable for connecting the side surfaces of the square pipes and has high requirements on the strength and the sealing performance of the welding seam.

Welding the lap joint: the welding lap joint is formed by lap welding one side of one square pipe with the side surface of the other square pipe, and the method is suitable for connecting the side surfaces of the two square pipes, and requires high strength and sealing performance of the welding joint.
