ASTM A36 steel plate is the most purchased hot rolled steel plate in the world and the least expensive of the commercial carbon steels. The heat ability reates very good welding properties, and the 36 ksi yield strength makes ASTM A36 steel plate acceptable for most applications. A36 is considered a mild steel due to its relatively moderate hardness.

Gas metal arc welding (GMAW): This process is also referred to as metal inert-gas (MIG) welding uses an uncoated continuous wire. The weld area is shielded from contamination by the gas that is fed through the welding torch.
Accuracy of steel fabrication. Modern steel fabrication involves the manufacture of large and often complex welded assemblies of rolled steel products. High temperature processes are used to make the steel products, to form the components and to join them together, so dimensional variation is inherent and unavoidable.
Fatigue in Welded-Steel Structures. Although fatigue may be of concern for stationary equipment such as power generators or machine tools, it is particularly important when designing and fabricating steel frames for mobile equipment such as agricultural, construction, mining, and material-handling machines.
Remove all coating, rust, dirt and mill scale within one inch of the area to be welded prior to fit-up. Remove all slag, spatter and weld discontinuities between passes. Clean the completed weld of all debris, slag and spatter. Care shall be taken to not exceed 250 in the proximity of the Elastomeric Bearing material.
RE: tolerances for welded steel fabrications. 3 Apr 12 14:31. Tolerances are a design function. The purpose of a tolerance is to define the amount of acceptable deviation from the "perfect" dimension that will still allow a part, component or assembly to function as intended.
Connections to existing steel shall be field welded unless otherwise specified. 5.7 Fabrication Tolerances Fabrication tolerances shall conform to AISC "Code of Standard Practice for Steel Buildings and Bridges." 5.8 Erection Marks 5.8.1 Building Structure Identification When projects involve more than one building structure,

Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section.Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries.
For welding of cold formed steel, I always recommend to use minimum 18 gage. However, when the cold formed steel framing is bearing wall, I recommend 16 gage. When the cold formed steel is thinner than 18 gage, and field weld, the weld is almost impossible.

In most cases, tolerances are not a major issue in the building design process, but can be in special situations. One special case is the interface of the supporting structure with architectural features such as curtain walls. Building facades are frequently very susceptible to tolerance issues.
Shop Inspection Handbook for Structural Steel Buildings 2010 A reference guide for steel fabricators, inspectors and others involved in the structural steel building industry The Shop Inspection Handbook for Structural Steel Buildings is a useful tool for everyone involved with the inspection of steel fabrication for buildings.

Process duct work conveys large volumes of hot, dusty air from processing equipment to mills, baghouses to other process equipment. Process duct work may be round or rectangular. Although round duct work costs more to fabricate than rectangular duct work, it requires fewer stiffeners and is favored in many applications over rectangular ductwork.
The Guide to Standards and Tolerances (the Guide) has been developed for use by builders and building owners as a convenient reference for acceptable standards of workmanship in domestic building construction. It is intended to address areas that are not prescribed under legislation or under a domestic building contract.
