HSS are available in round, square, or rectangular shapes. Round shapes are specied using decimal numbers and three decimal points. For example, HSS 5.563 0.258 indicates a round HSS with

Welding 6061 or 6063 Aluminum Square Tube. 1. When welding thin material, it may be best to AC TIG weld using an argon or helium mix shielding gas. Although this may be not as quick as MIG welding, it's the cleanest and easiest to control. 2. When welding thick aluminum, you should either MIG weld with a spool gun or DC TIG weld with a helium mix. Square And Round Hollow Sections Hss Argon Arc Welding - Image ResultsTables of allowable axial compressive loads, in kips, are presented for square, rectangular and round hollow structural sections ( HSS) manufac-tured by the electric resistance welding (ERW) method and for square and rectangular HSS manufactured by the submerged arc weld ing (SAW) method. ASTM A1065 HSS Steel Tubing - HW MetalsWhile many mills provide ASTM A500 HSS (hollow structural section) steel tubing, they often only provide 20 or 40 lengths and a limited range of sizes/dimensions. This leaves customers with tubing that is either too long (resulting in wasted scrap) or too short (requiring multiple sections to be welded together), and that does not fit the square and round hollow sections hss Argon arc welding

A500 tubing comes in many different names for squares and rectangles, it is referred to as structural tubing, or HSS (or Hollow Structural Sections). Rounds are typically called out as Structural Pipe or pipe size tubes. A500 products are used in applications where loadbearing applications are required. Bending square and rectangular tubing - The FabricatorBending round, square, or rectangular material involves stretching the outside diameter (OD) of the bend and compressing its ID. Consequently, a heavier wall thickness allows for a tighter bend radius and more material stretchability with less distortion. Method of Bending. Cutting opportunities in hollow structural sectionsEnter hollow structural sections, or HSS (see Figure 1). These round, rectangular, or square tubes have shapes that provide inherently higher strength and can span greater lengths between braces. These round, rectangular, or square tubes have shapes that provide inherently higher strength and can span greater lengths between braces.

AISC 360 (AISC, 2010) has adopted Method (ii) in Section K (Table K4.1) for welded connections to rectangular HSS by specifying various weld effective lengths, l e, for different connection types and loading situations. Details of the two methods can be found in an earlier technical paper Welding of Hollow Structural Sections. As a sequel, this paper discusses the special considerations for the application of Chapters J and K in AISC 360 to the design of fillet welds to rectangular HSS. Fatigue testing of butt-welded high strength square hollow square and round hollow sections hss Argon arc weldingIn this study, high strength square hollow section (SHS) tubes were butt welded using Gas Tungsten Arc Welding (GTAW) method. The residual stresses were measured and compared with the results from previous studies. Vickers hardness and metallurgical images on the welded section were used to reveal the HAZ and its microstructural changes. HOLLOW STRUCTURAL SECTIONS - Bull Moose Tubeinto a round (9), square (10) or rectangular (11) section. Form-Square Weld-Square (ERW) Process In the weld mill, driven forming dies progressively shape the at strip (1) by forming the top two corners (2) of the square or rectangular tube in the initial forming station. Subsequent stations form the bottom two corners (3) of the shape.

The term "HSS" stands for Hollow Structural Sections. HSS is a cold-formed welded steel tube used for welded or bolted construction of buildings, bridges and other structures and a wide variety of manufac-tured products. It is produced in square, rectangular and round shapes to meet design requirements. In recent years, HSS has experienced HSS - Pirate 4x4This publication presents SI dimensions and section properties for U.S.customary sizes of rectangular, square and round Hollow Structural Sections (HSS) manufactured by the electric-resistance welding (ERW) process and the submerged arc welding (SAW) process.

Heat Treating HSS. By Jeffrey A. Packer. Bahen/Tanenbaum Professor of Civil Engineering, University of Toronto, Ontario, Canada. HSS in North America are produced as cold-formed members by one of the following methods: (i) Cold-forming into a round initially, closing the section using electric resistance welding (ERW), and then potentially cold-shaping into a square or rectangular section. Hss ProcedureThe two half-sections are fitted together toe-to-toe (4) and welded by the submerged arc process to complete the square or rectangular section (5). In this method, a smooth steel sheet (1) is continuously shaped along the longitudinal axis to Turn the tube with a round cross section. This is done by moving the sheet through a set of rollers (6-2).
