7 Tips for Welding Abrasion-Resistant Plate Modern

When welding AR plates onto new, clean heavy equipment structures in an indoor setting, a solid wire, such as an AWS ER70S-3 or ER70S-6, works wellespecially if the base material is A36. Solid wire does not require slag removal and offers a nice bead appearance.

Fig. 6. Major types of structures associated with lamellar tearing. In butt joints, as the stresses on welding do not act through the thickness of the plate, there is little risk of lamellar tearing. As angular distortion can increase the strain in the weld root and or toe, tearing may also occur Chapter 40 Bridge Rehabilitation - Wisconsin fracture critical structure, just four years after it was constructed. In 1980, on the same structure, major cracking was discovered in the tie girder flange of the tied arch span.

This is one example of the type of failures that transportation departments discovered on welded structures in the 1970's and '80's. FABRICATION AND ERECTION OF STRUCTURAL Nowadays welding is the most common method of shop fabrication of steel structures. In addition to being simple tofabricate, welded connection considerably reduce the size of the joint and the additional fixtures and plates. However, there is still a demand for structural members to be bolted arising from a requirement to avoid welding

Preparing structural steel surfaces for painting, coating

Mill scale, dirt, laser scale, rust, heat-treat scale, grease, and dust interfere with paint and coatings adhesion to structural steel and must be removed before steel members can be coated. What are structural steel fabricators doing about surface preparation, and what options are available? Surface preparation can run from simple chemical cleaning to abrasion methods such as grinding and STRUCTURAL STEEL TERMS/ LAYOUT AND Figure 3-2.Structural shapes. the S-shape is in the design of the inner surfaces of the flange.

STRUCTURE magazine A New Shape for Short Span Steel

The future of short span steel bridge design began in 2009 with a challenge from the Federal Highway Administration (FHWA). FHWA challenged the North American steel industry to develop a cost-effective short span steel bridge with modular components which could be placed into the mainstream and meet the needs of todays bridge owners, including Accelerated Bridge Construction (ABC).

Spiral Welded Pipe - Nucor Skyline

The difference is the coil is wound at an angle, so the weld runs around the outside of the pipe in the shape of a helix. This allows for a lot more variation in diameter and thickness than ERW pipe.

Structural Steel Construction TolerancesFor the most part, the tolerances for welded members are the same as those for rolled members produced under ASTM A-6, even though rolling mill practice has only limited direct bearing on welded built-up members. One particular tolerance require­ ment to insure structural integrity involves the tilt or out-of-square limits for flanges.
