With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
tempered alloy steel. T-1 steels can be welded satisfactorily by all major welding processes when proper procedures are used. The most widely used welding processes are the arc welding processes shielded metal arc welding, submerged arc welding, gas metal arc welding, flux cored arc welding and gas tungsten arc welding.
Welding costs have been calculated by many methods taking into account the design, shop-floor procedures and repeatability of a product, length of weld, overheads etc. Usually the cost of weld metal is about three times the cost of steel. Very often, the economics of welded fabrication is judged by the cost of electrodes, arc times etc.

Flat metal mesh sheet offers high rigidity in a variety of sizes and weights. The angles of the diamond strands allow maximum air circulation and distribute stress on the metal to supporting frames. The galvanized steel and black steel expanded diamond mesh is the most versatile expanded sheet materials.
There are two basic methods of producing hollow sections - the seamless process in which a hole is pierced through a hot solid bar to form the bore and then the bar is rolled to form the round tube, and the welded process in which a steel plate or strip is formed into a cylindrical shape and the edges welded together.
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.
The intelligent reinforcement pipe for constructional engineering is characterized in that three reinforcementplates are arranged in the reinforcement pipe, one ends of the three reinforcement plates are connected together through welding, an included angle between every two adjacent reinforcement plates is60 degrees, and the tail ends of the three reinforcement plates are connected with the inner wall of the reinforcement pipe through welding.

When MIG welding mild steel, you can use either the push or pull technique, but note that pushing usually offers a better view and enables you to better direct wire into the joint. Travel angle Normal welding conditions in all positions call for a travel angle of 5 to 15 degrees.
Steel with 2.1% Carbon by weight begins melting at 1,130 C (2,070 F), and is completely molten upon reaching 1,315 C (2,399 F). 'Steel' with more than 2.1% Carbon is no longer Steel, but is known as Cast iron. Fire resistance
include double angles with a square rod bent around the pan and welded to both the pan and the stringer. Stringer to dog leg: A common stringer to dog leg connection is shown in Figure 3.This is a welded connection with both ends mitered. Stringer to ground: A common stringer to concrete floor connec-tion is shown in Figure 3.
According to the test results, the average angle of a stainless steel transverse fillet weld is 29; the average angle of a stainless steel longitudinal fillet weld is 46. The ultimate strength for transverse fillet weld connection is 1.5 times than that of longitudinal fillet weld.
Constructional reinforcement mesh panels made of crimped ribbed steel round wire rods or bars. The welding for steel bar welded mesh is done with spot welders or arc welders. The ribbed steel bars running parallel to the width of the roll are placed on top of the steel bar running parallel to the length.

It is easy to weld, cut, form and machine. Metals Depot stocks hundreds of sizes of steel angle that you can buy online in ready to ship precut or mill lengths or you can order just what you need custom Cut to Size in small or large quantity at wholesale prices.
The Journal of Constructional Steel Research provides an international forum for the presentation and discussion of the latest developments in structural steel research and their applications.
Welded constructional steel joints in particular are highly sensitive to issues of fatigue, weld corrosion and/or weld quality. A key concern is on placing welds in regions of nominal stress. Welded joints are produced to a specification, which is used to minimize the heat-affected zone and any residual stress within the weld.
The HD-24 Angle Weld Bracket is designed to provide adjustability for one-sided forming applications. The bracket is available in 1/2, 3/4 and 1 thread diameters and allows for 110 of maximum swing. The bracket can be welded to any steel construction member using proper welding techniques.

welded moment connections of steel frames [1,2]. Since then, many alternative types of connections have been suggested by researchers, such as bolted top and seat angle connections. These types of connections are categorized as semi-rigid connections  which have not the brittle fracture behavior of corresponding welded connections.
